Under normal setup, outputs 1 and 2 are identical. If a special compensation circuit is used
for pre-emphisis, output 1 will differ from output 2. Output 2 and the switcher output will be
the same. If you select the 1x4 mode of operation all 4 outputs will display Input 1. If
pre-emphisis is selected both #1 outputs will be different from the #2, and switcher
outputs.

Installation And Removal Of A Board Set (BS) From
The DA-3212 Chassis.
Boards can be Hot Swapped if needed but it is recommended that power be disconnected
before changing any boards.
1) Remove power from the system by unplugging the power pack(s) from the 110VAC
source.
2)Remove the 2 screws holding the desired board in the chassis
Removal of a BS:
A) Determine which board set is to be removed. Locate the BS and remove the
2 screws holding the board in place (Fig.8). Then unplug the board by gently
pulling the board towards the front of the chassis.
B) On the rear of the unit ( Fig. 9) is a matching connector board that must be
removed if a complete boards set is being changed. As there are no
electronics on the rear board you do not need to change it for repair purposes.
Locate the corresponding rear connector set, mark the connectors. Using a
small Phillips head screwdriver, remove the top and bottom screw from the
connector panel. Carefully, holding on to a connector, pull the panel away
from the rear of the chassis. Put the main board and the connector board
together.

Installing a Board Set in an open slot:
A) Locate the slot that the front board will be installed in. Holding the board so
that the components face left, carefully slide the board into the slot. Seat the
board in the mating connector in the motherboard. If you meet any
resistance, remove the board and check for bent pins and a misaligned
mating connector in the back of the slot. After correcting the error, reinstall
the board. Then reinstall both screws that hold the board in place.
B) On the rear of the unit you need to install the connector eld. Carefully align
the top pin on the back of the connector eld with the top pin on the internal
connector on the rear of the chassis. There may be open slots on the
connector in the chassis. After the connector panel is installed, using a small
Philips head screwdriver, install the two mounting screws in the panel.
C) Once the boards have been removed/installed you can reconnect the video
cables.
D) Reconnect the AC power and check for an LED on the video switcher
indicator or a video presence indicator. If none is visible, check you power
connections. If a problem persists, gently unplug the main board of the BS
you just installed. If the power returns, check for a misalignment when the
board is installed. If there is a shift from top to bottom you can improperly
install the boards and short the power supply. Reset the board.
E) Attach a test monitor the recently installed BS and test for proper operation.
Check for video. If none is present, check the installation of the rear
connector eld for a misalignment. Reset the rear connector panel and test
again. Align the board as specied.
If any problems persist, call 845-737-7009 and ask for tech support.
