RS-232 to RS-422/485 converter for long runs

This Black Box ICD100A converter bridges RS-232 equipment to RS-422 or RS-485 networks over distances up to 4000 ft. It provides three ports: two RS-232 terminal blocks and one DB-9 connection. The external power adapter keeps the unit running in industrial and commercial environments. TAA compliance makes it suitable for government procurement projects.

Din-rail mount with terminal blocks for quick wiring

The 1-inch high enclosure fits standard din rail and measures 3.1 by 4.2 inches, so it slides into crowded cabinets without tools. Terminal blocks accept stripped wires directly, removing the need for custom cables. Installers must match the RS-422/485 mode to the host protocol, otherwise data will not pass. The external power supply adds a second cable that must reach an outlet.

Questions about this item

How do I verify the ICD100A is converting signals correctly over the full 4000 ft distance?

Connect a known-good RS-232 device to the DB-9 port and an RS-422/485 device to the terminal blocks, then confirm error-free data exchange at the far end of the cable run.

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

The converter ships with the external power adapter; you supply the DB-9 cable for the RS-232 side and the wiring for the two RS-232 terminal-block ports.
