The DA-12, has diode protection on their inputs. When used in conjunction with an
outdoor camera or cable runs that run between buildings it is recommended that a
lightning protection device be added to the cable. If lightning strikes in the area and
causes a large enough voltage spike in the video feed cable, the input diode(s) will
sacrifice themselves causing the unit to fail. If the spike is large enough the input video
amplifier will be destroyed in addition to the diodes failing. These failures are not covered
under warranty. This unit is designed to act as a protector for the input stage of your recording device, but will only offer a limited amount of protection. Installation of a lightning
arrestor will greatly reduce any probability of failure of these units.
Use a seperate 12VDC @ 300 to 800ma power pack instead of an AC power source
for optimum operation.
There are now several cameras on the market that do not have power isolation
transformers in their power inputs. This can cause a serious problem with the DA-12
when a common AC transformer is used. If there is any doubt as to if you camera has this
problem, please DO NOT use the same power pack for the camera and the DA-12. For
any questions about the camera please contact your supplier. For any questions about
the DA-12, please contact us at 845-737-7009 between the hours of 9AM and 5PM EST.
SURGE PROTECTION
This device has each input equipped with a surge
protection device. In order to provide maximum
effectiveness, you must connect the ground screw
located on the rear by the power connector to an
electrical ground or a cold water pipe ground.
THIS IS NOT A LIGHTNING ARRESTOR. IT IS
ONLY RATED FOR +/- 15 KV AIR AND +/- 8 KV
CONTACT.
Due to changes in technology it is recommended that this unit be provided with no more
then 12-18V AC or 12-18V DC where 12-18V DC is preferred

The CCA-200 is a Differential input, high performance 1x2 Color Video cable compensating
Amplifier in a compact chassis. A differential input amplifier is used to minimize or
eliminate ground loop problems along with adjustments for Gain, HF compensation and
Cable compensation. The CCA-200 includes a 12VDC power pack but to save AC outlets
the CCA-200 also operates from 18-24VAC and can be powered off of the AC Camera’s
power transformer. Designed for +1000 foot to +5000 foot coax cable runs. For less than
1000” use the LDA-100. For 1x1 operation use only the output needed and simply leave the
unused one unterminated.
Please take the time to completely read this manual before attempting to install and align
the CCA-200.

Installation:
Mount CCA-200: Before the unit is to be mounted you will need determine where to mount
it, allowing for clearance for the BNC connectors and the cables. Do not mount the unit
over a heat source! Using the four #8 screws, secure the unit to the mounting surface.
The CCA-200 can be mounted in an equipment rack if there are rear rails. The cover
mounting holes will match up on one side with the EIA rack rails. Use whichever screws the
rack setup needs to mount the CCA-200.
After the CCA-200 has been mounted, connect the power.

On the CVT-1230 power pack, the wire with the white trace is the Positive (+) and the
unmarked wire is the Negative(-) lead. If you reverse these, the unit will not operate.
Simply reverse the leads to make the unit function.
Using Figure 2, connect the CVT-1230 to the CCA-200. Once power connections are
made, pin 1 and 4 should be open. Pin 1 will be used if a ground is tied to the unit.
If you are to use a 24VAC camera power pack use Figure 3 for the connections. Once
connected pin 1 and 3 should remain open unless a ground is tied to pin 1.
Make sure that the wires are secure in the power connector. It is recommended that an
earth ground is connected to the unit. This cannot be the same as the (-) on the 1218VDC or one side of the AC power.

CCA-200 SIGNAL LEVEL ADJUSTMENT:
Without An Oscilliscope:
1) Turn all front panel controls to their minimum (-) Counter Clock Wise (CCW) positions
2) Connect the signal from the Video source that is located over 1000’ away. Connect a
monitor to one of the video outputs and make sure it is terminated in 75 ohms.
3) Pick an white object in the picture and while adjusting the “Line” pot, look for black or
white smearing on the edge of the object (See Figure 4). You want to minimize or
eliminate this smearing. Once this is done, adjust the “Gain” Clock wise (CW) to the
approx. center position. Check for smearing on the white object. Touchh up the “Line”
adjustment to optimize the smearing.

4) Adjust the “Gain” control for a normal picture level with out adjusting the monitor’s
brightness or contrast leaving it a little on the bright side.
5) Looking at the fine detail in the picture, adjust the “Hi Freq” control CW to get the
sharpest picture possible without it getting noisey. If no change is noted, leave at max
CW.

With an oscilloscope connected to the output and the output cable terminated in 75 ohms,
1) Adjust the “Line” control CW to square off the sync.
2) Adjust the “Gain” control CW so that the sync signal is 400mv or if a 1VPP test signal is
available, adjust the “Gain” control for an overall level of 1VPP at the end of the cable.
3) Adjust the Hi-Freq. control CW until the sync edges just begin to peak.
Service: There are no servicble parts inside the unit. Please return to the manufacturer for
proper repair of this unit. Instructions are included in the Warrenty section.
