User manual JAMO MANNO6, IW1060SW

[. . . ] More IR receivers may be wired in parallel, in the same manner as shown, up to a maximum of twelve. More than twelve is not recommended because IR noise picked up by the many IR receivers may cause erratic operation and reduce remote control range. These may be added virtually without limit, provided power supply requirements are taken into consideration. Be sure to connect the +12V, Output and Gnd of each IR receiver and keypad to the respective +12VDC, IR IN and GND of the connecting block as shown. [. . . ] Having sufficient power supply voltage and current available is critical for proper operation. Be sure to take the following factors into consideration: a) The maximum current for proper operation from a 781RG Power Supply is 120 mA (milliamps). c) Most IR receivers draw 2 mA without signal and 10 mA with signal (check specs. d) Each 730 Smart Pad draws 7 mA without signal and 65 mA with signal. f) Each emitter draws 3 mA in low power mode and 12 mA in high power mode. g) Add 10 mA for each 794 or 797 Interface module used, if they are powered from the 791-44. h) When using combinations of these devices, add up the currents as shown in the following example. Do not exceed their maximum current capabilities as noted above!

Note: Since only one IR source can operate at a time, the lower current IR receivers (and 730 keypads if used) do not need to have their "with signal" currents included. The high power mode may be used in installations where you mount the emitters on an adjacent cabinet wall or door a short distance from the unit's sensor. Another instance is when you place an emitter inside the device, but cannot place it close to the IR sensor. In such cases, you may need the extra power of the high power mode to blast through printed circuit boards or around chassis structures. In addition, when using the lower output 283 and 286 Blink IR's, you may need the high power mode for some devices that have less sensitive IR sensors. The resistors also provide current sharing to each emitter and allow the use of dual emitters in combination with single emitters. You may, therefore, connect any combination of the 282, 283, 284, & 286 series of emitters in the same system, such as that illustrated in Fig. When using less than 10 of the emitter ports, you may plug into any of them without regard to order. Emitter Expansion If more than 10 emitter ports are needed, you may daisy chain from the HIGH IR OUT port on the 791-44 to the IN/OUT port on a model 790 passive connecting block as follows: You may daisy chain up to a maximum of 9 model 790's for 100 emitter ports total as shown in Fig. CAUTION: Never plug emitters directly into the HIGH IR OUT or HIGH IN/OUTports. 6 illustrates a single zone system where the Status indicator on a Xantech 780-80 IR Receiver and on a Smart Pad2 or 3 in a remote room, shows the ON/OFF status of an A/V receiver. The STATUS and GND terminals on the 791-44 provide convenient tie points for the voltage that drives STATUS indicators on certain Xantech products (such as the 780-80 IR Receiver & Smart Pad2 or 3). [. . . ] The STATUS and GND terminals on the 791-44 provide convenient tie points for the voltage that drives STATUS indicators on certain Xantech products (such as the 780-80 IR Receiver & Smart Pad2 or 3). Plug a 12V adapter, such as the Xantech 786-00 Power Supply, into a switched AC Outlet on the back of the A/V receiver (or integrated amplifier, preamp, etc. ). Cut the attached plug off the 12V adapter and connect the two leads to the STATUS and GND terminals on the 791-44 ("+" to STATUS, "­" to GND). Connect the 4-conductor inter-room cable between the 791-44, the Smart Pad2 or 3 and the 780-80 as shown in Fig. 6. [. . . ]
