Installing UCM Communication Cards
in a BCU (BMTS)
You can install a card in any of the three modules on the BCU.
nCAUTION
Hazardous Voltage!
Turn off power at the BCU before installing the EIA-232 card. Failure to
turn off power before servicing may result in human injury or damage
to equipment.
To install a UCM communication card:
1. Align the card with the electronic components facing toward the bot-
tom of the BCU, and then slowly insert the card into the module at a
45-degree angle until the card is seated.
2. Slowly move the card from the 45-degree angle to 0 degrees (horizon-
tal), leaving the card perpendicular to the BCU logic board.
3. Secure the card using the two clips on each side of the module.
For an illustration of how to install a UCM communication card, see
Figure 99 on page 227.
