1.0 Introduction

Thank you for purchasing this Cat 5 HDMI extender system from Audio Authority. The HDP-11 transmits HDMI signals over Cat 5e/6 cables to achieve distances many times those possible using an HDMI cable. The HDP-11 can achieve distances of 450 feet (150m) with 1080p and embedded 2-channel audio.

The HDP-11 employs a combination of digital and analog transmission methods over two Cat 5 cables (Cat 5, Cat 5e or Cat 6 Unshielded Twisted Pair (UTP) cables may be used). Cat 5 cable A carries the digital video and audio signals, and cable B carries the HDCP and DDC channels. When transmitting video signals that are not protected by HDCP, it is possible that only cable A may be required. Call Audio Authority technical support for details.

Audio Authority offers an extensive line of audio and video switchers, converters, and distribution amps available for purchase online at www.audioauthority.com or through authorized dealers.

2.0 Checking Package Contents

Before connecting the HDP-11, please make certain the following items are in the shipping carton. (If you purchased the 1381T or 1381R separately, ignore irrelevant items.)

• 1381T Transmitter
• 1381R Receiver
• 5V DC Power Adapter
• User Manual

Note: Please retain the original packing material in case you need to return the unit. If you find any items are missing, contact Audio Authority immediately. Have the model number and invoice available for reference when you call.

3.0 Installation

Before connecting the HDP-11 Cat 5 extender system, verify that the display device on the receiving end can support the output resolution and signal format by connecting it directly to the source device via a short, known good, HDMI cable.

The panel drawings below show the Cat 5 signal output/input connections, power connections and adjustable controls. (The HDMI input and output jacks on opposite end of each unit are not shown.)

• POWER: Power indicator light.
• 5V DC: Input for the 5V DC power adapter.
• CAT 5e/6 OUTPUT B: RJ-45 connector for Cat 5e/6 cable B (HDCP/DDC).
• CAT 5e/6 OUTPUT A: RJ-45 connector for Cat 5e/6 cable A (Video/Audio).
• HDMI INPUT: HDMI connector for the source device.

Receiver Model 1381R Panel Description

• POWER: Power indicator light.
• HDMI OUTPUT: HDMI connector for the display device.

3.1 Terminating Cat 5e/6 Cables

Use standard EIA-568A or B pairing, assigning low twist density pairs to the four center pins, and high density pairs to outside pins. Correct pairing is vital, and should always be checked with a network cable tester. The correct pairing is straight through, pin-to-pin, as shown.

Twist Density and Wire Pairing

The diagram shows RJ-45 connectors with pins facing up and latch down. It illustrates the EIA-568B standard for RJ-45 pin assignments (1 through 8). The diagram indicates sections with 'LOW DENSITY' and 'HIGH DENSITY' twists.

1381T End and 1381R End (Identical):

• Pins 1-2 and 7-8 should be assigned to high density twists.
• Pins 3-6 should be assigned to low density twists.

Cat 5e/6 cable pairs have different twist densities (twist pitches). There are two pairs with high density twist and two pairs with low density. Pairs 1-2 and 7-8 should be assigned to high density twists. Failure to assign correct twist densities can result in image jitter. Twist densities can be seen by stripping off about four inches of insulation.

Colors vary by manufacturer, so once you identify the high density twist pairs, use the chart below to assign the colors to the correct RJ-45 pins.

3.2 Connecting the Hardware

1. Connect the HDMI source device's output to the HDMI INPUT connector of the 1381T Transmitter, using a short, high quality, HDMI cable.
2. Connect a correctly terminated and tested Cat 5 cable to the Cat 5 Output A connector of the Transmitter. Connect a second Cat 5 cable to the Cat 5 Output B. Mark the cables at both ends so that you do not inadvertently swap them. Do not connect the AC adapter until the Cat 5 cables are correctly connected to both the transmitter and the receiver. Again, always test the HDMI source on the intended display with a known good HDMI cable before using the HDP-11. This precaution ensures that the source can be (and is) set to a resolution that is compatible with the display, and that both are functioning correctly together.
3. At the remote location, connect the appropriate Cat 5 cables to the Cat 5 Input A and B connectors of the 1381R Receiver. Be careful not to interchange the A and B cables. Cable A must be connected to both the transmitter and the receiver, and Cable B must be connected to the B inputs on both devices in most cases, depending on the source.
4. Connect the HDMI OUTPUT of the 1381R to the HDMI input of the video display or other device, using the appropriate cable.
5. Connect the supplied AC adapters first to the 1381T and 1381R and then to the AC outlets.
6. Turn on the source device and video display. The source video signal should appear on the display. If not, consult the Troubleshooting Guide in this manual.

4.0 Operating the Units

The Gain and Equalization controls on the 1381R Receiver should be adjusted to optimize the video signal for the Cat 5 cable length. Low Gain and Equalization settings are usually best for shorter cable runs, but receivers located at the end of cable runs near the limit of specified range may benefit from higher Equalization and/or Gain adjustments. It is best to make adjustments after permanent source and video display equipment is installed. EQ and Gain settings are retained by the Receiver even when power is removed.

4.1 Adjusting Equalization

Locate the EQ (Equalization) and GAIN adjustments on the side of the 1381R Receiver. The EQ control is at the top of the left side, and the Gain Control is just below it.

Symptoms: On long cable runs, the high frequency detail can be compromised, which appears as a "soft" or "smeared" picture. The effect is most evident in text and other hard, high contrast edges.

Adjust the EQ to sharpen the image. While viewing an image on a display connected to the 1381R Receiver, insert a small screwdriver into the EQ adjustment on the side panel of the 1381R. Turn the screwdriver gently until the image is optimal.

4.2 Adjusting Gain

If the image is too dark or too bright, insert the screwdriver into the Gain adjustment and rotate until the brightness of the image is optimal. When using long Cat 5 cables, you may notice an increase in video noise (sometimes called "snow") in the picture at higher gain settings.

5.0 Troubleshooting

• Poor image quality: See the previous section, Operating the Units.
• No surround sound (multi-channel audio): This system does not accept multi-channel digital audio; adjust the source to output 2-channel PCM digital audio.
• No picture: Perform the verifications below.
  • Check the HDMI cables at all four connections to see if any of the connectors have become loose.
  • Make certain the 1381T and 1381R are connected to live AC outlets and check the power indicators on both units.
  • Use a network cable tester to make certain your Cat 5/5e/6 cable is terminated correctly and the RJ-45 connectors are securely attached to the cable at both ends. Check for cable defects or damage.
  • Connect the display device directly to the source with the 1381T HDMI connection cable, then test with the 1381R connection cable. If an image is present under those circumstances, the display, the source, and the HDMI cables can be eliminated as the cause of the problem.
  • If the above circumstances do not produce a picture, try a short, known good HDMI cable, and make sure the source is set up to output a resolution that the display can accept.
