Black Box IC1473A-F-ET RS-232 to RS-422 Interface Converter, DB9 to Terminal Block

Black Box IC1473A-F-ET Async RS-232 to RS-422 Interface Converter

The IC1473A-F-ET RS-232 to RS-422 Interface Converter is a port-powered two-channel RS-232 to RS-422 converter that operates in extended temperature environments. It converts TD and RD RS-232 lines to balanced RS-422 signals. The converter can be powered from the RS-232 handshake lines, DTR and RTS. If port-powering the unit, at least one of these handshake lines must be present, but can be in any state. It can also be powered externally on the terminal blocks. The RS-422 driver and receiver are always enabled. For DB9 equipment, if the peripheral operates on the RS-422 signal, use only one DB9 converter. But if the transmitting and receiving equipment only operates on RS-232, use two converters. All provide 115.2-kbps speed for distances up to 4000 feet (1219.2 m).

To satisfy the requirements of some software packages, the RS-232 handshake lines are looped back (tied together). RTS is connected to CTS, and DTR is connected to DSR and DCD.
