Master / Monitor Board Jumper Settings
The right-most and and left-most of the Master boards in the console
must have jumpers set to ensure the comms is terminated correctly (or
the Monitor board if this is right-most or left-most).
The diagram below shows where the two sets of jumpers are on the
Master card (just above the
OUT
and
IN
serial connectors) and the
numerical labelling on the pins themselves.
J31 and J33 are the jumpers to be set, and the following applies
regardless of how many Master and Slave cards there are in the console,
or whatever configuration they are in.
•
The most left hand Master (or Monitor) card in the console should have
both sets of jumpers over pins 1&2.
•
The most right hand Master (or Monitor) card in the console should have
both sets of jumpers over pins 1&2.
All other Master cards (or Monitor) should have their jumpers placed over
pins 2&3.
If the Monitor card is at either far left or far right on the console (rather
than a Master card), then it is the Monitor board that needs to have the
jumpers set on pins 1&2, instead of a Master card.
Slave cards do not have these jumpers fitted.
NB:
On a 8-channel console that does not have a
Monitor
AD/DA card, the
single
Master
card should have its jumpers on pins 1 & 2.

Failure to set these
jumpers will result in
the system not locking
to the selected sync
source correctly.
