- Connect the TMR to a compatible Field Controller using the FC Bus RJ-12 connector. This connection provides both power and communication to the TMR.
- Alternately, connect the + and – screw terminals on the TMR to the MS/TP RS485 + and – connections on the MS/TP controller and connect the 9-24VAC/VDC and GND screw terminals on the TMR to a compatible power source, see Figure 2.

Note: See Verasys BACnet MS/TP Communications Technical Bulletin (LIT-12012362) for more information.

Note: When connecting to the System bus, it is best practice to hard-wire the SBH200 to the VZC100.
Figure 4. TMR wired to VEC100 controller
Note: VEC controllers do not have an RJ-12 plug for their Zone Bus. This requires you to discretely wire the controller to the TMR. Connect the TMR + and - signals to the Zone Bus connector and TMR PWR/COM signals to the Sensor Bus connector. Alternately you can connect the PWR and COM to the 24V-OUT terminals.
