Frequently Asked Questions - AVO-VGA Intelix

How do I connect multiple VGA sources to my display using the Intelix AVO-VGA?

Connect each VGA source to one of the four input ports on the switch, then connect the output port to your display using a VGA cable. Select the desired input using the front panel button or automatic detection.

Does the AVO-VGA require external power?

Yes, the switch needs 5V DC power. It can be powered via a USB port (included cable) or an optional AC adapter. Without power, the switch will not operate.

What is the maximum resolution supported?

The Intelix AVO-VGA supports resolutions up to 1920x1200 @60Hz, including 1080p. It is compatible with standard VGA signals.

Can I use the switch with a VGA to HDMI adapter?

Yes, you can use active VGA to HDMI converters. However, the switch itself only passes VGA signals, so any conversion must be done externally.

Why is there no picture on my display?

Check that all cables are securely connected, the switch is powered, and the correct input is selected. Also verify that your source device is outputting a VGA signal.

Does the switch support audio?

No, the AVO-VGA is a video-only switch. For audio, you must connect separate audio cables from your source to your display or speakers.

How do I clean the switch?

Disconnect power and use a soft, dry cloth to wipe the exterior. Do not use liquids or abrasive cleaners. Avoid cleaning the ports.

Can I mount the AVO-VGA on a wall?

The switch does not include mounting holes. It is designed for desktop use. You can place it on a flat surface or use adhesive pads.

Is the switch hot-swappable?

Yes, you can connect or disconnect VGA cables while the switch is powered on without damaging the device. However, always handle cables with care.

Where can I find replacement parts for my Intelix AVO-VGA?

Contact Intelix support or visit their website for replacement power adapters and cables. The switch itself is not user-repairable.

USER MANUAL AVO-VGA Intelix

The Intelix AVO-VGA balun set transmits VGA video passively over standard unshielded twisted pair cable, such as Cat 5, Cat 5e or Cat 6. The AVO-VGA eliminates costly and bulky VGA cable, and extends video transmission distances.

Pre-Installation

Note: The AVO-VGA does not support VGA handshaking and control signals. Therefore, it is necessary to set the monitor attributes prior to installing the balun set. First connect the source (typically a computer) directly to the destination (typically a monitor) with a standard VGA cable. After doing so, set the monitor attributes to the required settings (i.e., resolution, color, etc.). For best results, also set the contrast and brightness to the maximum level.

The AVO-VGA features shielded RJ45 connectors, which are provided as an option in harsh electrical environments, such as installations with large motors or cable runs near sources of interference. In such environments, shielded twisted pair cable (STP) may provide additional noise immunity. When using STP, ensure the shield on both ends of the cable run is terminated to a shielded RJ45 connector.

Caution: Do not attempt to disassemble or alter the balun housing. There are no user-serviceable parts inside the unit. Doing so will void your warranty.

Installation

1. Power off the source and destination devices which will be connected to the baluns.
2. Verify the modular outlets and cross connects to which you will connect the AVO-VGA are configured properly and labeled appropriately to identify the circuit.

Caution: To minimize the possibility of equipment damage from electrostatic discharge (ESD), all source and destination equipment must be powered off during installation. This includes signal extenders, splitters, and switches.

1. Verify the desired twisted pairs are not being used for other LAN or telephone equipment.

Caution: Do not connect the balun to a telecommunication outlet wired to unrelated equipment. Doing so may damage the unit or any connected equipment. Ensure all connected twisted pair cabling is straight-through (point-to-point).

1. Connect the send balun (AVO-VGA-S) to the VGA port of the source equipment. Tighten the mounting screws on each balun.
2. Connect one end of the twisted pair cable to the send balun. The RJ45 pinout in the twisted pair cabling should conform to the EIA/TIA 568A or 568B standard.
3. Connect the receive balun (AVO-VGA-R) to the destination equipment.
4. Connect the other end of the twisted pair cable to the receive balun. The RJ45 pinout in the twisted pair cabling should conform to the EIA/TIA 568A or 568B standard.

Note: For your convenience, it is recommended that you uniquely mark the ends of the twisted pair cable before pulling them through a wall or conduit.

1. Power on the source and destination equipment.
2. If necessary, set monitor contrast and brightness to the desired levels.
3. Set the monitor refresh rate to the optimal rate for the display at the desired resolution.
4. If necessary, adjust the image quality with the Sync Adjust switch on the send and receive baluns. It is recommended that both switches be in the same position.

Note: The AVO-VGA features an optional grounding screw that may be used to correct any image anomalies, such as differences in hue from one side of a monitor to the next. Should this occur, connect the balun ground to earth ground. However, if the building has a grounding problem, such as ground loops, grounding the balun may negatively affect the signal. Only ground the AVO-VGA if it positively affects the signal.

Troubleshooting

Symptom	Probable	Causes Possible Solut
Image distorted or skewed	Weak or distorted sync signal	Change the screen refresh rate of the video source to the next higher or lower setting
		Adjust the Sync Adjust switch on both the send and receive baluns
No image		Attach or detach the grounding screw on either or both of the baluns to earth ground
	Reversed polarity Unus	Verify RJ45 pinout conforms to EIA/TIA 568A or 568B standard. If not, re-crimp the cable.
	Bad RJ45 crimp
Smearing or weak video contrast	Exceeded cable distance	Verify cable grade and total cabling distance
		Reduce the screen resolution
		Reduce the screen refresh rate
Horizontal bars moving upward in background	Ground loop problem	Attach or detach the grounding screw on either or both of the baluns to earth ground
		Verify the source and destination equipment are at the same ground potential.
Shaking image		Change the screen refresh rate of the video source to the next higher or lower setting
Background pattern	EMI interference	Identify possible radiating frequency sources and isolate them from the cabling. Use shielded twisted pair cabling.
