Aurora offers 4 different cables to interface our TRS jacks to 9-pin serial devices/ports.
The cables are 3 feet long.
F2T3R / F3T2R
M2T3R / M3T2R
F / M = Female or Male 9-pin on the CA0052 Series cable.
2/3T = Pin 2 or 3 is Transmit (Tip-to-9pin).
2/3R = Pin 2 or 3 is Receive (Ring-to-9pin).
Ground is Sleeve-to-pin5.
In the below example, the Epson projector has a Male 9-pin. The projector pinout is:
Pin 2 = Rx
Pin 3 = Tx
Pin 5 = Gnd
The cable required in this case would be: F2T3R
F = Female
2T = Pin 2 is our Tx to their Pin 2 Rx.
3R = Pin 3 is our Rx to their Pin 3 Tx.
