1. or longer causes a filter effect due to accumulated capacitance of the wire Intermittent or no IR control could actually be because of the longer wire runs Putting a 470 ohm resistor in parallel at the connecting block between signal and ground will effectively discharge the capacitance of the wire This will allow the signal to travel farther on shielded wire Adding a resistor between the input and ground of the connecting block will drop the IR level down somewhat Passive connecting blocks such as the 789 44 may not have enough signal output for consistent control of the equipment You may have to upgrade to an amplified connecting block to bring the IR level back to normal In these cases the 791 44 would be an ideal connecting block for single zone systems while the 795 20 would work best for a 2 4 zone system 08905105A Symptom 6 Emitters function but some or all components do not respond Cause Solution 1 Emitter placement is incorrect Emitter placement is correct but the signal is overpowering the unit or there is bleed through from other emitters close by Using a CFL Friendly IR Receiver 291 80 480 80 or 780 80 and trying to control a unit with a carrier frequency greater then 40kHz l e RCA DSS Scientific Atlanta Jerald and General Instruments Cable or DSS Set Top Boxes 08905105A Reposition the Emitter so that it is directly over the components2. sensor window Consult the components owners manual of the unit for the exact location of the IR Sensor Window Reposition the Emitter to a position that is suitable for the unit Use a 283 or 286M Blink style emitter they have a lower output than non blink emitters 282 and 284M If the components do not need to be controlled directly without an IR Repeater system components are located in an equipment closet place a Mouse Emitter Shield cover over the Emitter PN MS1 The rounded non stick side of the emitter is a hi output side and can reflect off other devices and overpower some components IR Sensors If using a CB12 connecting block try a 789 44 connecting block This has a series resistor at the output which will limit current to the Emitter If you are using the 291 80 or 780 80 CFL Friendly receiver locate the Carrier Frequency Adjustment on the unit and using a small blade screwdriver 3 32 blade width max rotate the adjustment for best performance of all the units in the system Note The 480 80 version does not have this feature you will either need to change the unit to a 291 80 780 80 or the 490 90 The 490 90 is a wide band unit and will not require any frequency adjustment Symptom 7 Absolutely No Functionality How to determine which componentis at fault Component to Test Instructions With a Multimeter measure the DC Voltage of the supply while it is connected to the Connecting Block Pu

ION This unit is meant to be interfaced to Xantech Connecting Blocks such as CB12 789 44 791 44 etc MOUNTING 1 Drill a 3 4 hole in any flat surface such as a cabinet panel Pass the cable and body of the 490 85 through the hole and secure from the rear with the nut Supplied 08905105A 1 IR CARRIER ADJUSTMENT The 490 85 is factory set to an IR carrier repeat frequency of 39kHz This will be correct for the majority of installations However some manufacturer s components that you wish to control may use different carrier frequencies such as RCA DSS satellite receivers that use 56kHz If sure carrier frequencies fall within the range of 32kHz to 56kHz you can adjust the 490 85 to match them for the best range performance The adjustment can be made through the small opening on the rear To adjust proceed as follows 1 First try the 490 85 in a repeater system If it works well with good range do not make any adjustments 2 If it does not work or has poor range less than 15 feet determine the IR carrier frequency of the product you wish to control Contact the manufacturer of the product if necessary to determine this frequency 3 Using a small blade type screwdriver rotate the adjustment shaft until the slot lines up with the desired frequency 4 If you have products in the same IR system that have different IR carrier frequencies you will have to adjust the 490 85 to a midway position For example some may ope
