LBI-39076B INSTALLATION

You may use some other method. However, using the method described here assures that the supplied cables will be the correct length and the PCM/Data Bus will be as short as possible. (The PCM/Data Bus must not exceed 120 feet in length).

5. GTI SOFTWARE

The 5th step to install the ELI option is to make sure that the insulating paper tab on the battery (RAM backup) has been removed, and record the version number of all software on each board in each GTI unit. Each regular GTI unit has a Main board and a Processor board. One regular GTI unit is made into a Master GTI unit by adding a third board, the Interface board. Keep this information with this

manual for future reference. If a problem is later encountered with the equipment, this information may be essential to help with the diagnosis.

Main Board

NOTE

Revision-A Main boards do not support narrowband systems. If you have a narrowband system, you must use revision-D or later Main boards.

The Main board contains the GTI 552 and GTI DSP software at the locations shown in Figure 10. The first Main boards, identified by the manufacturer’s number 702-9588A, require different software than later Main boards, identified by the manufacturer’s number 702-9588D or E. The boards are referred to as revision-A Main boards and revision-D or E Main boards respectively.

Revision-A Main boards

CAUTION

Revision-A Main boards require version 1.x GTI 552 and GTI DSP software. Do not use version 2.x or higher GTI 552 or GTI DSP software with revision-A Main boards.

For a revision-A Main board, the GTI 552 software is stored in U63 and requires version 1.x software (where x = any number). A sample label for U63 is shown in Figure 11. (The actual version number of the software supplied may be different than that shown.)
