This enables it to be compatible, with both current and older display equipment. The Sync Polarity switch reverses the polarity of the incoming sync for compatibility with various displays The DA1203RM Distribution Amplifier is a state-ofthe- art product with a video bandwidth of 350 MHz, enabling it to remain transparent to the video signal passing through it. Each output is individually buffered and is not affected by other output loading. The DA1206RM offers an internal 90-140/200240V power supply and can be rack mounted using optional hardware accessories (DA1299RM – rack ears for single unit and DA1298RM – rack shelf for two units side-by-side).

DA1206RM Electrical DESCRIPTION OF DA1206RM 4 4 DISTRIBUTION AMPLIFIERS 4.1 SYNC POLARITY SWITCH The SYNC POLARITY switch is located on the back panel of the unit. It has two switching positions, one designated (+) and the other (-). By setting the sync polarity switch to (+) the signal is processed as unchanged and the sync polarity of the output signal is matched with the sync polarity of the unit. By setting the sync polarity to (-) the sync polarity of the output is changed to the opposite of the input. 4.2 SYNC LEVEL SWITCH The SYNC LEVEL switch is also located on the back panel of the unit and has two positions for switching — a sync level of 2V and a sync level of 4V. Most often a 4V-sync level is used. This should be considered as the default setting. The 2V setting allows compatibility with some older equipment that would be overdriven if a stronger signal were used. 4.3 VIDEO LEVEL SWITCH The VIDEO LEVEL Switch can be set to either the standard 0.7V output or to 1.0V output. When the switch is set in the 1.0V output position, this provides approximately a 35% increase in the video signal level. This can be used in installations where cable runs exceed 150 feet. It is not recommended that this switch be set in the 1.0V position for shorter cable lengths as the increased level may reduce the life of CRT displays if they are overdriven. 4.4 POWER The DA1206RM offers an internal 90-140/200240V power supply. A variety of different power supplies are available for international use. APPLICATION DIAGRAM 5 5 DISTRIBUTION AMPLIFIERS INSTALLING YOUR DISTRIBUTION AMPLIFIER 6 OPERATION 7 Step 1. Make sure that the proper power supply is being used with the unit. The use of an incorrect power supply can result in equipment damage not covered by warranty. Step 2. Connect the power cord to the unit and plug it into the power outlet. The power indicator LED on the front panel will light. This indicates that the unit is operational. Step 3. Connect the high resolution RGsB or RGBS source to the DA1206RM using coaxial cable with BNC connectors, making sure that the colors match correctly. Then connect one or two monitors or projectors to the output(s) of the DA1206RM. The monitors or projectors must be scan-rate compatible with the source signal - the DA1206RM does not affect scan rate. Step 5. If the image is less than perfect, check all of the connections. Also, check the settings of the switches. The default setting is Sync Polarity (+), Sync Level (4V), Video Level (0.7V). Check all of the connections. The unit is very reliable and seldom will be the cause of malfunction. Poor quality cables may often degrade the performance of the product. Make sure that the cables used are coaxial cables and that all pins are in good condition. CONGRATULATIONS! YOU ARE DONE. If you experience any problems, please call 1-800-258-4623 or 1-714-990-2300 for international calls. The settings of the DA1206RM Distribution Amplifier can be adjusted using Input Termination, Video Level, and Sync Level switches as described in Section no. 4. There are no other adjustments necessary to operate the unit. The DA1206RM will operate successfully as long a...
