GCM Batteries
Use NiMH (Nickel Metal Hydride) batteries - AA size. Minimum 2400 milli-
amp hours.
Software House recommends that you replace the NiMH (Nickel Metal
Hydride) AA size batteries yearly.
Caution: Risk of explosion if battery is replaced by an incorrect type. Dispose of
used batteries according to the instructions.
iSTAR Pro batteries are packaged separately and should be installed in the
battery backup sockets at the bottom of the GCM.
The unit is stored and shipped with the batteries disconnected so they will not
be drained while in storage. Connect the batteries as shown in the GCM
diagram that follows. If the batteries are installed with the power off, the reset
switch (S5) must be pressed after power is applied.
It is acceptable to install the batteries with the power on. However, if the
batteries are installed with the power on, you do not need to press the reset
switch.
NOTE
The batteries provide power to retain the volatile memory (clearances, activity,
etc.) data in the event of a power failure. The batteries do not supply enough
power for iSTAR Pro normal operations.
Diagnostic Session
A diagnostic session can be run either through ICU or with a terminal session
through P5. Turn on the diagnostic information settings using either ICU or the
HTTP connection to the iSTAR Pro.
1. Connect P5 to a COM port on a PC.
Use a straight through DB9F to DB9F cable.
2. Set the COM port to 115,200 baud, 8 data bits, None, 1 stop bit, Hardware
Flow Control.
3. Start a terminal session using an emulator such as HyperTerminal.
Dip Switches
DIP Switch S2 is factory set for RS232 on P6. Do Not Change.
DIP Switch S1 is factory set for RS232 on P6. Do Not Change.
DIP Switch S4 is used to control diagnostics, clear memory, and to display
card reads in hexadecimal.
NOTE
The diagnostic information causes overhead and should not be activated
during normal operation.
