Wiring
Wiring the Gateway to the Chillgard RT
The Chillgard RT can be used to power the gateway from its 12V supply by connecting J14 terminals 1 (+12V)
and 3 (GND) to the gateway's terminal block at terminals TB:5 (POWER) and TB:6 (GND) as shown in Figure 1.
For RS-485 communications, connect J15 terminals A (+) and B (−) on the Chillgard RT to the gateway's terminal
block at terminals TB:1 (A) and TB:2 (B) as shown in Figure 1. Additionally, a jumper wire must be placed on the
gateway's terminal block between terminals TB:1 (A) and TB:3 (Y). Another jumper wire must be placed between
terminals TB:2 (B) and TB:4 (Z). as shown in Figure 1.
Wiring the Gateway to the BACnet MS/TP Network
The RS-485 A terminal on the gateway is configured for BACnet MS/TP. A jumper wire must be placed between
terminals TB:1 (A) and TB:3 (Y). Another jumper wire must be placed between terminals TB:2 (B) and TB:4 (Z).
Table 1 describes the XLTR-1000's RS-485 signals.
