5.3. Device Connections to MCS-BMS-GATEWAY
MCS-BMS-GATEWAY6 Pin Phoenix connector for RS-485 Devices.
• Pins 1 through 3 are for RS-485 devices.
• The RS-485 GND (Pin 3) is not typically connected
• Pins 4 through 6 are for power. Do not connect power (wait until Section
3.4
).
5.4. MCS-MAGNUM Address Settings
The MCS-BMS-GATEWAY is connected to the MCS-MAGNUM via Ethernet . The Bacnet Device ID and the
IP address of the MCS-MAGNUM must be setup properly to enable successful communications between the
MCS-BMS-GATEWAY and the MCS-MAGNUM.
The MCS-MAGNUM BACNET DEVICE ID must be set to the address specified on the MCS-BMS-GATEWAY’s label.
The MCS-MAGNUM BACNET DEVICE ID can be verified and changed (with the proper authorization code)
Set the MCS MAGNUM to address as shown on label:
NOTE:
This BACNet Device ID will change depending
on the address that will be set on the ‘A’ DIP Switches.
