The U60 network interface expansion modules enable a controller or computer to communicate with LON networks via USB.


The compact devices are housed in DIN 43880 2TE-compliant enclosures. The U60 TP-1250 model is an interface to LON/IP TP-1250 and LON TP1250. The U60 FT model is an interface to LON/IP-FT and LON-FT. Both are compatible with OpenLDV 5 and with hosts implementing the LON/IP stack which provides source code for LON/IP and LON-compatible protocol stacks.

The interfaces facilitate communication with everyday devices like pumps, motors, valves, sensors, actuators, and lights for process control, building automation, energy management, transportation systems control, and telecommunications equipment management. Tx and Rx LEDs indicate LON packet transmission and reception. An on-board Status or Service LED (see specifications) provides a visual indication of device status; status is also communicated to the host via the USB interface enabling the host controller to monitor Status (TP1250 model) or provide a network Service indicator (FT model).
