RC-85 Repeater Controller
Version 4
New Features ... Not in the V3 Manual!
User’s Features
IC-9 Support
The new software supports IC-900 band units as remote base transceivers,
interfaced via the FC-900. Refer to the FC-900 Manual for details.
Reverse Patch Answer Acknowledgement
hen the reverse patch is answered over the air, a “beep-beep” acknowledgement
is sent over the air to confirm connection.
Touch-Tone Access Up Message
hen a user brings Touch-Tone Access up, the controller acknowledges with
“up”.
Control Operator
The following new Control Operator level commands are available. They are
included in the command summary at the end of this section.
Macro Set Selection Commands
A fifth macro set is available. It is selected with the following Control Op
command.
5M5 Macro Set 5 Select Selects Control Op Macro Set #5
Disable Autopatch Phone Number and Autodial Location Readback
68 NR Disable Autopatch Phone Number and Autodial Location
Readback (and dial without click)
This new command is mutually exclusive with the existing commands:
60 NC Dial Needing Click
59 XC Dial ithout Click
Reverse Patch Mode 3
67 R3 Reverse Patch Mode 3 select
Mode 3 is similar to Mode 0 except that it is optimized for talkback paging
applications. Upon answering the phone, the controller expects a four digit
paging code. The paging sequence is activated over the repeater transmitter,
and the caller is placed on the air. The call may be answered from the repeater
and will then proceed as a reverse patch. If not answered within the
programmable Talkout Timer period, the controller will hang up on the caller.
Entering a # from the phone returns the controller to Mode 0 temporarily for the
duration of the call.

Programming the Controller
Timers
*4012(period) ID ID Timer Pending ID Period. Recommend 360
seconds for amateur repeater.
*4013(period) RO Ringout Timer Determines how long reverse patch
rings over the air. Phone stays off
hook for 60 seconds, even if ringout is
shorter or longer.
*4014(period) TK Talkout Timer Reverse Patch Mode 3 Talkout period
limit. If not “answered” from over the
air during this period, the controller
will hang up.
*4015(period) AL Alarm Timer Limits the period that the alarm
message will be generated over the air.
Command Code Prefixes
*5019(prefix) Touch-Tone Pad Test Prefix
Avoiding Command Code Conflicts
Previously, each command code needed to have a prefix programmed. To avoid a
potential conflict, it was recommended to program an “out of the way” prefix.
Now it is possible to disable the command code by programming it empty. For
example, if you will not use the Touch-Tone Pad Test, simply program (with the
controller unlocked) *5019.

Version 5!
For the ‘96 and ‘85
Introduction
The new Version 5 firmware for your RC-96 or RC-85 Repeater Controller adds
the following exciting features:
• Time of day clock and calendar
• Scheduler
• Expanded vocabulary - FEMALE and sound effects
• Support of an HF remote base
• Miscellaneous additions and improvements
These features are easily added to your existing Version 3 or Version 4 controller
by simply plugging them in!
Description
The time of day clock and calendar is set with Touch-Tone programming
commands, and is battery backed up to keep it running even if your controller
loses power. You can choose 12 hour a.m./p.m. or 24 hour military format.
Several time and date “run time variables” are like synthesized speech
vocabulary, but instead of being fixed words, these variables say the time, date,
a.m. or p.m., the day of the week, and morning/afternoon/evening when
programmed into messages. These run time variables can be included in any
messages (IDs, tail messages, bulletin boards, etc.) using the message editor.
The scheduler works in conjunction with the time of day clock and your existing
macro sets. It relieves you of the chore of repetitively manually selecting differ-
ent macro sets at different times of the day and days of the week. It’s like an
automatic control operator. ith programming commands, you select the time
and days (every day, weekends only, etc.) for automatic changeover of macro sets
to automatically control everything from Control Op settings to remote bases
and user function outputs.
e’ve added a new voice to your controller to announce the time - and she’ll
really perk up your repeater. She often goes by the name Juliet, and she joins
Romeo in her new duties. Technically, Juliet is the female synthesized
speech vocabulary, and along with some sound effects we’ve added, she brings
the total vocabulary size of your controller to 535.
Many people have asked for the ability to hook up an HF remote base
transceiver to their repeater so they could work HF from their handhelds. Now
you can! The ‘85 and ‘96 controllers each have one link or remote base port, and
now an HF radio can be connected to that port. (If you’re already using
1
V5.2 12/91

your link port for a fixed frequency, BCD, or FC-900 remote, the HF function is
not available). ith the ‘96 controller you’ll need to add a low cost serial port
board available from ACC. The ‘85 controller will connect to the HF radio as-is.
e selected the Kenwood TS-440S HF transceiver because of its clean interface
and its popularity. You’ll have a basic subset of control functions - frequency,
mode, memory recall, and scan (not loading memories, operating the antenna
tuner, controlling a rotor, etc.). The TS-440S is the only radio that we plan to
support - if you like ICOM or Yaesu, try Kenwood. ( e like all three! - we just
don’t support the other HF radios.) And if you have another in Kenwood’s series,
you may want to try it, but we’ve done all our testing with the TS-440S.
Finally, as our controller firmware continues to evolve, we’ve made a number of
miscellaneous additions and improvements based on feedback from owners
and users. The details are outlined at the end of this note.
WARNING: The field installation of the upgrade involves some risk - if you don’t follow the
instructions precisely, or if there is a mechanical problem such as a bent pin, it may be
necessary to return the controller to ACC for repair. We’ve done everything possible to
make the upgrade easy to install. ACC offers to perform the installation at no charge
(except return shipping). If you would like us to perform the upgrade, return your controller
and the upgrade kit to ACC before attempting installation. If you choose to perform the
installation in the field, please recognize the small but finite risk.
WARNING: Version 5 firmware requires 8Kx8 of E2PROM. All RC-96 controllers are
equipped with the necessary 8Kx8. Very old RC-85 controllers (shipped approximately
before February, 1987, S/N 696) may have only 2Kx8 of E2PROM. If your old ‘85 contains a
2815, 2816, or 2817A at socket U27, then you need to upgrade the E2PROM to a 28C64.
Contact the factory for availability before attempting the installation.
WARNING: If you connect your controller to a Kenwood TS-440S transceiver, we strongly
recommend lightning protection for your repeater and site to avoid damage to the expensive
HF radio.
WARNING: If you connect your controller to a Kenwood TS-440S transceiver and plan to
operate on ten meters, be aware that RF emissions from the RC-85 controller may require
addional shielding and filtering for effective operation. See Chapter 10 of the RC-85 Manual
for suggestions.
WARNING: Do not tamper with the label on either supplied module.
Tampering with the labels will void all warranties.
Installation
The Version 5 upgrade consists of two modules which plug into existing sockets
on your controller. They include the new EPROM program memory which
contains the Version 5 firmware, and a time of day clock and calendar with its
built-in lithium backup battery.

RC-96 Repeater Controller
1. If your RC-96 controller has a Tone Panel option, disable Touch-Tone Access
Mode (COP 53) and select Carrier Access (COP 07). Unlock the controller and
store these selections in Macro Set 1 before installing the new firmware. This
will enable you to reprogram the Tone Panel information as required after
installing the new firmware.
2. Remove power from the controller. Be sure that any backup battery is also
removed from the controller before performing the following steps. Remove the
top cover by removing the six side screws.
3. CAREFULLY, with the supplied IC extractor, remove the integrated circuit at
location U29. Replace it with the U29 chip supplied with the upgrade (oriented
so that the pin 1 notch on the chip matches the notch on the pc board).
4. CAREFULLY remove the integrated circuit at location U34. This chip will no
longer be needed, and the socket at U34 will be left empty.
5. CAREFULLY remove the integrated circuit at location U31 - save it for later
use in this step. Replace it with the clock module supplied with the upgrade.
Now plug in the chip you just removed into the socket on the top of the clock
module.
6. You should now have left over the original U29 and U34 chips from your
controller. Go back over the last steps FOR THE ‘96 CONTROLLER, and be
sure that the chips are plugged into their sockets in the proper orientation and
with no bent pins.
7. Power up the controller - it should sign on with the V5.x message. Proceed to
program the new functions of the controller as described the next sections.
RC-85 Repeater Controller
CAUTION: You must either have an 8Kx8 E2PROM at location U27 or have
obtained a 8Kx8 E2PROM from ACC before performing the installation. If the
chip at U27 is a 9864 or 28C64A or other part number ending with 64, then you
may proceed. If the chip is a 2815, 2816, or 2817A (not ending in 64) then you
must purchase an E2PROM upgrade from ACC before attempting the
installation. Call the factory to order the part.
1. Remove power from the controller. Be sure that any backup battery is also
removed from the controller before performing the following steps. Remove the
top cover of the ‘85 enclosure or otherwise gain access to the top of the printed
circuit board.
2. CAREFULLY, with the supplied IC extractor, remove the integrated circuit at
location U28. Replace it with the U28 chip supplied with the upgrade.
3. CAREFULLY remove the IC at location U27 - save it for possible later use in
the step. Replace it with the clock module supplied with the upgrade.
Now, if the chip that you just removed is a 9864 or 2864 or something else 64,
then plug it back into the socket on the top of the clock module. If the chip that
you removed is a 2815, 2816, or 2817A, then plug in your new 28C64 obtained
separately into the socket of the clock module.

4. You should now have left over the original U28 chip from your controller, and
possibly the 2815/16/17 chip. Go back over the last steps FOR THE ‘85
CONTROLLER, and be sure that the chips are plugged into their sockets in the
proper orientation and with no bent pins.
5. Power up the controller - it should sign on with the V5.x message. Proceed to
program the new functions of the controller as described in the next sections.
Initial Selections, Programming, and DIP switches
After powering up the controller with Version 5 firmware, be sure to do the
following programming and selection steps to avoid unexpected difficulties. See
the appendices for command summaries.

programmed as encode and desired on) - 81
Programming (Programming commands shown)
Program your Control Op setup in macro sets so that what you’ve selected above
isn’t undone when you select a new macro set - *5911-*5915
Program Link COS to be high true (previous fixed condition) - *5411
If you have an FC-900 Interface connected to your controller, indicate which
band units are present and which are absent - *530B P
If you have not connected a TS-440S HF transceiver to your controller, program
an empty HF Command Prefix - *5020.
Program the five Permitted Area Codes as empty messages except for the ones
you intend to use (i.e. 1-800, 1-408, etc.) - *1126-*1130.
hen programming setpoints for the first time, zero out all unused setpoints by
loading all zeros - *420S 0 0 0 00 00 1.

Operation
This section describes the operation of the various new features in Version 5.
The new command codes (programming, control operator, and user) are also
summarized later.
Clock / Calendar
The clock and calendar serves several purposes - the time can be played on re-
quest by entering a Demo user command; the time,date, and day of week can be
included in any programmable message using the message editor; the time and
day of week drive the scheduler which automatically selects macro sets.
Decide if you want your clock to operate in 12 hour format (a.m. and p.m.) or 24
hour format (military time). Set the time using one of the following two
programming commands (entered with the controller unlocked). The
command you chose will determine the format. It will also be necessary to load
the scheduler setpoints below using the same format.
Set Time (12 hr mode) *4100 AP H10 H1 M10 M1
Set Time (24 hr mode) *4100 H10 H1 M10 M1
AP: 1=p.m., 0=a.m. (12 hour mode only)
H10: tens hours, H1: ones hours, M10: tens minutes,M1: ones minutes
Example: It’s 2:53:05 p.m. To set the clock using 12 hour mode, wait until nearly 2:54 and enter the
command (with the controller unlocked) *4100 1 0254 and unkey. Time your command entry so that
you unkey at 2:54:00 if you want to set the clock precisely.
Set Date *4101 M10 M1 D10 D1 Y10 Y1
M10: tens month, M1: ones month, D10: tens day, D1: ones day, Y10: tens year, Y1:ones year
Example: The date is April 1, 1991. To set the calendar, enter the command (with the controller
unlocked) *4101 04 01 91.
Set Day of Week *4102 DO
DO (day of week):
0 = Sunday 4 = Thursday
1 = Monday 5 = Friday
2 = Tuesday 6 = Saturday
3 = ednesday
Example: It’s Friday (thank goodness). To set the day of week to Friday, enter the command (with
the controller unlocked) *4102 5.
The current time of day can be played by users with the demo user command
below.
Say Time of Day [Demo Prefix] 9
5

Scheduler
The scheduler works with your existing five macro sets, the new clock / calendar,
and “setpoints” which you can program to tell the controller when to change over
to a new macro set. The automatic selection of macro sets by the scheduler is
identical to your manual selection using the Macro Set Select Control Operator
command.
You’ve programmed the clock above, and this section gives programming
information for setpoints.
There is room for ten setpoints which you can fill in as needed to arrange your
“schedule”. Each setpoint specifies certain information relating to the
changeover. The day of the week can be a specific day (Monday, etc.), weekends
(Saturday, Sunday), all weekdays (Monday through Friday), or every day of the
week. You can also optionally specify an nth day of the month - i.e. third Monday
of each month. The time for the changeover is defined by hours and minutes.
Finally, the macro set to be loaded at the changeover is specified in the program-
ming command shown below. Use the programming command below based
on the 12 or 24 hour mode you selected when setting the clock.
Define setpoint (12 hr mode) *420 S Nth DO AP H10 H1 M10 M1 M#
Define setpoint (24 hr mode) *420 S Nth DO H10 H1 M10 M1 M#
S: Setpoint 0-9. Ten setpoints can be programmed. To erase a setpoint, enter all zeros for the
setpoint and any macro set (like macro set 1, i.e. *420 S 0 0 0 0000 1).
Nth: The 1st, 2nd, 3rd, 4th, or ANY day of week of the month.
0 = ANY 1 = first 2 = second 3 = third 4 = fourth
DO (day of week):
0 = Sunday 5 = Friday
1 = Monday6 = Saturday
2 = Tuesday 7 = everyday
3 = ednesday 8 = weekdays
4 = Thursday 9 = weekends
AP: 1 = p.m., 0 = a.m. (12 hour mode only)
H10: tens hours, H1: ones hours, M10: tens minutes, M1: ones minutes
M#: Macro set # 1-5
Example: Select macro set #3 every weeknight at 11:00 p.m. Use setpoint #5. The clock is in 12
hour mode. Enter the command (with the controller unlocked) *420 5 0 8 1 11 00 3.
Be sure you have selected the format you want to use (12 or 24 hour) using the Time command.
You must define setpoints using the same format as selected for the time.
The following new Control Operator commands relate to the scheduler. The
currently selected macro set number can be read back. The scheduler can be
turned on and off, and the on/off status of the scheduler can be read back.
1 1-5 Interrogate Current Macro Set
1 1 S on Scheduler On†
1 2 S off Scheduler Off†
1 3 on/off Interrogate Scheduler On/Off

Female and Sound Effects Synthesized Speech
Thirty-two female words, 10 male words, and 8 sound effects are added to the
vocabulary list. In addition, five “run-time variables” can be programmed into
messages to play time and date related information as part of the messages.
The vocabulary additions along with their message editor codes are shown below
and in the programming summary.
Female
oh *800 twelve *812 good *834
one *801 thirteen *813 morning *841

HF Remote Base
A Kenwood TS-440S HF transceiver can be connected to the controller and can
be operated remotely through the repeater. Installation instructions for the
transceiver are shown later in this note. This section describes the commands
which relate to operation of the HF remote.
The HF remote base gets its own user command code prefix. The
programming command for selecting the user level HF Prefix is:
*5020 (prefix)
Example: Select HF remote base prefix as 1. Enter the command (while unlocked) *50201.
The Control Op can enable and disable the HF remote base:
107 HF Remote Base Enabled† HE
108 HF Remote Base Disabled† HD
The HF remote can be put into Receive Only, Receive/Transmit, and can be
turned Off by users. In addition, frequency, mode, and memories can be se-
lected. The user commands for these functions are:
Receive Only [HF Prefix] 1
Receive/Transmit [HF Prefix] 2
Off [HF Prefix] 3
Frequency Interrogate [HF Prefix] 8
Frequency Enter [HF Prefix] (10M)M*HT(O(h(t)))
Examples (assuming HF Prefix = factory default value of 1):
14.23 MHz = 1 14*23 3.89551 MHz = 1 3*89551
7.255 MHz = 1 7*255 21.3 MHz = 1 21*30
Bump Up 100 Hz [HF Prefix] 6
Bump Down 100 Hz [HF Prefix] 4
Bump Up 500 Hz [HF Prefix] 9
Bump Down 500 Hz [HF Prefix] 7
Bump Up 20 Hz [HF Prefix] A
Bump Down 20 Hz [HF Prefix] B
Example (assuming HF Prefix = factory default value of 1): Bump HF frequency up 100 Hz: 1 6
Scan Down Slow [HF Prefix] 7 1
Scan Up Slow [HF Prefix] 7 3
Scan Down Medium [HF Prefix] 7 4
Scan Up Medium [HF Prefix] 7 6
Scan Down Fast [HF Prefix] 7 7
Scan Up Fast [HF Prefix] 7 9
Scan Stop Carrier (key down VHF/UHF radio)
Example (assuming HF Prefix = factory default value of 1):
Scan up medium: 1 7 6. Stop scanning: key your radio.
8

Mode [HF Prefix] 1 (mode 1-4)
Mode: 1=USB, 2=LSB, 3=AM, 4=FM
Examples (assuming HF Prefix = factory default value of 1): USB = 1 1 1 LSB = 1 1 2
Memory [HF Prefix] 5 (00-99)
Note: Memories must be preprogrammed into the HF transceiver.
VFO A [HF Prefix] 5
Example (assuming HF Prefix = factory default value of 1): Select memory 54 which has been
preprogrammed into the radio. Enter 1 5 54. To return the HF radio to VFO A, enter 1 5.
Tone Panel CTCSS Regeneration (‘96 Only)
The existing Tone Panel programming commands are expanded to provide for
several modes of regeneration of the incoming tone. Previously, only a fixed tone
could be encoded. As a reminder, tone #1 must be programmed as encode
(unlocked, *5100 1) in order to regenerate.
*5101 39 Regenerate incoming tone only while mobile present
*5101 40 Regenerate incoming tone until repeater carrier drops
*5101 41 Regenerate incoming tone only while mobile present (lockout
others until repeater carrier drops)
*5101 42 Regenerate incoming tone until repeater carrier drops (lockout
others until repeater carrier drops)
Tone position 2 is encoded continuously during phone patches (reverse patches
and patches made by the mobile) in all four regenerate modes.
Example: We have four encode tones installed in positions 2-5. Encoder at position 1 should
regenerate the incoming tone only while the mobile is present, and the controller should not
respond to other incoming tones until the repeater carrier is allowed to drop. Enter the command
(with the controller unlocked) *5101 41
Autopatch Toll Restrict Enhancement
In order to better accommodate densely populated locations where area codes are
being split, five “Permitted Area Codes” have been added. These are entered as
messages (either Morse or speech), i.e. “1415”, ”301”, “1800”.
In addition, “local calls” can be defined as maximum seven or eight digit
(permitting “1”+ 7 digit calls while preserving 10 and 11 digit toll call
protection). The 7 or 8 is programmed as a one character message. See the
message list in Appendix C, Programming Commands
Don’t Answer Telephone For Two Minutes
A new Control Op command - “Don’t answer for 2 minutes” - makes it more
convenient to share the ‘85/’96 phone line with an ‘850 and modem. See
Appendix B, Control Operator Commands.
Interrogating Autodial Numbers
Telephone numbers stored in Autodial locations can be read out without dialing
the number, including from the phone. See Appendix A, User Commands.

Installation of the HF Remote Base
In addition to your RC-85 or RC-96 Repeater Controller, you need:
From Kenwood:
Kenwood TS-440S
IC-10 IC kit (Intel or equivalent 8251A, RCA or equivalent CD4040B)
You do not need the IF-232C level translator.
From ACC:
For the RC-96 only, Serial Port Board (available from ACC)
Connections
The interconnections between the controller and the TS-440S include transmit
audio, receive audio, push-to-talk (RC-96 only), and serial port for control. A
COS or squelch signal may be used but is not readily accessible from the radio.
Be sure to install the ‘96 Serial Port Board as indicated in the instructions
supplied with it to generate the Serial Out signal.
‘85 ‘96 TS-440S
Tx Audio Tx Audio AFSK IN
(J4-8) (LINK-6, green)
Link Rx Audio Link Rx Audio AFSK OUT or speaker jack

(LINK-4, orange) “From standby switch”
CX3 Serial Out Serial Input (ACC1 jack pin 3,
(J3-11) (CNTL RX-6, green) bottom pin)
For the RC-85 controller, DIP Switch 4 must be ON.
ith the controller unlocked, program an HF command prefix (*5020 prefix).
Assuming you are not using a COS, program the Link COS Logic Sense to “low
true” (*5410). Enable the HF remote base with the Control Op command (prefix)
107.
ith the HF remote turned on (see User Command summary), set link receive
level on the controller (‘96 = LRX, ‘85 = R2), and the mic gain on the TS-440 for
HF transmit level.

Miscellaneous Improvements
The following changes have been made in V5 firmware.
• Reverse patch mode 4 is added which places the caller directly on the air. The
caller can enter Touch-Tone # during the first five seconds to revert to mode 0
and be taken off the air for the remainder of the call. (# must be the first
Touch-Tone digit entered.) Otherwise, after five seconds, the Touch-Tone de-
coder switches to the receiver to give the mobile Touch-Tone control over the
radio-telephone interconnection.
• Control Operator command 110 causes a modulo 256 “keyup counter” to be
spoken, which can provide rough information about repeater usage. The counter
is cleared by the Control Operator Reset command.
• VHF/UHF remote base frequency readback can be inhibited when * is left out
as a decimal point.
• Loading autodial locations from the phone automatically extends the
telephone timer so the controller won’t hang up.
• Band units not present in your IC-900 “stack” can be locked out from selection
to avoid potential confusion. See Appendix C, Programming Commands.
• hen using the FC-900, Link 2 can be disabled if you have only one band unit
to avoid confusion. See Appendix B, Control Operator Commands.
• Bands can be swapped without Link 2 unit needing to be on.
• A band unit cannot be selected for both Link 1 and Link 2
• If Control Receiver COS becomes active while someone is controlling on the
phone, control is returned properly to the phone after COS becomes inactive.
• The cover tone is automatically disabled if a user manually selects full duplex.
• Spare audio is properly muted by a signal on the repeater receiver.
• The unlock timer has been changed from one minute to two minutes.
• The speech letter “S” can be included in the Patch Dialing Prefix to generate
Touch-Tone “*”.
• RC-96 controller Tone Panel only ... Control Operator commands 81 and 91
turn encode on and off (previously enabled and disabled decode only). The state
is stored in macro sets along with other setup information.
