Purpose-built RS-232 adapter cable
This 1.5ft Velocity cable connects a DB9 male port to a 3.5mm male jack for three-conductor RS-232 serial control. It carries only ground on pin 5, transmit on pin 3 and receive on pin 2. The design suits computers, projectors and control units that require this limited wiring scheme. Fully moulded connectors add strain relief for permanent installs.
Repurposes existing audio cabling
The adapter lets you run RS-232 control signals over a standard 3.5mm stereo cable instead of pulling new DB9 wiring. It bridges the control unit and display using the three conductors already present in the audio lead. No extra software or drivers are involved; the cable simply maps the required pins. This saves installation time in retrofit AV projects.
Verify three-wire RS-232 requirement
Confirm that both the controller and the target device use a three-conductor RS-232 interface with common ground, transmit and receive only. Hardware needing hardware flow control, additional status lines or full nine-pin wiring will not operate correctly with this adapter. Check the pin-out documentation for each piece of equipment before ordering. The 1.5ft length also limits placement distance between units.

Questions about this item
Will the DB9 or 3.5mm connector need replacing after repeated mating cycles?
The fully moulded DB9 and 3.5mm connectors give strong strain relief, reducing wear from repeated insertion and removal.
What limits the maximum cable run when using this adapter for RS-232 control?
The adapter is only 1.5ft long and designed for 3-wire RS-232 with common ground, so total run length depends on the attached RS-232 cable.
Does the adapter generate any heat or noise when the control link runs continuously?
As a passive moulded adapter with no active electronics, it produces no heat and no audible noise during continuous RS-232 operation.
