FAQ
Q: Can the termination resistors be disabled?
A: Yes, both transmitter and receiver terminations are jumper-selectable and disabled by default.
Q: Does it support both RS-422 and RS-485 simultaneously?
A: The device supports either RS-422 or RS-485 over the four-wire interface; full-duplex operation is available on both protocols.
Q: What is the maximum recommended cable length?
A: For RS-485, up to 1,200 meters at 100 kbps; for RS-422, up to 1,500 meters at 10 Mbps depending on cable type and network topology.
