In the Multiple configuration one Desktop Director™ must be reconfigured to have its termination
resistors removed (see below). This unterminated Desktop Director™ must be within 33 feet (10
meters) of the power supply
Desktop Director™ Termination Resistor Settings
Desktop Directors™ are shipped with the internal termination resistors enabled.
When two Desktop Directors are used in a single port, the termination resistors on the
Director closer to the power supply will need to be disabled. To do so follow the
steps below:
1.
Disconnect the Desktop Director cable from the Desktop Director.
2.
Remove the handset from its resting place and turn over the Director so you
can see the bottom of the unit.
3.
Remove the round black cover. This can be pried off with a knife blade. Or a
miniature screwdriver may be pushed firmly under the lip and then lifted
out to pop the cap loose.
4.
You will see a black rectangular transformer labeled T1. To the right of T1
locate and remove the jumpers labeled JP1 & JP2.
These are small jumper blocks that can be lifted off with needle- nose pliers.
5.
You’ll want to save the jumper blocks. You can store each of them on one of
the jumper pins.
6.
Replace the access cover removed in step 3 by pushing firmly in place.
