Black Box IC520A-M video converter

1- DB25 male, 1- 4-screw terminal block The Async RS-232 to 2-Wire RS-485 Converter provides excellent versatility in a compact package. Requiring no AC power or batteries for operation, the Converter
supports asynchronous RS-232 data rates to 115.2 kbps over one unconditioned twisted pair in half-duplex mode. The line is automatically turned around from receiving to transmitting upon the beginning of receiving of RS-232 data. No RS-232 control signal is
needed to turn around the line.

The Converter is equipped with either male or female DB25 connectors for RS-232. For the twisted pair connection, you can choose either a 4-wire terminal block or an RJ-45 female connector. Silicon Avalanche Diodes provide 600 watts per wire of protection against harmful data-line transient surges.
