NILES AUDIO CORPORA TION – 1-800-BUY -HIFI – 305-238-4373 1 INTRODUCTION The MSU-250 an infrared (IR) extender system enables you to control your IR remote controlled A/V equipment from a remote location.
2 FEA TURES AND BENEFITS The MSU250 offers a number of improvements over other IR Extender Main System Units: • Universal system—compatible with virtually all brands of A/V equipment and remote controls • Accommodates two IR sensors or keypads • Provides five flasher outputs via convenient 3.
12VDC power supply (supplied with the MSU250 Main System Unit) plugged into an unswitched AC outlet powers the system Power , IR da ta, status signal and ground via CA T -5 wire 12VDC power supply (No.
1. 12VDC Jack – Provides 12 volt DC power to MSU via a regulated power supply 2. IR Flasher Outputs – 3.5mm jacks provide output for either single or dual (MF1, MF1VF , MF2, MF2VF) low-level flashers 3.
5. Status/IR Confir mation LED – This LED performs two functions: (1) it provides a visible indication of system status via a green LED and (2) confirms the reception of IR data via a blinking blue LED 6.
INST ALLA TION CONSIDERA TIONS (CONTINUED) WIRING From every IR Sensor location you must “home-run” a CA T -5 cable back to the MSU250. Home run means that an individual cable is connected between each IR Sensor and the MSU250 (Figure 4).
Figure 5 An IR sensor cable is “daisy-chained” from an IntelliPad, to a sensor and back to the MSU250 INST ALLA TION CONSIDERA TIONS (CONTINUED) INTELLIP AD WIRING When you are placing both a IntelliPad and a sensor (or two keypads) in one room you may “daisy- chain” using a single cable.
T INST ALLA TION TOOLS REQUIRED • 1/8” (0.3cm) Standard Slotted Screwdriver • Wire Stripper INST ALLA TION Before you begin, make sure that the sensor/keypad cables, the flasher cables and the 12VDC power supply cable will all reach the proposed location of the MSU250.
T INST ALLA TION (CONTINUED) 1. Connect and test the power supply . If it tests OK, unplug the connector from the power socket and proceed A) Plug the supplied 12VDC power supply into an unswitched 12.
INST ALLA TION (CONTINUED) 3. T est for shorts and interference . A) Reconnect the power supply . If the power LED lights and the IR test LED stays off, unplug the connector from the power socket and proceed to Step 4.

TROUBLESHOOTING TROUBLESHOOTING GUIDELINES There are three basic problems which prevent proper operation. In the order of probability the problems are: 1. Bad Connections or Wiring If the connections or wiring are wrong, loose, shorted or open the system will not operate properly .
TROUBLESHOOTING (CONTINUED) 1. Move the sensor or the sensor cable away from the EMI source or move the source of the EMI away from the sensor or the cable 2. Connect the sensor ’ s GND terminal to true earth ground (if this isn’t feasible use the main system unit’ s GND terminal) 3.
