Operators Display
The Operators Display (OD) is the main interface to system. The display
provides the user with all necessary switches, keys and annunciation points to
maintain and monitor the system. Alarm, supervisory and trouble conditions are
indicated by dedicated LED's and the internal sounder. The system's operating
status is shown on the alphanumeric display. LED annunciation is also provided
for AC power, PreAlarm, (2) signal circuits, City Tie connection and Bypass.
The alphanumeric keypad provides user access for programming and password
entry.
The alphanumeric display contains a 4 x 40 character backlit display. To regulate
the contrast of the alphanumeric LCD display, adjust the potentiometer R29
located (solder side of the display board - lower left hand corner) - see drawing D-
W1146). The card location identification number is " 0 " (see above Table I-3).
Installation
Diagram
Refer to (drawing # B-W471) Wiring, IF632 Analog Addressable System. The
34 pin ribbon cable (p/n 71158) interconnects the OD to the bus driver module
(J11 connector).

CPU Module
The CPU module (or microprocessor module) contains the system operating
firmware and non-volatile memory. It provides all the system memory and
processing functions as well as providing the local/remote communications and
supervision. System field programming, via a laptop PC link, is accomplished
utilizing the P2 interface. The CPU module jumper settings are preset at the
factory and do not require any field programming. Do not place any jumpers on
the module.
Baud Rate
Setting
The settings of DIP switch SW1, regulates the system's baud rate. The switch
settings are preset at the factory; see SW1 default settings table.
The module contains a serial communications port for serial device interface
(Isolated RS-232 Card). To install, the U18 IC must be removed from its socket
and replaced with the interconnecting cable from the Isolated RS-232 Card.
