  • Identical Operation
  • Newly Manufactured
  • Footprint-Compatible

The A-281C Control Board is part of a legacy DX cabin control system sold in the mid-1990s. This is a newly manufactured, footprint-compatible replacement that operates identically. The display interface can either be the legacy, 4-conductor cable with a Molex connector on each end, or it can be the newer 6-conductor RJ-12 cable with straight-through wiring.

Shown with Pin Connectors. (Most units before year 1999)

Our A-281C board also replaces the A-285 board, legacy boards with mfg p/n 42403, and legacy boards with mfg p/n 701800007.
