Introduction
Description
This new Central Processing Unit, the CPU3, has a faster
processor and more memory than the CPlJ2. These en-
hancements enable it to support the additional functions
described in this manual.
The software for this CPU3 will bear “200” Series num-
bers; that for the standard board, CPU?,
“100” Series numbers.
Upgrading to the TCIV Plus System
Replacing a CPU2 with a CPU3 will upgrade a stan-
dard Telecenter@ IV system to an enhanced Telecenter
IV Plus system.
Copying the Existing Programming
The CPU3 will accept the same user programming as
the CfU2. Thus, you can copy the EEPROM settings (Ar-
chitectural Numbers, Attributes, Location Codes) from
the CPU2 to the CPU3’s EEPROM. You will have to add
programming for any new features you intend to use (e.g.,
Media Retrieval). If you want to copy the old user pro-
gramming, do so before removing the CPU2 from the
system (see the “TCPU3 Diagnostic Program,” further on).
Note: The T6 Diagnostic Program works only with the
CPU2, and the TCPU3 Program works with the CPU3. The
two programs are sold together on the current diagnostic
disk. To make it clear which program is used with which
CPU, the Zprogram has been renamed the TCIW2 but is
otherwise unchanged.
Installing the CPU3
The CPU3 is simple to install:
Step 1. Turn off all power to the system.
Step 2. Remove the front panel and the front locking
bar inside. Unlock the flat-cable connector from the CPU2
by spreading apart its plastic “jaws.” Pull off the flat cable
and any other connector, then remove the board.
Step 3. Insert the CPU3 into the CPU slot in the main
chassis, push on the connectors you removed from the
CPU2, and lock the flat-cable connector’s plastic “jaws.”
Replace the locking bar and the dress panel.
Media Retrieval
Overview
IL0342 on the next page shows the major components
of the media retrieval function. The viewer uses a dialing
Telecenter phone to “call” a particular MRlOO module.
Once connected, the user presses the phone keys to
control the associated video player; for example, pressing
a “2” will cause a player to starf running a program. The
player then sends its output to the user’s television re-
ceiver via an MATV cable (Master Antenna distribution
system for Television).
In effect, the phone keypad becomes a very remote
control. Thus, instead of carting players about, an insti-
tution can mount them all in a secure room, such as a
Media Center.
Access to the media lines can be restricted. Each Dialing
Staff Phone (see below) can be given or dcnicd the power
to directly gain control of the video players. All Adminis-
trative phones automatically have direct access to the
players, and all display phones have the added power of
assigning any media lint to any di:lling phone, and of
reassigning control at any time.
Instructions for installing the MRlOO module and the
MR200 chassis are in KI-1638. This section tells how to
program the media lines, establish a media-center line to
supervise them, and control a video player from a Telecen-
ter phone. Refer also to the “Overview” illustration on
page 3and the “Programming Summary” on page 4.
Note: The DSP (Dialing Staff Phone) line is covered in
its own section of this manual, because it entails far more
than Media Retrieval.
MRlOO ROM Versions
Important: The keypad layouts described in this man-
ualaresuppliedbyMRlOOmoduleswitl~Version6orlntcr
ROMs. The earlier ROMs supply different layouts, cspc-
cially for the laser function mode.
Media Line
A media line is a modified LLM line connected to an
MRlOO module (see KI-1638 for the installation of a
special E & M hybrid, supplied with each MRlOO). It
conveys standard DTMF tones (sent from the user’s
phone) to an MRlOO mtxiule. ‘l’hc moclulc, in turn, tr;lns-

TELECENTERWPLUS System:
Programming for Media Retrieval
IL0343 (01

TC4411 CPU3 for TCIV Plus
lates these tones into commands that the associated video
player can understand. There are only two types of pro-
!gramming
for this line: selecting the line type, and enter-
ing optional automatic control signals.
Media-Line Type A:4
Program each
MR1OO’s line as “A:4.” Turn off all the re-
maining “A” Attributes and
“B” Attributes 3-8. Select the
first two
“B” Attributes according to the next subsection.
Automatic Setup Signals
Users prefer having a player “ready to go” when they
first connect with its media line. The major responsibility
for effecting this state of readiness will fall upon a staff
member assigned to the media center. Among other
things, this person will see to it that the players are turned
on, loaded with the desired programs, and properly cued.
The Telecenter system offers an automatic way of supple-
menting this setup. You can program each media line to
automatically receive one set of DTMF tones when a user
first calls and assumes control of a player, and another set
of DTMF tones when the user
relinquishes control of it or
the Media Center uses the #24 function to end a user’s
control. Neither set is sent when the Media Center uses #24
to assign a player to another phone, when a user hangs up
without relinquishing control of the player, or that user
subsequently calls the player back. Selecting the tones
will depend primarily upon the type of player involved.
Laser-Disk Players: A representative example would
be sending the initializing tones for zero (0) and asterisk
(*). This will set the keypad to the function mode and put
the image on the screen, so that the user can immediately
begin operating the player or specify “frame” or “chapter”
before entering its number. The need for this resetting
arises from the standard way of releasing a laser-disk
player, which is to enter the numeric mode and hang up.
VCRs: A representative ending tone would be sending
a “5” to “stop” the player and a “1” to “rewind” the tape
for the next user. A possible initializing tone would be
sending a “2” to start playing the tape.
Programming the Signals: There are two steps to
establishing these automatic signals: listing them in the
appropriate Location Codes, and setting each media
(A:4)
line’s first two “B” Attributes to select the Location Codes
with the desired tones.
To accommodate different kinds of players, you can list
three
different sets of tones. Each set can consist of two
parts: a group of initializing tones (sent when the user
calls the line and gains control of the player) and a group
of ending tones (sent when the user ends control of the
player, by pressing “0” and hanging up).
The table at the top of the next column, describes the
three sets. The “Sclcctor Attributes” column tells how to
use a media line’s “B” Attributes to select the desired pair
of Location Codes. If you want only initializing or only
ending tones in a
set, simply leave that set’s other Location
Code blank (0).
The
Telecenter system sends the tones in the order that
they are listed in these Location Codes. The following

formula shows how to compute the number to be stored
at a Location Code to get a specific tone sequence:
number = Tone 1 + (Tone 2
x 16) + (Tone 3 x 256)
+(Tone 4 x 4096)
Obtain the numbers of the desired tones from the table
below. Enter the tones in a Location Code in the order
you want them sent. You can set a Location Code to
“0”
for no tones or program it for one tone to four tones.
Programming Codes for Phone Keys
“‘Ignore further entries in this Location
Code”-do not USC.
*“Busy signal”-do not use.
3”Dial tone"--do not use.
‘“Quiet, no tone”-do not use.

TC4411 CPU3 for TCIV Plus
Example: The following initializing tones would set up
a laser player for a caller by setting the keypad to the
function mode and showing a frame and its numbering
on the screen:
“O-*” (this combination assures that the
keypad will be in the function mode) and
“9” (“Show
Frame and Chapter Numbers on the Screen”). To estab-
lish these as initializing tones at Location Code 64274,
64298, or 64302, enter “2490”:
10 [0] + (16 x 11)
[*] + (256 x 9) [9] =
10 + 176 + 2304 = 2490
Media-Center Phone
Any Administrative display phone can be used to super-
vise Media-Retrieval operations. This includes program-
ming the system, reviewing the current users, and
assigning or canceling the use of individual media lines.
Standard Arrangement: Ordinarily, an Administrative
display phone in the Media Center will handle these
functions. In this way, the person receiving media calls
can respond to calls by attending to the video players (e.g.,
loading the desired program and checking on problems).
The Media-Center line must be a standard Administrative
line (A: 1) but requires no special attributes.
Optional Programming: It may prove helpful to pro-
gram a Media-Center phone to receive calls from Display
Driver 2, and use Display Driver 1 for the Administrative
phones receiving non-media call-ins. Adding the A:7 Attri-
bute would immediately connect someone calling the
Media Center to an associated speaker.
Note: A TC4400 Call-Control Console is designed pri-
marily for interconnect functions; it is not recommended
for Media-Retrieval functions.
Location Code 65388: Entering the Physical Number
of the Media Center’s phone here enables anyone com-
municating with an MRlOO to call the Media Center im-
mediately by flashing the hook switch, and to return
directly to the MRlOO by hook-flashing again. This quick-
transfer method can prove helpful when a user encoun-
ters difficulties, such as finding that the wrong tape or disk
has been loaded. To disable this function, store a zero at
this Location.
Caller ID: Starting with Version 204 system software,
any display phone will show the number of another
Telecenter phone that dialed it. The caller’s number will
appear on the right end of the display, in the “last-num-
berdialed” field. To indicate which number it is display-
ing, the system will put a colon (:) before the last number
dialed (as usual) and a “greater-than” (>) sign before a
caller’s number.
Media-Related Operation
Most of the functions described here pertain to the user
who “calls” an MRlOO and
uses the telephone keypad to
control the video player. The #24 supervisory function,
for reviewing and changing users’ connections to MRlOO
lines, can only be used by Administrative display phones,
and is especially intended for a Media-Center phone.
Controlling a Player
This section gives detailed instructions on controlling
a video player from a telephone. IL0344, at the back of
this manual, is an illustrated summary of these functions.
Establishing and Relinquishing Control
Note: If your DSP phone is not programmed to access
a media line directly, call the Media Center to have the
desired line assigned to your phone.
Optional Single-Digit Dialing: Telecenter@
systems
with Version 204 or later software can provide singledigit
access to a media line already assigned to your phone. You
would originally gain control of a media line through
dialing its full number or by having the Media Center
assign it to your phone. Thereafter, until you released the
media line, you could simply dial a single digit (e.g.,
“7”).
and the system would look to see which media line is
assigned to your phone and connect you to it.
Step 1. Tune the television monitor to the channel
assigned to the desired video player.
Step 2. Use the room phone to dial the number of the
desired player.
» The system will send a short beep when it has given
you control of the player, and will continue to beep
at one-second intervals.
(If someone else already has control, the system
will send you a busy signal. If your phone is not
authorized to call an MRlOO line, the system will
send you a single, long “disallow” beep; in this case,
call the Media Center to have the line assigned to
your phone, then repeat Step 2.)
Step 3. After gaining control, use your telephone’s
keypad to operate the player (see the next subsection).
Step
4. To operate the keypad, keep the receiver off-
hook. Once the player is running the program and you do
not need to send any more control signals for a while, you
can hang up.
» The player will continue running, and its media line
will remain assigned to you, which means no one
else can access it (unless the Media Center inter-
venes with the
#24 function or an Administrative
phone with a call-in attribute,
B:7 or B:8, dials the
line). Hanging up frees a Telecenter link for other
functions
and lets you receive or make other calls.
Step 5. To resume sending control signals, call that
media line back from the same phone, as in Step 2. (In a
system with version
204 or later software, you maybe able
to dial a single digit, like
“7,” to reconnect with whichever
media line you still control.)
Step 6. If you need to contact the Media Center while
you are connected to the media line (e.g., because you
need a
different program or there is a malfunction), simply
flash the
hook switch (quickly press and release it).
You will be temporarily disconnected from the
media line and will ring the Media Center line (or
be connected to its associated speaker).
Note: If your system does not use this function, hang
up as in Step 4, then call the Media Center; you will retain
control of the player and be able to dial it back.

TC4411 CPU3 for TCIV Plus
Step 7. To end the connection with the Media Center
telephone and return to the player, flash the hook switch.
Step 8. To relinquish control of a player, dial “0” and
hang up.
Operating a Player
The illustration at the end of this manual (IL0344)
identifies the functions of the keypads. This section will
explain those that are not self-evident and give some
examples of typical operations. Because the control func-
tions are flexible, you can many more things than can be
described here.
In general, the keypad commands parallel the layout
of a typical remote control.
Which Laser-Disk Mode?
With a laser player, a picture indicates the func-
tion mode. The numerical mode always displays a
blue screen; if the “Show Numbers” key has been
selected, it will display numbers. However, the
“Pause, Blank Screen” key (5) in the play mode also
shows a blue screen. Pressing the “2” key should
start the disk playing if the “freeze” function is en-
gaged, but will have no visible effect if you are in the
numerical mode.
VCR (Video Cassette Recorder) Commands
This mode uses the first six keys and “0.” Some keys can
work in combination with others. For example, “Fast
Forward” (3) and “Fast Reverse” by themselves advance or
rewind the tape rapidly without displaying a picture.
Pushing either one while the tape is playing runs the
picture rapidly on the screen in a “search” function.
Note: The VCR model may affect some operational
details; look for an instruction sheet from the Media
Center or experiment with the keypad commands.
Laser-Disk Commands
There are two laser-disk command sets. The numeric
mode, discussed in the next paragraph, is for entering
chapter and frame numbers, which are typically found on
“educational” disks; other disks, like those containing
motion pictures, may not have this numbering. The func-
tion mode, discussed on the next page, requires a key-by-
key description.
Laser Numeric Mode
On “educational” disks, each motion sequence has 30
frames per second of viewing time, and each frame can be
shown as a still picturcor selected asastartingorstopping
point. Some disks have “slides’‘-individual pictures re-
corded as a series of single frames on the disk. These have
to be stepped through, one by one; pressing “Play” would
result in a rapid, confusing succession of images, like a
run-away
slide projector.
TO Select a Chapter:
In the function mode, dial “O-
[Chapter Number]-*.” For example to select Chapter 11,
dial “01 1 *“:
0
= Go to the numeric mode and interpret the key-
pad entries as a chapter number.
11 = Chapter 11.
* = Put the first frame of the chapter on the screen
and return to the function mode.
» The first frame will appear frozen on the screen;
pressing “2” (“Play”) will cause the laser-disk player
to begin running the program from that frame.
To Select a Frame: In the function mode, dial “8”-
[Frame Number]-*.”
For example, to select Frame 41222,
dial “841222*“:
8 = Go to the numeric mode and interpret the
keypad entries as a frame number.
41222= Frame 41222.
* = Put that frame on the screen and return to
the function mode.
»The first frame will appear frozen on the screen;
pressing “2” (“Play”) will cause the laser-disk player
to begin running the program from that frame.
To Select a Stopping Point: The above two proce-
dures select a starting point. To select a point at which
the program will automatically halt, use the above formu-
lae but enter a
"#” instead of a “*” as the final keystroke.
You can select the stopping point either before or after
selecting the starting point.
» The keypad will return to the function mode, and
the last frame that was on the screen will reappear.
Note: Some disks have built-in stop marks between
chapters. These could stop the program before it hits the
stop mark you set in the numeric mode. Pressing “Play”
again will cause the disk to run again until it hits your stop
mark (or another intervening stop mark on the disk).
Selecting Audio Channels
Some stereo disks are bilingual, using the left
audio channel for a narrator in one language (e.g.,
English) and the right audio channel for a speaker.
in a second language (e.g.,
French) . Since the Pio-.
neer player’s default audio mode is stereo,. the result
would be hearing the two narrators simultaneously.
Selecting just Channel 1 (7) or just Channel 2 (*)
is done with a single keystroke in the function mode.
Selecting the combined Channels
1 and 2 is done by
pressing “O-#.” Once you have sclcctcd an audio
function, it will remain in effect ‘until you change it.
#24 Media-Center Control Function
This function allows a display phone to review and, if
necessary, terminate a user’s control of a media line.
Dialing “#24” will display the first video player’s status in
the following manner:
IVCH717=10j]

TC4411 CPU3 for TCIV Plus
“VCR” indicates the player’s line, which may be either
a video-tape or a laser-disk player. The first display shows
that the player on Media Line 7 17 is currently assigned to
phone line 105. The second display indicates that player
7 18 is currently available.
releasing a Media Line, any Administrative phone with a
call-in Attribute (B:7 or B:8) can gain control of that line
by calling it. However, only the
#24 method allows you
to assign control to another user.
To pre-assign a player to a specific station: Enter the
Architectural (dialing) Number of the station. The display
will then list the new station owner. Unless an Adminis-
trative phone intervenes, only that owner can call this
player, and the player will receive the initializing tones
when it is called.
Note: It is possible for an Administrative phone to use
the normal call-transfer function
to”transfer” a Media Line
to another phone. However, this method is not recom-
mended because the original “caller” would retain control
of the media line. Thus, the user who received the transfer
could not call the media line back after hanging up.
To terminate a connection: Press the asterisk ("*“)
key on your dial pad. The display will show that the line
is “Free.” Pressing the
"*"” key when the player is already
“Free” will send the ending tones to it (see “‘Automatic
Control Signals” under “Media-Related Programming,”
above).
Notes: This method works whether or not a user is
connected to a Media Line. If a user has hung up without
Alternate Releasing Methods
MR100 Reset Button: This is meant to release a
player from a user who has finished with it but failed
to relinquish control before hanging up. Unlike the
#24 method, this method does not send ending tones
to the player.
“VCRxxx = 65535”: The #24 review function will
show this value instead of “Free” for a player that was
released without receiving the appropriate ending
tones (“0” for a laser-disk player, “0” or “5” for a VCR).
To eliminate this setting, call the player, then release
it with the appropriate ending tones.
To view the next Player extension: Press the
“#" key.
When you have gone through the entire listof player lines,
the words “END LIST” will appear in the display, and the
system will ignore any subsequent key entries. To end the
review at any point, hang up.
Dialing Staff Phone (DSP) A:24
This line type is similar to an Administrative line but is
typically used in a room with a speaker (and sometimes a
call switch). DSPs receive dial tone and may dial calls
directly just like an Administrative phone. The differences
are that a DSP cannot have a display, receive call-ins from
room stations, activate alarm tones, or do executive
over-
ride. These restrictions free “B” Attributes 5, 6, 7, and 8,
which serve other purposes (see “DSP Attributes”

mediately below).

“Resistor Gnd for Priority” = 16
“Resistor Call to LCD2” = 128
Total 248
To make this Set
l, store “248” at LocationCode65390.
Selecting a Set
On each DSP line, enter the combination of “B:5” and
"B:6” that specifies the Location Code with the desired set
of Indirect
Attributes.
For cxample, to select Location Code 65394 (Set 3),
enter "B:6." Note that omitting “B:5” and “B:6” automat-
ically selects Location Code 65390 (Set 1). Thus, to give
all DSP phones the same set of Indirect Attributes, store
this set at Location Code 65390, and simply leave the “B:5"
and “B:6” bits deleted from the individual DSP lines.
Single-Digit Dialing (64278-64296)
The “DSP [Dialing Staff Phone] Single-Digit Dialing
Codes” table below works exactly like the Administrative
single-digit table at Locations 64016-64034, including
echo-digit and circular-hunt capabilities. This primarily
involves storing a Physical Number at one of the Locations
to direct calls from DSP phones to that line whenever the
corresponding first digit is dialed. Use this table only for
DSP phones. DSP phones, in turn, do not respond to data
stored in the main single-digit table. This allows DSP
phones to be restricted from interconnect or from dialing
each other, or to be given single-digit access to selected
locations.

Single-Digit Reconnect
Starting with Version 204 system software, you can
program the system so that a user can be reconnected
with a media line by dialing the programmed digit (e.g.,
“7”). When this digit is dialed, the system checks to see
which media line is assigned to the user’s phone. Thus,
all dialing phones can use the same digit to reconnect with
their own media line. If the user does not have control of
a media line, the system will give a disallow “beep.”
To set up this function, enter the lowest Physical Num-
ber of the media lines in the appropriate Location Code
(see the “DSP Single-Digit Dialing Codes” table, above).
The system will check each media line in succession for
the caller’s number, similar to what it does in the “hunt”
function (however, it is not necessary to set the hunt bit
on the media lines).
DSP Calling with Dial Pad
Pressing the "*"”
is equivalent to grounding the “T”
terminal and will produce a call-in according to the pro-
gramming of the “D” Attributes. Pressing the “*” twice
within about 1 second is equivalent to a resistor call-in; it

will persist even if the caller hangs up. If the remote-can-
call switch for calling in from another part of the room.
celing feature is enabled, the call-in can be canceled by
Through the “D” Attributes, the phone and the switch can
picking up the phone again and hanging up without
make different types of call-ins, which could go to differ-
dialing anything. The phone can also have an associated
ent LCD drivers.
Monitor, Serial-Port, and Memory Functions
Alternate EEPROM Memory
Like the standard CPU2, the CPU3 has a second block
of EEPROM memory for storing either a back-up copy of
the user programming or an alternate set of programming
that could be used at night, during weekends, etc. What
is new on the
CPU3 is, first, that this block can be accessed
by grounding MI0 terminal “A70.” Grounding "A70”
causes the system to run off this alternate programming.
to change this programming, use the
#99 and #98 func-
tions. Third, the
TCPU3 diagnostic program can program
this block without applying the
“A70” jumper, setting the
program jumper to “enable,” or turning off the Monitor
Lock (see “Preventing Programming Changes,” below).
Note: Starting with Version 204 system software, after
the
#98 or #99 function has started, the displaywill show
a “1” or a “2,” indicating which EEPROM block you are
working with.
TCPU3 Diagnostic Program
The new TCPU3 Diagnostic Program begins by check-
ing whether it is connected to a CPU2 or a CPU3. If it
detects a
CPU2, it lets you select the TCPU2 (formerly
called the
T6) program; if it detects a CPU3, it automati-
cally loads its new diagnostic mode.
This new mode is very different from TCPU2, which
works with the S-bit CPU. Some differences are:
a. The TCPU3 uses a special protocol to set the CPU3
baud rate, which can be as high as 9600.
Note: Adding “128” to Location Code 64268 will
prevent the TCPU3 from changing the baud rate on
a CPU3; this is explained further on, under “Baud-
Rate Selector.” (This setting is irrelevant to the
CPU2, because its baud rate is set by a hardware
jumper.)
b. It uses binary packets instead of ASCII hex files
when making memory-block transfers. This in-
creases speed and reliability.
c.
It can override both the hardware EEPROM lock-
out jumper the software “Monitor Lock,” even
from a remote location.
d. It addresses separate EEPROM blocks by software
and so does not need a ground jumper on “A70,”
as explained in the preceding subsection.
e. The
I/O diagnostic contains more information and
does not
require halting.
f. It can use application programs to review or mod-
ify the
EEPROM set-up data.
Important: To copy programming from a CPU2 to a
CPU3 follow this sequence:
1) Start the “TCPU2.Exe” (new name) or “T6” (old
name) program.
2) Save the CPU2’s programming to the computer’s
disk.
3) Install the CPU3.
4) Restart the TCPU3 Diagnostic Program.
5) Copy the programming from the disk to the CPU3.
Alternatively, if you are unsure which CPU you are
working with (e.g., because you are working via a modem
at a remote location), you can start the TCPU3 program.
If it detects a CPU2, it will prompt you to load the TCPU2
program. If you do this, you must restart the TCPU3
program before workingwith the CPU3. The new diagnos-
tic program checks which CPU it is working with at the
beginning. If you switch to the CPU3 after the program
has started, it will continue operating in the TCPU2 diag-
nostic mode, which will not work properly with a
CPU3.
Preventing Programming Changes
There are two basic methods of preventing unautho-
rized changes to the user programming: the hardware
programming jumper on the CPU board, and the software
“Monitor Lock” function (Location Code 64 100). When
either lock is engaged, the
“#” programming functions
can still read and display existing programming entries.
When used by itself, the hardware lock allows attempted
programming changes made by an Administrative phone
to appear on the display, but the system will not save
these
changes. The software “Monitor Lock” does not even
allow attempted changes to appear on the display.
Diagnostic Override
Note that either of these locks can be bypassed via the
serial port, which would be used by a computer with the
TCPU3 Diagnostic Program. This port ignores the software
Monitor Lock but requires a command to override the
hardware jumper: simply go to the “terminal mode” and
type l0lE=l0 (note that the last character is the letter
“0,“ meaning ”output”).
To restore the functioning of the
hardware jumper after using this command,
either type
lOlC=lO or reset the system.
Programming-Disable Jumper
This prevents all changes to the programming
even if
the software “Monitor Lock” is “open.” This three-pin
header is on the front middle part of the CPU board. Place
the sleeve jumper in the “N” position to enable the pro-
gramming function or in the “D” position to
disable the
programming function. As expained in the preceding
paragraph, this jumper can be
overridden by a computer
connected to the board’s serial port.
Monitor Lock (Location 64100)
When the hardware programming jumper is in the
“enable” position, this software function can prevent

TC4411 CPU3 for TCIV Plus
changes to selected parts or all of the user programming.
Simply consult the table below, add the “bits” for each
function you want disabled, and enter the total in Loca-
tion Code 64100. For example, to disable all functions,
enter
“15” (1+2+4+8).
Bit Function to be Disabled
#96
97, 98, and 99 functions disabled. Display
1 phones cannot change EEPROM data (see the
note below).
2 #31 Night-answer user switching disabled.
4 #73, 74, 75, and 76 diagnostic functions disabled.
Monitor “Go” function, serial-port changes to the
8 EEPROM, and output commands are all disabled
(see the note below).
Note: Even when the "#” and “Monitor” functions are
disabled, you can still review the current settings.
Technical Information
The following information is for technicians diagnosing
the system.
Baud-Bate Selector (Location 64268)
This setting controls the rate at which data can travel
through the serial port, used by a computer for diagnostic
purposes. This Location Code sets the initial baud rate
after the CPU3 has been turned on or reset. Select the
appropriate entry from the following:
0 300 baud
1 1200 baud
2 2400 baud
3 4800 baud
4 9600 baud
5 19,200 baud (not used by the TCPU3)
Note: Entering any other number at this Location Code
will select the default setting of 1200 baud. Adding “128”
to this Location Code will prevent the
CPU3 from adjust-
ing its baud rate in response to the TCPU3 program.
