RS-232 to RS-422/485 Converter

This Black Box ICD100A converter optically isolates and translates unbalanced RS-232 signals into balanced RS-422 or RS-485 formats. It supports half- or full-duplex RS-232 input and provides full-duplex RS-422 or 2-wire half-duplex and 4-wire full-duplex RS-485 output. The unit extends serial communication up to 4000 ft.

DIN Rail Mounting and Ports

The external form factor is designed for DIN rail installation inside industrial cabinets. It presents three ports for the serial connections. Opto-isolation protects connected equipment from ground loops and voltage spikes. No software drivers are required for the hardware conversion.

Check Power and Signal Needs

Verify that your existing RS-232 device operates within the electrical specifications of the converter. Confirm whether your RS-422 or RS-485 network requires full-duplex or half-duplex wiring. Ensure a suitable power source is available for the external unit.

Questions about this item

How can I confirm the RS-232 to RS-422/485 converter is operating correctly after DIN rail installation?

Verify the link by checking that data passes between the RS-232 port and the RS-422 or RS-485 ports over the full 4000 ft distance without errors.

What comes in the box with the ICD100A and what must I source separately?

The unit itself is included; you will need to supply RS-232 and RS-422 or RS-485 cabling, a suitable power source and DIN rail mounting hardware.

Which version of the converter should I choose for a 4000 ft RS-485 run?

The ICD100A supports 2-wire half-duplex and 4-wire full-duplex RS-485 up to 4000 ft, so select this model for that distance.
