How to Identify a 968 Series
Programmable Patchbay:
968 Series programmable patchbays can only be identified
by removing the top dust cover and looking for the
presence of red and white programming shunts inside.
How to Change the Programming for a Circuit:
1. Remove the top dust cover to expose the programming
shunts.
2. Find your desired configuration in the diagram above.
3. Arrange the programming shunts to match the
appropriate diagram. Note: Each circuit can be
programmed independently.
4. Ample shunts are provided with every programmable
patchbay. All shunts should be placed vertically. Red
shunts are used for grounding options. White shunts
(shown as light gray above) are used for normaling
options.
5. Replace the dust cover.
