Table 8-17 SEAR IIi Module User Interface
Component
Function
Identification Labels For
User Programmable LEDs
T01 through T16
Each label corresponds to a User Programmable LED and may
be inscribed to identify a user-defined event.
ECH SVC LED
Flashes red until SEAR IIi is initialized.
ECH SVC Push button
Not used
POWER LED
Lights green when power is applied to SEAR IIi
HEALTH LED
Flashes green if backup battery output is within the acceptable
voltage range.
Flashes yellow if the backup battery is below minimum
acceptable voltage.
Remains off when SEAR IIi is inoperative.
User Programmable LEDs
T01 through T16
Each LED illuminates to Identify the occurrence of a user-
defined event.
LED color (red, green, or yellow) is determined by
programming.
AUX J1
Female DB-25 connector for RS232/RS422 serial interface to
radio or telephone modem
USER J2
Female DB-9 connector for RS232 serial interface to printer or
PC
J3
12-pin male I/O connector, providing the following functions:
Two isolated digital inputs (DI1, DI2)
Each input may be used to monitor up to 120V AC/DC
Two isolated contact relay outputs (RLY 1, RLY 2)
Temperature monitor input (TEMP)
Battery monitor input (BATT MON)
8.3.8 A80435 External Configuration Device (ECD)
The ECD is a factory-installed plug-in device on the GCP5000 (GCE) backplane (see Figure
8-12) that stores the module configuration file (MCF) and the application program for the
GCP5000 (GCE). The CPU Module copies the MCF from the ECD, as it is used for vital system
operation.
WARNING
IF AN ECD IS REPLACED WITH AN ECD CONTAINING A DIFFERENT
MCF, THE GCP5000 (GCE) WILL COPY THE NEW MCF INTO THE
FLASH ON THE CPU MODULES AND SET THE SYSTEM BACK TO
DEFAULT VALUES.
