Description
D-Sub 15-Pin ACC Interface Cable for Mobile Radios
Heavy-duty 15-pin D-sub accessory cable for PC management, external speakers, channel control, ignition sensing, and vehicle integration.
The Icom OPC1939 (also cataloged as OPC-1939) is an original equipment manufacturer (OEM) D-Sub 15-pin accessory (ACC) interface cable designed to expand the control and operational capabilities of Icom mobile two-way radios. Pluggable directly into the rear accessory port of compatible mobile transceivers, this cable exposes critical input/output (I/O) signal lines, allowing system integrators and fleet managers to connect external hardware without modifying internal circuitry.
By routing essential control lines—including receive audio output, modulation input, remote channel switching, ignition sense, and auxiliary output triggers—the Icom OPC1939 enables advanced custom installations. It allows mobile radios to connect directly to computer dispatch terminals, external high-output speakers, ignition switches for automatic power management, or vehicle horn systems for public address or emergency alerting. Housed in a durable shielded jacket with industrial-grade connector strain relief, the Icom OPC1939 ensures reliable signal integrity across commercial and public safety fleets operating under FCC Licensing regulations and DMR Association standards.
