To make the connections to the module:
1. Pull the cables from the backbox or spacer, and then slide
them though the module’s frame.
Passive Customizable Module Connections and Jumper
The module connects to a passive room bus using an 8-pole
connector. It can also be daisy-chained with other peripheral
devices on same bus. The connector carries 5.5VDC power,
input, and output lines.
The module includes a jumper to activate and End-of-Line
resistor (EOL) when the module is last module on the passive
bus.

8-pole Passive Bus Connection Pinouts
To connect a passive customizable button module:
1. Slide the cables with their connectors through a module
frame.
2. If this is the last device on the passive room bus, move the
EOL jumper to the pins labeled EOL; otherwise, leave the
jumper in its default position (OFF). See the previous
figure, item 2.
Note:
EOL must also be configured in the system using the
