Connecting a TMR coordinator - Verasys - LIT-12014293 - LC-SBH300-0 - LC-SBH300-0C - LC-SBH300-0LA - LC-SBHPNL-01 - Network gateway - SBH300 Smart Building Hub - 5.1

You can connect equipment over a MS/TP wireless network to the SBH300 with a TMR set to coordinator mode. You can connect up to two TMRs in Coordinator Mode to the SBH300. The first TMR connected to the System Bus of the SBH300 automatically resets to Coordinator Mode. When you connect a second TMR to the SBH300, you must manually set the TMR to Coordinator Mode. For more information about Coordinator Mode, refer to the Mode selection section of Verasys TMR Series Wireless Router Installation Guide (LIT-12014167).

1. Connect the TMR RJ-12 port to the SBH System Bus RJ-12 port.
2. If the System Bus RJ-12 port is already in use, or to connect a second TMR, use the System Bus (FC) four-pin terminal block.
   Note: The SBH300 provides power for the TMR on +15V pin of the System Bus (FC) connector. If the SBH300 is wired to other MS/TP devices, do not connect the cable’s shield wire to the four-terminal System Bus port. Leave the shield disconnected, or wire-nut the shield wires together and bypass the SBH300. For more information about wiring the System Bus terminal block refer to the Screw Terminal Blocks for Connecting the Bus Cable section of the Verasys BACnet MS/TP Communications Technical Bulletin (LIT-12012362) .
   Note: If the System Bus starts at the SBH300, connect the shield to earth ground. If the SBH is in the middle of the run, wire nut the shields together and bypass the SBH300.
