CNI2 Operating and Installation Guide

Cellular Radio Module

The cellular radio module is manufactured by Motorola and will be either a g24-L (GSM) or c24
(CDMA). It is possible to remove and install a new module in the event that the original module
fails. Two small screws must be removed first, the radio pulled straight away from the board,
and the nylon spacers retained for later use. This type of operation is best performed within an
office setting, and even then only when absolutely necessary. The high density electrical
connector on the radio is delicate and can easily be damaged unless great care is taken during
insertion and removal.

SIM Card Socket

This connector holds the cellular radio SIM card for GSM-equipped models of the CNI2. SIM
cards are not required for CDMA radios.

Reset Jumper JP4

If it is necessary to perform a complete reset operation, use a small blade screwdriver or coin to
short out the two pins of JP4.
Caution:
A reset will cause all pulse data to be lost and the unit's time-of-day to be reset. This
will cause the CNI2 to call the data collection system to report a "Unit Reset" alarm.
When possible, first place a call to download accumulated interval data to the central
office prior to performing a reset.
Power Connectors J1 & J2
These connectors are intended for connection to power sources. Both connectors are identical
in function, and allow for the hot-swap of batteries without the loss of power to the CNI2 board.
