Frequently Asked Questions - ML95K Xantech

Why is the talkback LED dim or not lighting during IR reception?

This can be caused by weak batteries in the remote control, a bad or unplugged emitter, an open signal wire between the receiver and connecting block, or an inadequate power supply. Verify the supply reads between 11.5 and 13VDC under load. Also check that the emitter is properly connected and functioning.

Why does the talkback LED flicker or stay dimly lit?

Common causes include reversed signal and ground wires, a defective emitter, high ambient noise from sunlight or fluorescent lighting, or EMI from dimmer switches or electronic devices. Use a SUN filter or a Plasma/CFL-friendly receiver like the ML95K. Reposition the receiver away from noise sources or add a 470Ω resistor across signal and ground.

Why is the talkback LED solid on?

This often indicates plasma display interference, reversed voltage and ground wires, or high ambient noise. If using near a plasma display, ensure the receiver is not reflecting interference. Also verify correct wiring and power supply voltage. If the issue persists, try a Plasma-friendly receiver.

The emitters are not blinking even though the talkback LED blinks. What should I do?

Check for a short in the emitter wiring (e.g., a staple through the cable) or an internally shorted emitter. Replace the emitter or use a test emitter to verify the circuit. For XTRALINK systems, ensure a DC blocker is used on TV legs without an IR receiver.

I have intermittent IR control; I need to press buttons multiple times.

Intermittent control is often due to plasma interference, high ambient noise, or long wire runs (over 100 feet). Use a Plasma-friendly receiver or add a SUN filter. For long runs, place a 470Ω resistor across signal and ground to discharge cable capacitance, and consider an amplified connecting block like the 791-44.

Some or all components do not respond to IR commands.

First, ensure the emitters are correctly placed over the component's IR sensor window. If the signal is too strong, reposition the emitter further away or use a lower-output emitter (283D or 286D). For equipment in a closet, use an emitter shield. If using a CB12 block, switch to a 789-44 which limits current.

There is absolutely no functionality. How can I identify the faulty component?

Start by verifying the power supply: measure voltage at the connecting block under load (should be 11.5-13VDC). Then test the emitters: disconnect all emitters and power, jump IR to +12V, reconnect power and one emitter; it should light solid. Finally, test the receiver: jump IR to GND, reconnect power, and point a remote at the receiver; the talkback LED should light.

Can I extend the 7-foot cable on the ML95K?

Yes. Cut off the mini plug, strip the leads, and splice to a 3-conductor extension cable. Use appropriate gauge: 24 gauge up to 200 feet, 22 gauge up to 600 feet, 20 gauge up to 2000 feet, 18 gauge up to 5000 feet. Connect the extension to the terminal block on the connecting block.

Can I use the ML95K outdoors or in direct sunlight?

The ML95K is Plasma/CFL-friendly and can be used in direct sunlight with a SUN filter (SUNKIT). However, the receiver is not weatherproof. For outdoor use, protect it from moisture and extreme temperatures.

What is the warranty coverage for the ML95K?

Xantech offers a Limited Lifetime warranty from the date of purchase by the original consumer. It covers defects in materials or workmanship. Xantech will repair or replace defective products at no charge, but does not cover installation or removal costs, nor incidental or consequential damages.

INSTALLATION

QUICK-START

A typical system will use an IR receiver, several emitters, and a power supply all connected to a connecting block.

1. Connect the IR receiver to the "IR RCVR" port on the connecting block. The 'red' connector is installed to the 'red' plug. Note: In some extended distances, additional 3-conductor may be required and can be connected to the terminals on the connecting block.

2. Connect the Emitters to the connecting block. The 'yellow' connector is installed to the 'yellow' plug.

3. Connect the power supply to the connecting block.

4. Installation complete

MOUNTING

Drill a 1/2" hole in any surface, such as a cabinet panel. Pass the lead and the body of the ML95 through the hole and secure from the rear with the nut (supplied).

In this system a 283D Blink-IR Designer Emitter is shown connected to the "OUT" jack. If expansion beyond two emitters is required, use the included Xantech 789-44 Connecting Block.

CABLE CONNECTIONS

ML95s may also be used where the 7-foot cable is not long enough. Simply cut off the mini plug, strip the leads and splice them to a 3-conductor extension cable with a terminal block or other means. Then connect the extension cable to the 3- or 4-terminal block on the connecting block.

3.5mm mini plug Signal Name
TIP SIGNAL
RING GROUND
SLEEVE +12VDC

The 3-conductor inter-room cable (24 gauge up to 200', 22 gauge up to 600', 20 gauge up to 2000', 18 gauge up to 5000'), is run to the main room.

While it is possible to make wired connections without the connecting block, it is not recommended. The connecting block reduces installation time, helps to eliminate errors, allows easy troubleshooting and permits easy system upgrades later, if needed.

PLACEMENT

The IR receiver should be located so that it is not directly facing a light source such as lamps or displays (standard, LCD, and Plasma). When mounted near a display, it should be flush to the display and away from light reflections that may occur.

LARGE SYSTEM APPLICATION

The ML95 IR receiver is compatible with all Xantech Connecting Blocks. Different connecting blocks are provided for application specific situations. For instance, in the diagram below, an optional 791-44 connecting block is used to control several components.

IR Troubleshooting Guide

NOTE: Due to the many variables in a given installation, the troubleshooting countermeasures you will have to take may vary from job to job. Each installation is different due to the number of IR receivers in use, length of wire runs, type of wire, amount of ambient IR noise present, etc.... Therefore, your countermeasures for a particular job will range from nothing at all, to any combination of the solutions listed below.

IR Receivers: Model #'s DL, HL, ML, and WL series

Symptom #1: DIM or NO Talk Back LED during IR Reception or reduced operational range

	Cause: Solution
1.	Weak Batteries in Transmitting Remote.	Replace batteries.
2.	Bad Emitter or no emitter plugged into connecting block.	Test emitter and verify wiring.
3.	Signal wire between IR Receiver and the Connecting Block is open.	Recheck wiring.
4.	Power Supply not putting out proper voltage.	Verify supply is a 12VDC regulated supply reading between 11.5 to 13VDC under load.Should be using Power Supply Model 781ERGPS (12VDC Regulated, 200mA) or 782ERGPS (12VDC Regulated, 1.2A)
5.	Output from the IR receiver/connecting block is connected to a high impedance IR input jack on a component.	If you are using a passive connecting block, such as a 789-44, and the system is not working, try the amplified connecting block, model 791-44. Put one of the small plastic case jumpers supplied with the block on the pins next to the emitter jack. This will provide the IR-in jack on the component with a hotter signal.
6.	IR Receiver is inoperable.	Replace Receiver.
7.	(XTRALINK Only) RF Amplifier is being used on same COAX Line anywhere between the Coupler (CPL94) and Injector (INJ94).	Need to use a Bypass Kit (model BYPASS94 Kit) to route the IR control signals around the amplifier(s).

Symptom #2: TB LED on IR Receiver (and/or Emitters) Dimly lit or flickering

	Cause: Solution
1.	Signal and ground wires are reversed or shorted either at the connecting block or IR receiver.	Recheck your wiring.
2.	Defective emitter.	Replace Emitter
3.	Relatively high levels of ambient noise. This can be due to any of the following: Sunlight, fluorescent Lighting or Plasma Displays.	In this case use either a SUN filter (SUNKIT), or any of our ‘Plasma/CFL Friendly’ IR Receivers (DL85/95, HL85/95, ML85/95, WL85/95). These can also be used in direct sunlight and in the presence of ‘tube style’ fluorescent lighting.
4.	EMI induced noise. This can be due to light dimmer controls or other radiating electronic devices (PC’s or any poorly shielded electronic device).	Reposition IR Receiver and/or cabling away from emitting device. You can also place a 470Ohm resistor in parallel with the IR Signal and GND connections on the connecting block. This will also help alleviate any stray capacitance in the cable.
5.	Plasma Interference	Use an 85 or 95 series Plasma ‘Friendly’ IR Receiver. If already using a 85 or 95 unit, please note the Plasma interference can be reflected off of any item it comes into contact with within approx. 3ft. From the front of the display. Keeping this in mind, make sure that the IR receiver is free from any obstruction that might reflect back into the receiving eye.

Symptom #3: TB LED on IR Receiver (and/or Emitters) on solid

	Cause: Solution
1.	Plasma Interference	Use a 85 or 95 series Plasma 'Friendly' Receiver. If already using a this unit, please note the Plasma interference can be reflected off of any item it comes into contact with within approx. 3ft. From the front of the display. Keeping this in mind, make sure that the IR receiver is free from any obstruction that might reflect back into the receiving eye.
2.	Voltage and Ground wires are reversed at the connecting block or IR Receiver	Recheck your wiring.
3.	Relatively high levels of ambient noise. This can be due to any of the following: Sunlight, fluorescent Lighting or Plasma Displays.	In this case use either a SUN filter (SUNKIT), or any of our 'Plasma/CFL Friendly' IR Receivers (DL85/95, HL85/95, ML85/95, WL85/95). These can also be used in direct sunlight and in the presence of 'tube style' fluorescent lighting.
4.	EMI induced noise. This can be due to light dimmer controls or other radiating electronic devices (PC's or any poorly shielded electronic device).	Reposition IR Receiver and/or cabling away from emitting device. You can also place a 470Ohm resistor in parallel with the IR Signal and GND connections on the connecting block. This will also help alleviate any stray capacitance in the cable.
5.	Power Supply not putting out proper voltage.	Verify supply is a 12VDC regulated supply reading between 11.5 to 13VDC under load.

Symptom #4: TB LED on IR Rec. blinks but 283D or 286D 'Blink' style Emitters do not

	Cause: Solution
1.	There may be a short, such as a staple driven through the Signal and GND wires of the IR Receiver and/or the emitter.	Recheck your wiring.
2.	Emitter may be shorted internally	Replace Emitter or use TEST EMITTER to check circuit.
3	(XTRALINK Only) TV on same splitter with no IR Receiver installed	Place a DC Blocker (Model 203-00) on any TV Leg without IR Receiver

Symptom #5: Intermittent IR control (i.e. buttons on remote need to be pressed multiple times)

	Cause: Solution
1.	Plasma Interference	Use a 85 or 95 series Plasma 'Friendly' Receiver
2.	Relatively high levels of ambient noise. This can be due to any of the following: Sunlight, fluorescent Lighting or Plasma Displays.	In this case use either a SUN filter (SUNKIT), or any of our 'Plasma/CFL Friendly' IR Receivers (DL85/95, HL85/95, ML85/95, WL85/95). These can also be used in direct sunlight and in the presence of 'tube style' fluorescent lighting.
3.	Long Wire Runs – shielded wire typically of 100 feet (30 meters) 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.

Symptom 6: Emitters function but some (or all) components do not respond.

	Cause: Solution
1.	Emitter placement is incorrect.	Reposition the Emitter so that it is directly over the components sensor window.Consult the components owners' manual of the unit for the exact location of the IR Sensor Window.
2.	Emitter placement is correct but the signal is overpowering the unit or there is bleed-through from other emitters close by.	Reposition the Emitter to a position that is suitable for the unit. Use a 283 or 286D 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.

Symptom #7: Absolutely No Functionality (How to determine which component is at fault)

Component to Test Instructions
1.	Verify Power Supply	With a Multimeter, measure the DC Voltage of the supply while it is connected to the Connecting Block. Put the Negative lead of the meter on the terminal marked GND and the Positive Lead on the terminal marked 12VDC (or V). You should get a reading between 11.5VDC and 13.0VDC. If not, remove the supply from the Connecting block and measure again this time directly on the 2.5mm Coaxial plug. If it reads between 11.5VDC and 13VDC, power supply is most likely good. Reconnect to the Connecting Block and proceed to step 2. NOTE: In most cases this will indicate the supply is good but in some cases the supply can still be bad (i.e. reads good when not plugged in but may not be able to handle the current load of the system.)
2.	Verify Emitter. (283D or 286D Blink Style ONLY)	Remove the power supply from the connecting block and all Emitters from the output. Place a jumper wire on the connecting block between IR and +12v. Reconnect the Power Supply and one emitter. The Emitter should Light bright and solid. Repeat for all emitters.
3.	Verify Emitter. (282M or 284M NON Blink Style)	Use a diode tester to verify proper Emitter operation. Remove Emitter from Connecting Block. Place the Positive Lead of the tester on the TIP of the Mono Mini Plug and the Negative Lead on the Shield of the Mono Mini Plug. Meter should read a voltage. When the leads are reversed (Positive lead on Shield and Negative lead on TIP) you should not get any voltage reading at all.
4.	Verify IR Receiver.	Remove the power supply from the connecting block and all Emitters from the output. Place a jumper wire on the connecting block between IR Signal and GND. Reconnect the Power Supply. With a known good hand-held remote, shoot a constant IR Command at the receiver and verify the TB LED on the Receiver lights.
