WARNING: Removing the Switcher board
disconnects the RAM battery backup. Save all
effects, timelines, personality files, and
engineering setups to disk before extracting the
board.
STEP 1: Power down the 8150 Signal Chassis. Remove the integral
front cover/air filter to access the 8150 Switcher board. Use
the Accom supplied tool to extract the Switcher board from
the chassis and lay it on a clean, static free, grounded work
surface.
NOTE: Seating the Delaystiks requires moderate pressure.
Ensure that the Switcher board is sufficiently supported so
as not to flex.
STEP 2: Install the Delaystiks in the SIMM sockets indicated in Figure
3-6, on the following page. Orient the Delaystiks as all other
Delaystiks installed on the Switcher board.
Lift the ejector lever all the way up before trying to seat the
Delaystik. Otherwise, the lever prevents you from fully
seating the Delaystik.
STEP 3: Remove the blank plate or Input module at the 15/16 AUX
3/4 slot at the rear of the chassis and install the Aux 3, 4
Output module in its place.
STEP 4: Use the Accom supplied tool to reseat the Switcher board in
the 8150 Signal Chassis.
STEP 5: Power up the Signal Chassis. Assign a known video source
to Aux buses 3 and 4 and confirm that video is present at each
output. Confirm that 1V p-p analog composite sync is present
on the Aux Ref output of this option module.
