Black Box RS-232 to RS-422 Converter - 1 x DB-25 RS-232 , 1 x RS-422 Terminal Block - External
- Transmits data up to 4000 feet (1219.2 m).
- Full-duplex operation over 4-wire lines.
- Async (data leads) only.
Our popular RS-232 to RS-422 Converter provides reliable conversion at speeds up to 64 kbps. You can transmit data up to 4000 feet (1219.2 m) on the RS-422/485 interface - over 4-wire lines in full-duplex operation.

In RS-485 mode, select either RTS or DTR to enable the driver. Or set the driver so that it's always enabled.
The converter features DIP switches instead of DIP shunts for easy setup. It's intended for use with data signals, so if you need a converter that supports handshake and clocking leads, our techs recommend one of the RS-232 to RS-422/RS-449 Converters (IC456A-R5, IC456C-R5) in Related Items.$293.01 -
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).
