CAT5 (or equivalent) cable connecting to the next TH Module in the cascading configuration.
This port may be used to link to a TH Module or to plug in an APC terminator.
Adding power supplies
Warning: The first time a TH Module receives power, it requests a unique identification address from the Main Module. It uses this address to communicate with the Main Module. If the TH Module is not part of the system when it receives power for the first time, it cannot ensure that its identification address is unique, and communication problems may arise.
To avoid communication problems, connect the TH Module to the Main Module or to a TH Module that is part of the system before connecting a stabilized power supply to the 24 Vdc Input.

Connect the TH Module to the system.
Add a stabilized power supply (AP9505i) where needed.
If the system includes beacons, or devices attached to the +12 Vdc or +24 Vdc Voltage Output connector, attach a stabilized power supply (AP9505i) to the 24 Vdc Input of every third TH Module.
If the system does not include any beacons or voltage output connections, connect a stabilized power supply (AP9505i) to the 24 Vdc Input of every tenth TH Module.
