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.
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.
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.
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.
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.
