Before proceeding, ensure that you have three Accom SIMM type
Delaystiks, Accom P/N 9400-0706.
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
3-8, 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 seating the
Delaystik fully.
STEP 3: Use the Accom supplied tool to reseat the Switcher board in
the 8150 Signal Chassis.
STEP 4: Power up the Signal Chassis. In the Keyer menu for each
keyer, press the Advanced Chroma Key softkey and verify
that there are now four selections for the Key Type: Luma,
Single, Dual, and Chroma 444. In the Color Corrector menus,
the selections are YUV, RGB, and RGB 444. However, you
can only select RGB 444 when the active Color Corrector is
for one of the key fill signals (M/E Keyer 1, M/E Keyer 2, or
DSK).
