LBI-39076B INSTALLATION

24-pin connector on one end, and a standard 24-pin

connector on the other.

To install the data bus cables, connect the IAM unit (if

present) first, then the Master GTI unit, and finally the

standard GTI units (from the lowest channel to the highest

channel). Plug the standard connector of the first cable

directly into the first unit, and the stackable connector of the

first cable directly into the second unit. Then plug the

standard connector of the second cable into the stackable

connector of the first cable (which is plugged into the

second unit), and the stackable connector of the second

cable directly into the third unit. Continue connecting the

cables in this way until all units are connected together.

Then, plug the PCM/Data bus termination plug into the

stackable connector of the last cable (which is plugged into

the last unit).

Figure 1 shows the standard routing for a typical ELI

system. Figure 32 shows the pin-out information for

PCM/Data bus cables.

Site Controller Computer

Two data cables must connect the Master GTI to the

Site Controller computer. Connect a 19B803826P1 cable

from the left female RJ-11-6 connector on the back of the

Master GTI, to Port 30 on the back of the Site Controller

computer. Connect a 19B803826P2 cable from the right

female RJ-11-6 connector on the back of the Master GTI, to

Port 31 on the back of the Site Controller computer. The

locations of Ports 30 and 31 on the back of the Site

Controller computer are shown in Figure 33.

11. IAM SOFTWARE

The 11th step to install the ELI option applies only if

an IAM was supplied. Record the software version number

marked on the software PROM in the IAM unit. If a

problem is later encountered with the equipment, the

software version number may be essential to help with the

diagnosis.

The location of the software PROM in the IAM unit is

shown in Figure 34.

Figure 34 - IAM Software Locations

The IAM software is stored in U23 in the IAM. A

sample label for U23 is shown in Figure 35. The actual

version number of the software supplied may be different

than that shown.
