The interface connector on the Desktop Director™ is a standard modular RJ-45 style jack.

IMPORTANT!
Be very careful to label wiring used with RJ- style connectors. In some cases they have power
on them, and there is a risk of applying this power to something which does not expect it.
For this reason we suggest that you use different colored cables (or connector boots) on the
Desktop Director cables versus your Ethernet & ISDN Cables.

DEEP TECH NOTE!
If the above wiring table looks familiar to you, that’s not surprising, this looks just like the
ISDN S interface on any piece of ISDN terminal gear! That’s not a coincidence, our work
with ISDN led to using this robust interface for other purposes as you see here.
