These surface mount boards are designed around the LTC490 and the LTC485 chips. They connect in-line with the PC com port to provide signal conversions from the RS232C to RS422 differential line signals.
The boards, measuring 1.4" sq. convert the TX and RX signals providing 4-wire (RS422) and 2-wire (RS485) buss implementations.
The input connection is pre-wired to take its power from the +DTR or +RTS connection and to provide feedback to the other input connections to indicate that the device is on-line.
|Simple internal installation or inline cabling. Purchase the units with the optional PC bracket to mount inside the PC. Disconnect the DB 9-pin flying lead comm port connector, (or purchase the IDC flat ribbon cable extension for external to internal connections) route and attach it to the converter ...installation completed.||
Optional IDC cable assembly for connecting the external comport to the internally mounted converter. The flat ribbon cable easily slips in between the PC slot and PC bracket to gain access to the internal machine.
