Black Box RS232 to RS-422 Interface Bidirectional Converter - 1 x DB-9 RS-232 , 1 x RS-422 Terminal Block - Internal
- RS422 pin-outs match an SMPTE video standard-compatible controlling device.
- For DB9 equipment, if the peripheral operates on the RS422 signal, use only one DB9 converter. But if the transmitting and receiving equipment only operates on RS-232, use two converters.
- Provides 115.2-kbps speed for distances up to 4000 feet (1219.2 m).
