and is disabled by default. To enable the GPI-2, mount both the P1 and P2 jumper selection 
to 2/3 PIN and set the corresponding GPI function. When the external active input is 
disconnected for less than 3 seconds, the corresponding GPI-2 function is activated, and 
when the GPI-2 connection line is disconnected or open for more than 6 seconds, the GPI-2 
fault is reported.

Built in RS-485 repeater, the cable length can be extended to next device for 
another 1.2km.

RS-485 Network can be configured in closed loop for better communication 
reliability. The communication can switch direction to communicate with devices 
behind the failure point when there’s device failure, line break or line short circuit.

SCADA/HMI/PLC systems capable of Modbus RTU open protocol can communicate 
with ASD devices.
