Note:
These cables are with -48 V DC power supply, so make sure to prevent short circuits,
otherwise, the signal will be interrupted and the equipment may not work normally, and
even the equipment protection action will be activated. GND and -48 V each occupy
one twisted pair. These twisted pairs should be separate, otherwise short circuit may
occur.
