User manual NILES AB-8

[. . . ] The AB-8 is compatible with all Niles infrared repeaters, infrared routers, and multi-zone keypad systems. Tools Required ·1/8" Standard Slotted Screwdriver FEATURES & BENEFITS · Two infrared L. E. D. 's give the AB-8 exceptional range and power. With proper placement, a single AB-8 flasher can control an entire stack of audio /video components. · An adhesive-backed Velcro strip is included with the AB-8, providing quick, secure, "remove and replace" mounting. [. . . ] · An adhesive-backed Velcro strip is included with the AB-8, providing quick, secure, "remove and replace" mounting. · The AB-8 is supplied with an ample ten feet of connecting wire. INSTALLATION CONSIDERATIONS The AB-8 is typically used as a "flooding" flasher to control a stack of audio/video components. For this type of application, place the AB-8 with its L. E. D. 's pointed straight up and at least an inch in front of the equipment you wish to control (See Figure 1). The effective range varies between 8" and 30" depending on the brand and/or the model of the audio/video component. Note: If cabinet dimensions permit, experimenting with the placement of the AB-8 may yield better operating results. For example, place one AB-8 at the top of a stack with the L. E. D. 's pointing down and one AB-8 at the base of the stack with the L. E. D. 's pointing up (See Figure 2). In some installations there are shelves blocking a direct path between the AB-8 and the components' IR sensor window. It is possible to bounce infrared light off of smooth reflective surfaces (particularly white surfaces). If a suitable surface exists (like the back of a cabinet door, or a white wall within a few feet) try to place the AB-8 so that its reflected output reaches the sensor windows of the audio/video components (See Figure 3). If some of the components are still not getting adequate signal, mount a Niles IRC-2 MicroFlasherTMon the sensor window of each of the problematic components. Replace the AB-8 with an IRC-2 for each component controlled by the problemcausing flasher. The IRC-2 comes with a plastic IR blocking cover which will prevent the IR output of the flasher from reaching the sensor in the same room. SPECIFICATIONS IR System Compatible with virtually all brands of remotes using carrier frequencies between 26 and 60 kHz IR Transmitting Range 18 to 30 feet if mounted so that the transmitting L. E. D. 's face the sensors in a direct line of sight. IR Transmitting Angle Variable with the brand and/or model of the audio/video component. Because of the high power and "flooding" pattern of the AB-8, extreme transmitting angles can be successfully used if the sensor window of the component is close. Unit Dimensions 1" Wide x 2" High x 3/4" Deep (Includes Velcro) Mounting Supplied with self-adhesive tape attached to Velcro strips Wiring Requirements Supplied with 10 feet of 2-conductor 22 gauge connecting wire. Substitute an 18 gauge 2-conductor wire for distances ranging from 10 to 20 feet and a 16 gauge 2-conductor wire for up to 200 feet. Testing the Remote Control Test that the hand-held remote control operates the component when you point it at the front panel (check the batteries if it does not). Main System Unit Power Supply Check that the red power light on the Main System Unit is lit (the wall adapter should be plugged into an active AC wall outlet and the wall adapter has to be supplying 12V DC). Adjusting the Flasher Level Try adjusting the flasher level up or down (some components sensors are overloaded by too strong a command from the AB-8). If the operation of the component improves when the flasher level is all the way down, but it is still not perfect, try moving the AB-8 so that Optical IR Feedback Loop If there is an IR sensor and an IR flasher located within the same room--an "optical IR feedback loop" can occur. This occurs when the IR output from a flasher unintentionally reaches an IR sensor located within the same room.

This occurs when the IR output from a flasher unintentionally reaches an IR sensor located within the same room. The IR commands are eventually forwarded back to the IR flasher and the whole process endlessly repeats itself. This effect is similar to acoustical feedback (the howling or whistling sound heard in a P. A. [. . . ]
