During installation take precautions to help ensure proper operation of the SA-
G+. Do not create loops, sharp bends or crimps in the cables. Use proper
terminations on all power cables.
Note: If the SA-G+ will be used in a vehicle, attach all cables to the
vehicle and equipment in such a way to reduce stress or wear
caused by vibration generated by moving vehicles.
The user can purchase the optional eight (8) pin external I/O connector for the
Enfora SA-G+ that can be used to interface with other devices. Enfora can
provide an optional cable and connector (Part #CAB1308). The user also has
the option of building his/her own cable. Table 2 describes the pin functionality
for this 8 pin I/O connector. Pins that are not planned for usage can be left open
without anything connected to them.
