Product Description
The Model 8322 RS-232 to RS-422/RS-485 Interface Converter allows
information exchange in full or half-duplex mode over two twisted pair
cables. This conversion is accomplished while maintaining optical
isolation between the ports. Dip switches are used to select RS-232 to
RS422 or RS-232 to RS-485 operating modes. The unit may be mounted on
our DIN rail system.
The Model 8322 has one RS-232 I/O configured in DCE mode enabling the
reception of data circulating on the receive pair (RS-422 or RS-485
side) or the transmission of data towards the RS-422 or RS-485 transmit
pair.
The Model 8322 includes TD and RD LED’s as well as a built-in power supply. The
power input is 110 V/60 Hz. All the inputs and outputs are via screw
terminals located on the top surface of the device.
A full complement of dip switches are provided to select operation mode, data rate, byte
format, master/slave configuration as well as pull up and pull down
resistors on all received data lines as well as terminal loads for
transmitters and receivers. The user also as the ability to configure
the grounding scheme for the four wire links.
