Diagram Of Switcher Card

The dual 32-channel switcher card has the upper 32 channel switcher accessing the out-

puts of the Video DA side of the DSPABS-12 cards and the lower switcher accessing the

screen splitter output from the DSPABS-12 card.

The switchers have 2 types of controls.

1. Local “step” push button controls

2. Remote RS-232 Control

Each switcher is independently controllable

(Note) The lower switcher “looks” at each output 2x before going to the next card when

using the step button.

RS-232 Connection

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 switchers.

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).

The DSPABS-12 card has (2) 1x4 video compensating Distribution Ampliers with both

gain and high frequency adjustments. Two of the outputs go to the rear panel for outside

uses, one goes to the top video switcher, and the other one goes to the screen splitter

input.

The DSPABS-12 is a 2 camera video screen splitter card that does not require any

genlock feeds for the cameras. By using digital technology CVS is able to capture and

synchronize one camera to another so that the pictures can be split. The size, type and

position of the split are variable as is the position of the second camera in relation to the

rst.

The position or what part of camera 2 shows in the window is adjustable both horizontally

and vertically.

Camera Requirements: The DSPABS-12 will work with any line locked or internally

locked color or B&W cameras for input 1 and 2. Either camera can be line locked or

internally locked, however the internally locked camera will give you a better picture. Both

cameras must conform with RS-170A sync timing standards. This means they must also

be interlaced with the proper pulse widths and sync frequencies. It has been found that

some of the less expensive cameras while claiming to conform with RS-170A, actually do

not. This can cause instability in either picture. If you are unsure of the RS-170A sync

standard, please contact Compu-Video Systems at 845-737-7009.

SETUP/ALIGNMENT

·Install the cameras to cover the areas to be viewed. Take care that the area of camera 2

that you want to see in the split is in the center of the picture.

·Locate yourself at the screen splitter. With the front panel switch, verify that each camera

shows individually on the screen.

·Decide on the type of split that you will use. Example: Vertical split, Horizontal split,

Window.

·Decide where the split will be, and in the case of the window, what size it will be.

·Set the front panel switch to the center split position.

·It is recommended that you center the controls and vary each one while observing the

picture. This will give you a feel for the way each control effects the picture.

·Begin by adjusting the start of the split with the Height Start Control. Position the start of

the split as desired.

·Next set the end of the vertical split to its desired location using the Height End Control.

·If you are setting the window/split so it goes to the far right side of the screen,

perform the following steps: On the Width end control, vary this control to the minimum

split and slowly increase it so that the split goes to the right. Once you go past the end of

the screen you can continue. You will see no increase in split size but you may see the

picture jump to the side at a point. This indicates that you have gone too far and need to

adjust the control back to just before the picture jumps.

·Adjust the Width Start to position the left side of the split

·Adjust the Width end control to end the Horiz split. You now have a window that should

be positioned in camera 1.

·Adjust the Vertical position to center camera 2 in the window. You can open the window

with the Width and Vertical End controls to make this step easier. Once camera 2 is

properly set, close the window down to the desired size.

·After the split has been set, touch up the Horizontal and Vertical position controls to get

the slave camera’s optimum picture angle.

NOTE:

Once you have set up the unit and there is a slight side to side jumping on camera 2,

slightly adjust the Camera 2 Horiz delay to stabilize it.

Card Removal

Installation And Removal Of A Board Set (BS) From

The DA-34 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 source.

2) Remove the 4 screws holding the front panel in place.

Removal of a Board Set:

A) Determine which board set is to be removed. Locate the BS and then unplug

the board by gently pulling the board towards the front of the chassis.

B) On the rear of the unit 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 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.

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 and put the front cover back on.

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 specied.

If any problems persist, call 845-737-7009 and ask for tech support.
