W312M SYS-Link MOD
The SysLink PFL detect circuits depends on a
good connection between the SysLink PCB’s
and the console chassis, the following
modification ensures that this can occur.
Add a wire link between the chassis connection
for P105 on the SysLink In card and a chassis
connection point in the console (the earth lug of
one of the ¼” jacks).
Add a wire link between the chassis connection
for P205 on the SysLink Out card and a chassis
connection point in the console (the earth lug of
one of the jacks).
Please note the following:
To make it easier to fit the Slave PCB to the
console, cut off the last three 40 way IDC
“bump” connectors from the main loom. The
fourth 40-way IDC “bump” connector plugs into
the Slave PCB and the Slave PCB then plugs
into the 4 x Mix Master PCB’s
When fitting or removing the console connector
panel with a SysLink Out PCB installed, always
loosen the “D” connector nuts. This enables the
SysLink Out PCB to drop down out of the way of
the metalwork when the connector panel is
removed or fitted. Make sure that once the
connector panel is fitted that you tighten the “D”
connector nuts again or the PCB may short out
on the chassis. Do not over-tighten the nuts or
they will break, firm but not tight is a good motto
here.
SysLink will only work if the Master Console is in
Mono Mode. SysLink only links to the Mono
busses on the receiving console. While it is
preferable for both consoles to be in Mono
Mode, if the Slave Console is switched to Stereo
Mode and the Master Console is switched to
Mono Mode then all will work.
THIS MOD DOSE NOT NEED TO BE FITTED
IF THE MIX MASTERS ARE ISSUE 4 OR
ABOVE.
Remove the Mix Master 3, 7, 11 PCB from the
Slave console (the second last master PCB)
Wire between Pin-38 of CN11 and the back of
P10
The PCB track of the Mix Master 3 board is to be
cut in two places. Cut between resistor R172
and Q16 (a very small gap), and also
cut between Pin-38 of CN11 and the base of of
Q16.
Add a 100K resistor in between R172 and Q16
Refit Mix Master 3 to the console.
