PRODUCT OVERVIEW
This DIN rail mountable converter optically
isolates and converts unbalanced, full or
half-duplex RS-232 signals to balanced RS-422/485
signals at baud rates up to 115.2 Kbps. In addition to
optical isolation, the unit has surge suppression on the
RS-422/485 lines. FeaturingAutomatic Send Data Control
circuitry, it does not require special software control
of handshake signals in RS-485 mode. The removable
terminal blocks for power and RS-422/485 signals make
wiring easy. It is powered by a supply voltage of 10
to 48 VDC which is isolated from all data and signal
ground lines. Configuration is made easy with a 12
position DIP switch on the bottom of the converter.
