3.2.1 Connecting BACnet GW-3 to a High Speed NFN Network
Control Module
• Use a HS-NCM-W for a twisted pair wire connection.
• Use a HS-NCM-SF for a single mode fiber-optic cable connection.
• Use a HS-NCM-MF for a multimode fiber-optic cable connection.
Connecting the BACnet GW-3 to an HS-NCM-W/SF/MF allows the gateway to communicate with
devices on a high speed NFN network. Connect an BACnet Gateway-3 to a High Speed Network
Control Moduleusing either of these methods:
USB to USB Cable Connection
Connecting the BACnet GW-3 to an HS-NCM-W, HS-NCM-SF or HS-NCM-MF allows the
gateway to communicate with devices on a high speed NFN network. Connect the cable between
the USB “A” port on a BACnet GW-3 board and the USB “B” port on an HS-NCM-W, HS-NCM-
SF or HS-NCM-MF. Or, connect the cable between the USB “B” port on a BACnet GW-3 board
and the USB “A” port on an HS-NCM-W, HS-NCM-SF or HS-NCM-MF.
