This Web-based LAN to RS232\/IR\/Relay server supports WEB GUI configuration, making it easy to manage relay ports and IR commands remotely.
\nRS-232: Pin 5 is GND, Pin 6 is received (RXD), Pin 7 is the transmit (TXD);<\/p>\n
RS-422: Pin 1 (RXD+), Pin 2 (TXD+), Pin 3 (RXD-), Pin 4 (TXD-), Pin 5 (GND);<\/p>\n
RS-485: Pin 1 (RXD+) and Pin 2 (TXD+) should be short connected as D+, Pin 3 (RXD-) and Pin 4 (TXD-) short connected as D-, and Pin 5 still is GND<\/p>\n
