Terminal, shown in Figure 1-1, is a smart,
editing terminal designed for user
convenience. It can be used in either the
Conversational or Block mode of operation.
The non-volatile memory retains: the desired
set-up configuration, the information in the
16 programmable Function Keys (shiftable to
32), and the 6 Programmable Edit Keys
(shiftable to 12). All the terminal set-up
functions are soft-setable from the keyboard.
Function keys and Edit keys can be
programmed by the host or from the
keyboard. For added user convenience, the
ADM 12 offers three display memory
configurations: 24 lines by 80 characters, 48
lines by 80 characters, and 24 lines by 158
characters. The ADM 12 is also
ergonomically designed for maximum user
comfort. Its features include: a tilt and swivel
monitor with positive detents; a low-profile,
user-friendly,
DIN standard keyboard; a six
foot long coiled keyboard cord. Designed for
speed and versatility, the ADM 12 is ideal for
most data terminal applications.
1.2 OPERATIONAL DESCRIPTION
The ADM 12 is used to enter, display, print,
and send asynchronous data. It is also used to
receive, print, and display data from an
auxiliary device such as a host computer. Its
most frequently liaed application is one in
which an operator interacts in a two-way
communication with a host computer.
However, in some applications the data
transfer may be unidirectional either from the
ADM 12 to the host or from the host to the
ADM 12.

1.2.2 Primary (Modem) and
Auxiliary Ports
The ADM 12 comes standard with two ports:
the RS-232C Modem Port and Auxiliary Port
1-2
which are located at the back ofthe terminal.
The Modem (lIO) Port is the link, or interface,
that handles the flow of data in both
directions between the ADM 12 and the host
computer.
The Auxiliary Port permits the use of an RO
(Receive Only) printer when hard copy of
data is needed.
1.2.3 Set-Up Mode
The ADM 12 features a non-volatile Set-Up
Mode which allows the terminal parameters
to be selected through commands from the
keyboard or host. These parameters,
including baud rates, word structure, cursor
type, communications control, and operating
modes, can then be "saved" in memory, and
retained when power is shut off.
1.2.4 Programmable Function and
Edit Keys
The ADM 12 has sixteen programmable
Function keys (shiftable to thirty-two) and six
programmable Edit keys (shiftable totwelve).
The information user-programmed into these
keys can be saved in non-volatile memory.
1.2.5 Power Requirements
The ADM 12 can accept 115 VACor230VAC
+/ - 10%, 50 or 60 Hz. The voltage is factory set,
and must be specified at the time of order.
1.3 SPECIFICATIONS
The ADM 12 specifications are listed III
Table 1-1, page 1-4.
1.4 ADM 12 WORD STRUCTURE
The ADM 12 transmits serial asynchronous
data in a 10 bit format in the sequence: one
start bit, seven or eight data bits, one or no
parity bit, and one stop bit. Parity selection
(odd,
even, or no parity) is permitted only with
a seven bit data word. If an eight bit data
word is selected, then bit eight can be
designated to be either 1 or O. Parity selection
and the value of bit eight are defined via Set-
Up Mode.

____ LEAR SIEGLER, INC.
DATA PRODUCTS DIVISION
The received data shall be forma tted the same
as the transmit data. The word structure,
baud rates, and other communications
characteristics are established via Set-Up
Mode selections.

INSTALLATION
2.1 INITIAL PREPARATION
The space-saving design of the ADM 12 has
proven to be beneficial for almost every
terminal site. Its small size is ideallysuitedto
those work environments where physical
space is limited.
The physical dimensions of the ADM 12 are
shown in Figure 2-1, page 2- 2. The basic
requirements for installation are as follows:
• Table or desk mounting
• Standard three-pronged 115-volt (230-
volt) A.C. power outlet.
• Cableconnection to the computer, data set
or modem; serial printer, or other
auxiliary device. If connectionto a remote
computer
is desired, a modemor data set is
usually required.
Allow the ADM 12 to adjust to
severe
changes in the environ-
ment before applying power. This
will reduce
the possibility of
internal condensation, which
could impair its operation.
2.1.1 Line Voltage Selection
The ADM 12 is shipped ready to operate at
either 115-volt or 230-volt AC as specified on
the purchase order. Contact your authorized
Lear Siegler maintenance personnel if the
operating voltage needs to be changed.
2-1
2.1.2 Set-Up Mode Preparation
The operating configurations of the ADM 12
are controlled by firmware "switches" and
have been pre-set at factory to the default
conditions as indicated by "*,, in Table A-I,
page A-I of the Appendix. The operating
configurations are displayed on the status
line when the Set-Up Mode is entered.
There aretwo levels ofSet-Up Mode: operator
convenience and supervisor set-up.
Operator Convenience set-up functions
are
characteristics that relate to operator comfort
or preference. The S:upervisor Set-Up
functions include all of the feature selections
available to the operator, as well as those
functions useful to the person programming
the system (see paragraph 3.2, page 3-1).
Normally, the Supervisorset-upfunctions are
selected when the terminal is installed, or a
new peripheral device is attached. Table A-
I, page A- 1, describes the Set-Up functions
which can be selected for both modes.
The Set- Up functions can alsobedownloaded
from a
host computer, as described in Table
A-2, page A-3 of the Appendix.
Parameters of the host computer must be
determinedbefore the terminal can be used. If
changes need to be made to the Set-Up mode
functions, refer to
Section 3.1, page 3-1.
2.1.3 Keyboard Plug-In
Before applying power to the terminal, plug
the keyboard coiled cord into the connector on
the back of the monitor. Refer to Figure 2-2,
page 2- 3 for connector location.

The ADM 12 monitor can be tilted and
swiveled topositionitin the optimum viewing
angle for the operator. Adjustments can be
made by pushing down from the top of the
monitor. "Clicks" heard, as the monitor is
adjusted are from the positive detent
mechanism, which holds the monitor
securely in the desired position.
The keyboard may be tilted for maximum
operator comfort. Simply turn down the two
feet located
under the rear of the keyboard
housing, if desired.
2.2 INTERFACE INFORMATION
The ADM 12 may be cableddirectlyto a local
computer,
serial printer (or other auxiliary
device), or it may be connected via telephone
data lines to a remotely located computer.
Remote
computer connections require the use
of a modem or data set. Figure 2-3, page 2-
4 shows a typical ADM 12 application.
Figure 2-2, page 2-3 shows the rear panel
locations of the interface connectors.
Figures 2-4 and 2-5, pages 2-6 and 2-7
show the logic associated with these
interfaces.
2.2.1 RS-232C Interface
The Primary (Modem) Port RS-232C Interface
provides the signals and levels associated
with RS-232C, allowing direct connection to a
computer or modem. The maximum
permissable cable length is 50 feet for RS-
232C
applications.
2.2.2 20mA Current Loop Interface
(Option)
The ADM 12 can as an option be configured
for 20mA Current Loop operation using the
Primary (Modem) Port. The current loop
interface signal levels allow cable lengths of
up to 1000 feet. The maximum baud rate for
current loop operation is 9600.

2.2.3 Auxiliary Port Interface
The Auxiliary Port is used for connecting an
RO (Receive Only) serial printer or other RO
device to the terminal using RS-232C signal
levels (refer to Figure 2-4, page 2-6).
Note
The peripheral device that is
attached
to the Auxiliary port
must operate at the same baud
rate as the communication line.
2.3 INSTALLING THE ADM 12
1. Check the ON/OFF switch on front of
unit. Refer to Figure 2-2, page 2- 3 to
ensure that it is set to OFF.
2. Connect the data interface cable(s) to the
terminal using the appropriate interface
information (paragraph 2.2, page 2-
2).
3. Plug the power cord into a grounded AC
outlet of the proper voltage.

2'.4 POWER TURN-ON
1. Set the ON/OFF switch on the front of
the unit to ON (referto Figure 2-2, page
2-3). A power on "beep" should occur
within two seconds.
2. Wait approximately 20 seconds for the
unit to warm up. The cursor should
appear in the HOME position.
3. The Self-Test message " OK" should
appear in the upper left corner and the
terminal will sound the audible alarm.
4. If the Self-Test message and the cursor do
not appear, turn off the ADM 12 wait 15
seconds and apply power again. If the
message and cursor still do not appear,
