The switcher board ( Fig. 2 / Fig. 3 ) has 2 controls, a Step Switch Button, and a Remote/
Manual select for switcher control. To setup the system up, select the Manual position on
the slide switch and connect you test monitor/ equipment to switcher out 1 or 2 and using
the step button, step through each input making the needed adjustments as you go. You
can leave both switcher outputs connected at all times or you can use just the one you
need.

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.

MULTI-SWITCHER SETUP:
A CS-1600 can be used as a master switcher to be fed by the DA-3212 slave switchers,
or a DA-3212 can be set up as a master if desired. To connect multiple units together to
enlarge the number of inputs you must set the slave units up for the proper addresses.
A) Determine which unit will be the master. All units are preset as masters from the
factory. Put it aside.
B) On each of the slave units:
Disconnect the power to the unit.
Remove the switcher card
Using the master slave diagram Fig. 13, locate:
The Master/slave suitcase jumper
The 8 pos Dip switch
C) Determine the ID number to be used for each slave unit,
(i.e. unit 16, or 15 or 14....). Mark the unit as to the ID number it is set for. Written in
pencil on the bottom will do the trick!
D) Set the suitcase jumper to the Slave position as shown in the master slave jumper
setup diagram.
E) Set dip switch #5 to the off position.
There is an eight position dip switch located on the control board. It is factory set for
machine #1 and the suitcase jumper is set for a master unit. To add addition units you will
start at the highest number and count down as shown in the system diagram. The master
will always be machine 1 unless there are 16 slave units. The slaves will start at 16 and go
down to 1 as they are added.

The following is an example of a GW basic program used to control from 1 to 16 DA-3212s.
The factory preset is machine #1, whose command is on line 910. The rst group of
characters are used to determine which machine number is being activated in a multi
switcher system. Normally machine #1 is used a default. The second group determines the
Input that will be switched to the output once the commands are sent. Line #905 represents
the settings for the RS-232 Com. port. If you have any questions please call Compu-Video
Systems at (845) 737-7009 between the hours of 9am and 5pm (EST).

DA-3212 Multi Input Cable Comp. DA
The DA-3212 consists of a CH-3212 card frame system and (16) DABS-2032. Each card has (2) 1x2 adjustable cable compensating
ampliers with ground loop blocking, surge protected inputs. The DA-3212 includes a built in 32 pos. sequential, RS-232 controllable
switcher which can be operated locally, with an optional remote control unit or a computer. For 1x1 operation use only the output needed and
simply leave the unused one unterminated or each board can be congured for 1x4 operation. Output 1 of each channel can be custom “pre
emphasized” for driving long cable distances. On the front of the unit in addition to the video inputs, you will nd the switcher output, remote
switcher control input, local switcher controls, indicators and video presence indicators for each input. The individual I/O boards are
interchangeable through the front of the unit. The DA-3212 has 2 power supply inputs for optional power back up. Optional terminal strip
power input connectors for Din rail type power sources are available
