6 Wireless Transceiver Installation and Operation Manual
2. Program the Wireless TRV System ID using one of the following methods:
• Program the System ID by Connecting the Wireless TRV to the MSI Hub
NOTE: When programming the System ID with the MSI Hub cable, do not connect an external power supply to the TRV.
Power must be supplied by the MSI Hub.
a. Ensure the MSI Hub has been powered‐on and has already been programmed with the System ID. Observe the MSI Hub
status LEDs (1). If the status LEDs are not blinking, or are blinking only once every 15 seconds, a System ID has been
programmed. If the LEDs are blinking rapidly (once per second), a System ID has not been programmed.
b. Connect the provided black MSI RJ11 communications cable (2) to the programming connection on the MSI Hub (3) and
Wireless TRV (4).
The black MSI RJ11 communications cable MUST be used when connecting the MSI Hub to the
Wireless TRV. Using any other cable may result in damage to the MSI Hub and/or the Wireless TRV.
c. Observe the red and green status LEDs (5). When the LEDs stop blinking, the TRV is programmed and ready to install.
NOTE: If the red LED remains lit for more than 20 seconds, the Wireless TRV has already been programmed with a
System ID. The System ID must be cleared before proceeding. Refer to "Clearing the Wireless TRV System ID" on page 7.
d. Disconnect the Wireless TRV from the MSI Hub. Repeat this procedure for any additional Wireless TRVs, and then
continue with "Mounting the Wireless TRV" on page 8.
• Program the System ID Wirelessly using the MSI Hub
a. Ensure the MSI Hub has been powered‐on and has already been programmed with the System ID. Observe the MSI Hub
status LEDs (1). If the status LEDs are not blinking, or are blinking only once every 15 seconds, a System ID has been
programmed. If the LEDs are blinking rapidly (once per second), a System ID has not been programmed.
