Isolated Serial Converter
485OI9TB
Model 485OI9TB is a basic, isolated converter. It converts unbalanced, full
duplex RS-232 signals to balanced full-duplex (4-wire) RS-422/485 or half-
duplex (2-wire) RS-485 signals.
The converter provides 1,500 Volts RMS optical isolation of the data lines
and ground (and connected devices) between the RS-232 and RS-422/485
signals. RS-232 port has a female DB9 connector. RS-422/485 port has a
6-position terminal block.
The RS-232 side of the converter draws power from the handshake lines
(DTR, RTS). At least one handshake line must be asserted (raised high)
to power the RS-232 side.The RS-422/485 side must be powered by an
external 12 VDC power supply (sold separately).
