Vi2/4/6 Master Bay jumper change for V4.9.0 software update
From the previous software update V4.8.2.234 onwards for Vi2, 4 and 6 consoles, a
hardware change has to be made on the host console in order to function correctly.
When installing V4.9.0, if the console was previously updated to 4.8.2.234 then this
modification should have already have been done. If the console still has an earlier version
software than 4.8.2.234 then this change will need to be done.
The hardware change is simple to perform and comprises a change of one push-fit jumper
position on the Master Vistonics Control board.
Which consoles need to be modified?
Note: This modification is not applicable to Vi1 consoles. Vix000 consoles use a different
software version and the modification is not relevant to these consoles.
st
From 1
October 2014, the modification was done on all new Vi2/4/6 consoles in the factory,
therefore all Vi2, 4 & 6 Control Surfaces shipped before this date will need to be modified.
The serial number cut-off information is as follows, note that several different serial number
formats have been used since 2006:
Early consoles with serial number format starting 000xxx or 100xxx (shipped 2006-
2008)
All Vi4 and 6 consoles need to be modified.
Vi2/4/6 consoles serial number format starting 301: (shipped 2008-2014)
All Vi2, 4 and Vi6 consoles need to be modified.
Vi4/6 consoles serial number format starting 201: (shipped 2014)
Vi4 consoles: Before serial number 20150548 need to be modified.
Vi6 consoles: Before serial number 20160545 need to be modified.
Vi2 consoles: All consoles shipped before 30/09/2014,
If your Control Surface has a serial number which doesn't appear to match any of the above
formats, it will need to be modified.
How to identify if a console has NOT been modified
If you install the 4.9.0.xxx update but do not change the jumper setting, the console may
appear to work normally initially, however undesirable behaviour will come to light at some
stage. The problem will be that the faders in the Master (Control) Bay will experience erratic
operation, with some faders jumping up or down, either when a show is loaded or when
Gang mode is used.
A simple test to prove whether the modification is done is as follows:
(V4.8.2.234 or V4.9.0.xxx must be already be installed for this test to make sense).
Engage Gang mode and make a Gang with all 8 faders in the VCA/Bus master section (the
selected fader layer is immaterial). Start with all faders at minimum, then move any of the
faders except fader 1 up. If fader 1 then jumps to the top of travel, this indicates that the
modification is not done.
