8. GTI INTERFACE BOARD MOUNTING

The 8th step to install the ELI option, is to make a Master GTI from a standard GTI by adding the GTI Interface board. Each standard GTI contains two printed circuit boards, mounted as shown in Figure 27. A third board, the GTI Interface board, is added to one GTI unit at a site, making it the Master GTI.

PROCESSOR

BOARD

MAIN

BOARD

After the cover has been removed, add the GTI Interface board as follows:

1.Remove the five screws (don't throw them away) holding the GTI Processor board, and replace them with five screw-in standoffs supplied with the GTI Interface board.

2.Carefully position the GTI Interface board above the GTI Processor board, so that the 14 pins of P1 on the GTI Processor board line up with the 14-pin socket on the under side of the GTI Interface board, and push the GTI Interface board down to the standoffs.

3.Fasten the GTI Interface board to the standoffs using the five screws removed in step 1.
