0.2 usn~ THE unit OPEFATItN MANUAL
This manual is divided into three major sections providing 1) operator
information, 2) progranner information, and 3) a group of appendices
and
tables for supplemental reference. Although operators will find
the unit as easy to use as a typewriter, familiarity with section 1
allows the operator access to numerous selectable features designed to
maximize personal comfort. To obtain full performance of the unit, the
progratlIlEr should be thoroughly familiar with section 2. Knowledge of
the many unit features enable the progranner to efficiently generate an
effective display for any application.
0.3 rnsrATJAT.lQN
The unit should be positioned on a steady surface and at a comfortable
level for the user. A space of at least three inches must be provided
at the rear of the unit to provide ease of access to the power SWitch.
care must be taken that magazines or other rrater ial do not fall behind
the terminal and iIIq?ede ventilation. The line cord must be connected
to a three connector grounded AC source of the proper voltage. An
environment Which is comfortable to the user will generally be
acceptable for the use and storage of the unit. Extremes of
temperature and humidity must be avoided. Camect the unit to mst
using a 25 pin communications connector, and verify the pin connections
in appendix 3.1.2. Turn on the power switch at the rear of the unit.
Power on is definitively indicated by illumination of either the "ON
LINE" or "LOCAL" lamp on the keyboard. The unit will perform the power
up
self tests and beep when ready. After a one minute warm up period
for the display, the cursor should appear in the upper left position of
an otherwise clear screen. The cursor is the blinking rrarker which
indicates the position on the screen for the next character to be
displayed. If any other display appears, refer to Section 3.2. Turn
to section 1.3 and select the set up features appropriate to yoor
particular application.
~: The unit warms up with the display at a reduced size. During
warm up, the display area will expand over a period of approxinately 15
secorrls to fill the entire screen. Please do not be alaored at this
warm up procedure as it is norrral on each unit.
'" .4 MAINTENANCE
Extemal surfaces should be kept clean with the use of a mild soap or
detetgent solution on a damp cloth. Organic solvents must not be used.
No other forms of preventive rraintenance need be performed.

SEC'ION 1.0 OPEPA'lPR INFOmATION
1.1 IND.LCA'lPRS
1.1.1
1.1.2
1.1.3
In addition to alphanumeric and gr~hic information displayed on the
screen, the lD1it provides visual information via 7 lamps on the
keyboard. Either the ON LrnE lamp or the LOCAL lamp will be lit
whenever the lD1it is cperationa1. ON LINE signifies that characters
typed at the keyboard will be transmitted to the host. lOCAL signifies
that characters typed at the keyboard will be acted upon locally, but
not transmitted to the host. While in local Irode, the lD1.lt will not
receive or process data sent by the host. Altemate flashing of the ON
LINE and LOCAL lamps indicate that the operator has sent the "XOFF"
code to the host, having typed Centrol S, or NJ SCRCLL. In most
applications, receipt of XOFF will cause the host to susp:!nd
transmission to the lD1it lD1til the code XON is received. (See Section
2.2.) The alternate flashing raninds the operator that the host is
awaiting reactivation.
KBP lOCKED
Illumination of this indicator Signifies that the transmit buffer is
full, and no more characters will be accepted from the keyboard. Tlus
condition nay occur if the host has prevented the lD1it from
transmitting, or a fast typist is using the unit at a low transmit
sp:!ed, such as 75 baud. The locked condition nay be cleared by
entering and exiting SET UP mode, provided that the original condition
which caused the keyboard to lock (i.e., XOFF from the host) is also
cleared after exiting SE'lL-UP. If the original condition ranains, the
keyboard will very likely lock again lD1til the limiting condition is
cleared.
L1. L2p L3p IA
These four lamps are normally controlled by the host, and the
significance of their status should be included within local procedures
documentation. They are used umer progran control to notify the user
of a certain progran condition or status. (For rrore data, see Section
2.7.27.) In addition, L3 illuminates whenever the unit is in insertion
mode (see Section 2.7.54).
JlC<DUSl'IC INDICA'lPRS
Keyboard click is produced electronically and may be turned off or on
at the discretion of' the operator in SET UP mode B. When enabled, the
click .will be generated for each key depression which causes a coc;le . to

1.1.4
Page 4
be transmitted. Two short "beeps" are sounded when the unit is first
turned on and the power up self test is completed. A "beep-beep" is
also sounded in response to the bell code from the host, and whenever
the operator types to within eight character positions of the right
margin when the margin bell feature has been enabled. A series of ten
beeps upon power up, or when a recall (Section 1.3.9) operation has
been initiated, signifies that an intemal error has occurred while
attenpting to recall the SET UP features as they were last saved. If
this corrlition should occur, the operator must correct the SET UP
features and perform a save cperation. See Section 1.3.l~.
'lUBE SAYER
When the unit has been inactive for 9 minutes, i.e., m transmission or
reception has occurred, but power is applied, the screm will blank
automatically to prolong the picture tube life. When new data is
received, or the operator depresses any key, the screm is irrrrediately
restored. The key which restores the display is not transmitted. The
tube saver feature is not active whenever the operator is in Set Up
mode and may be selected or disabled by a progrannab1e switch in SetUp
Mooe C.
1.2 KEYBOARD
The unit keyboard supports three key rollover which allows extremely
fast typing sp:ed and keystroke overlap. With three key rollover, if
three keys are depressed, the terminal will process the first 2 keys in
the order in which they were depressed and process the third key as
soon as either of the other two are released. Except for this feature,
the unit keyboard functions exactly as does a typ:writer. The proper
code associated with the key legend is transmitted each time a key is
depressed. The shift key is used to send the upp:r case/shifted
characters, and CAPS LOCK forces all alphabetic keys to be transmitted
in upp:r case independent of the shift key. Nm alphabetic keys must
be shifted to obtain the upp:r case legend even if the caps lock is
depressed. Keys which flll'X!tion other than to send the code assoc iated
with their legem are described below.
Please refer to Figure 1.2 on following p:lge.
