WIRING BAS TO GATEWAY AND THEN GATEWAY TO TEMPTRAC:
Each gateway has 3 connection points.
The 6 position terminal block contains connection for power and MODBUS RTU (going to heaters).
The Ethernet port is for configuration, BACNET IP, or MODBUS TCP.
The 3 or 2 pin terminal is for the BAS interface: BACNET MSTP, or LONWORKS.
Power Connection:
Gateway power supply, 6 position tePWR, -PWR.
Use supplied wall wart style power supply. 15VDC. Do not power other devices with same power supply.
If power adapter has not already been connected, cut and discard the connector on the end, strip and
terminate the power adapter in the proper terminals. Verify polarity. If another supply is to be used, it must
be isolated. Do not use 24VAC power from heater.
Gateway Connection to Heaters:
Wiring from Gateway to the heaters, use twisted pair wire.
Connector on the
orange dongle adapter that is on the end of a 8” cable plugged into the back of the
TempTrac.
The wiring is standard 2 wire RS-485 wiring. You will connect all devices together in a daisy chain. We
recommend the gateway to be at the start of this connection.
