Cable
Building your own cable:
Note: Requires soldering and assembly. It is expected that the technician has experience in electronics, soldering and assembling cables and connectors.
Use a cable that contains at least the wires required (not single wires). Heat Shrink Tubes must be applied to soldered wire/pins. Test connection (beep) with
Voltage Meter. Test connection between power pin and other pins to ensure no short circuit is present prior to connecting cable and power on Display unit.
Finally, the 9-pin DSUB must be covered by a back shell.
