General Product Information
The 485OI9TB converts unbalanced, full-duplex RS-232 signals to balanced full-duplex (4-Wire) RS-422/485 or half-duplex (2-Wire) RS-485 Signals. It also provides 1500 Volts RMS optical isolation of the data lines and ground between the RS-232 and RS-422/485 signals.
The RS-232 port has a female DB9 connector with Pin 3 (TD), Pin 2 (RD), and Pin 5 (Ground) passed through. The RS-422/485 port has a 6 position terminal block. The RS-232 side of the converter derives its power from the DTR (Pin 4) and the RTS (Pin 7) lines. One or the other must be raised to power the RS-232 side. The RS-422/485 side is powered by a 12 VDC power supply which is purchased separately.
