Installation overview

To install and set up a CAT 5 receiver and the associated CAT 5 transmitter(s) for operation, perform the following steps:

Disconnect power from all of the equipment, including the

video source(s) (such as computers or DVD players), the transmitter, the receiver, and the output display(s).

For component, S-video, or composite video, ensure that

the internal jumpers are in the correct position (all except CAT 5 R AV). See Jumpers in this chapter.

Mount the receiver in a rack (CAT 5 R BNC A or

CAT 5 R BNC AV only), under a desk or podium, in a desk or table, or on a projector bracket. See the instructions that accompanied the mounting kit for specific information.

Connect the cable(s) between the CAT 5 transmitter(s) and

the receiver. See Transmitted signal cabling in this chapter and refer to the CAT 5 Transmitter Family User’s Manual, part #68-546-01.

Connect the output cables. See Output cabling in this

chapter.

Configure the CAT 5 transmitter(s). Refer to the CAT 5

Transmitter Family User’s Manual, part #68-546-01.

Connect power cords to the CAT 5 receiver, the CAT 5

transmitter, and turn on the video source(s) and the output display(s).

All CAT 5 transmitters include a 15V external power supply. The transmitters also receive power from the associated Extron CAT 5 receiver(s) via the CAT 5 cable. Extron recommends using the local power supply; however the power supply may not be necessary in some applications. Use the following guidelines:

• The CAT 5 T 15HD A, CAT 5 T 15HD AV, and CAT 5 T BNC may not require a local power supply for cable lengths of 300 feet or less.

• The CAT 5 T AV may not require a local power supply for cable lengths of 800 feet or less.

• The CAT 5 T BNC DA4 always requires the local power supply.

If problems are encountered, use the local power supply.

Adjust the picture controls on the front panel of the

transmitter(s) and receiver. See Front Panel Controls and

Cable testing

To ensure proper cable termination, each transmission cable system should be tested. Testing the cable from the RJ-45 connections at the transmitter and receiver gives the most accurate indications of cable problems.

There are two varieties of cable runs: simple runs, in which a single cable is terminated only at the transmitter and receiver, and complex runs, which can include patch bays and multiple terminations and lengths of cable. In either case, the entire cabling system should be tested.

A complete test measures cable length and tests the wire map, attenuation, NEXT, PSNEXT, ELFEXT, PSELFEXT, return loss, ACR and PSARC. All of these tests are critical for digital data transfer. While all of these tests are important indicators of the quality of the cable termination, the most critical testing parameters for video transfer are wire map (T-568-A termination) and pair length measurements. The largest concern is equalization of skew between cable pairs. Cable systems of 300 feet or less should exhibit no transmission problems if they pass at least CAT 5e or preferably CAT 6-D5 channel certification testing.

The Microtest OMNI SCANNER 2 performs comprehensive certification testing to the proposed CAT 6 standards. Other manufacturers also make testing equipment. The tests include advanced diagnostics for troubleshooting the cause and location of many cable and termination problems. For simple installation testing, the Microtest MICRO SCANNER PRO tests

wire map and cable length, including individual cable pair length.

Equalizing pair skew

The manufacturing process for UTP cable leads to a condition called pair skew. Skew exists between pairs when the physical length of one wire pair is different from another. As the transmission cable length increases, the amount of skew increases. Skew affects the displayed image when the differential length between wire pairs exceeds 2 feet, causing the timing of the red, green, and blue video signals to appear out of alignment (horizontal registration errors). A white vertical line on a black field can appear as individual red, green, and blue lines that are close together; the signal transmitted on the shortest wire pair leads the other colors and appears to the left on the display.

UTP cable test equipment measures and reports wire pair length. The report on the various pair lengths can be used in equalizing pair skew. The nominal velocity of propagation (NVP — the speed at which the signal travels on the transmission line, measured as a percentage of the speed of light) is very close to that of conventional coaxial cable. The similarity in NVP means that an additional length of coax equal to the length of pair skew, placed on the receiver’s output, equalizes the effects of pair skew (figure 2-4).

If UTP cable test measurement cannot be done, pair skew can still be equalized by viewing a test pattern with a critical eye. Examine the test pattern for loss of horizontal registration and, through a process of trial and error, equalize any pair skew with coax extensions on the red, green, and/or blue outputs.

Troubleshooting

If the image does not appear

1. Ensure that all devices are receiving power. The

transmitter’s and receiver’s front panel Power LEDs indicate that they are receiving power.

2. Ensure that the transmitter is receiving a video input.

3. Ensure that the CAT 5 cable(s) are properly terminated in

accordance with TIA/EIA T 568A standards and that the RJ-45 connections are securely made. If the Power LEDs on the transmitter and the receiver are lit green, a transmitter is properly connected to a receiver.

4. For computer/RGB video, ensure that the receiver’s SOG

and C Sync switches are in the correct positions for the video output.

5. For computer video, ensure that the transmitter’s ID bit

switches are on.

6. For computer video on an LCD projector, ensure that the

transmitter’s DDSP switch is on.

7. The transmission distance may be too far for remote

power. Try connecting the local 15V power supply to the transmitter.

8. The transmission distance may be too short. Ensure that

the UTP cable is at least 50 feet long.

9. If the Manual/Auto switch is in the manual position,

ensure that the receiver’s level controls are not set too high. Too much level and peaking can cause display problems.

10. For computer video from a laptop or for ungrounded AC

distribution systems, the transmitter may need to be grounded. See Grounding the transmitter in the CAT 5 Transmitter Family User’s Manual, part #68-546-01.

11. Call the Extron S

necessary.

Sales & Technical Support Hotline if

If the image is not displayed correctly

1. For computer/RGB video, if the output image looks too

green, ensure that the receiver’s SOG switch is off.

2. For computer video, if the picture hangs off the edge of the

screen, adjust the transmitter’s H Shift control.

DDSP disables the horizontal shift control.

3. Place the receiver’s Manual/Auto switch to manual and

adjust the level and peaking controls for optimum quality.

4. The transmission distance may be too far for remote

power. Try connecting the local 15V power supply to the transmitter.

5. For computer video from a laptop or for ungrounded AC

distribution systems, the transmitter may need to be grounded. See Grounding the transmitter in the CAT 5 Transmitter Family User’s Manual, part #68-546-01.

6. If the image still does not display properly, call the Extron

Sales & Technical Support Hotline.

If the receiver’s Manual/Auto LED flashes

1. The transmission distance may be too far for remote power.

Connect the local 15V power supply to the transmitter.

2. Check the RJ-45 connector for a loose connection.
