User Guide P a g e 6 Revision: 1.03
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.
