How to Customize a Receipt Printer Communication Cable

Friday, October 05, 2012 FingerTec 3 Comments

The original communication cable that comes with the EPSON Thermal Printer TM-T88IV is not compatible with the FingerTec terminals. A modification to the cable is required before you can use it with the FingerTec terminals.

Things to prepare:

1 X Male Serial Socket (9 pins).
1 X Male Parallel socket (25 pins).
1 X RS485 cable (1 meter).

Step 1: Solder the wires at RS485 cable to the serial socket as shown at the photo above.
Pin 2 – Orange, Pin 3 – Brown, Pin 5 - Red

Step 2: Solder the wires at the other end of the RS485 cable to the serial socket as shown at the photo above. Pin 2 – Brown, Pin 3 – Orange, Pin 7 – Red

Step 3: Place the soldered socket with the wires back to the casing.

Step 4: Screw and assemble the casing together.

Step 5: The printer cable is ready to be used.
