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.
