DMC-I Diagnostic Cable | DB9 To DB25 RS485

$300.00

Custom RS485 multi-drop cable for legacy DMC-I elevator controllers, built around the genuine Patton 2089 module specified in the original DMC service manuals for factory-correct protocol matching with DMC FAST. Interface-powered (no batteries or wall adapters) with custom circuit protection and a heavy-duty braided RJ45 cable, engineered so an accidental power-to-data crossover will not compromise the board.
