11.12 HD-SERIES SUBRACKS AS COMBINERS
The HMX32128 subracks can be used as combiners, with 3 operating modes selectable
by DIP switch number 3, positions 7 & 8.
Normal operating mode is selected by SW3 / 7 and SW3 / 8 in the OFF position. Other
operating modes are shown below.
When creating a 32C08 combiner by using a 16C08(A) and a 16C08(B) both subracks
share the same ID.
11.13 INSTALLATION TIP
If operating the HD Series switcher with the front cover removed, the input and output
cards (HMX832, MX108, MX208, MX116) may have a tendency to move forward slightly
when coaxial connectors are being installed on the rear. Before testing your HD Series
switcher, ensure all cards are seated correctly. It is for this reason that it is a good idea
to leave the front panel on until you are ready to commission/test.
