Product Description

The Model 8323 RS-232 to RS-422 Interface Converter allows information exchange in full duplex mode over two twisted pairs. It converts RS-422 signals to RS-232 signals, bidirectionally, on the DIN rail mounting system. This conversion is accomplished while maintaining optical isolation between the ports. Model 8323 allows for the extension of RS-232 links to a maximum limit of 3300 feet or 1 km at any data rate up to 115.2 KBPS.

The Model 8323 includes TD and RD LED’s as well as a built-in power supply. The power input is standard for 110 Volts/60 Hz or 220 Volts/50 Hz as an ordering option. The inputs and outputs are via screw terminals located on the top and side surface of the device.

A full complement of dip switches are provided to select pull up and pull down resistors on RS-422 receive 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.
