The BASgatewayLX is housed in a metal case that mounts on 35-mm DIN-rail and it is powered from a 24 VAC/VDC (± 10%) source. Its half-wave rectified power supply allows sharing of power with other half-wave devices.

The optically-isolated serial port allows for connection to either 2-wire or 3-wire EIA-485 networks using a removable 5-pin terminal block. Up to 30 EIA-485 Modbus devices can share the serial bus at data rates between 2.4 and 115.2 kbps. Internal jumpers allow flexible bias and termination options. They can be removed for mid-span installations.

The Ethernet port offers a shielded RJ-45 connector. Through auto-negotiation and Auto-MDIX, it automatically matches connections to the attached equipment. Therefore, either CAT5 straight-through or crossover cable can be used to attach to the BACnet/IP or Modbus TCP network at either 10 or 100 Mbps speed.

A resident web server allows for commissioning, and troubleshooting via a standard web browser. A reset switch is provided for returning to the factory default IP address. LED indicators provide communication status on both the Ethernet and serial ports.
