Extron electronic TP T A 45, TP T 15HD 45 Compatibilty with other Extron products, Cable testing

Installation, cont’d

2Connect the TP T 15HD 45 and its receiver to either end of the UTP cable. See Cable testing and Skew delay problems in this chapter.

For best results, use Extron Skew-Free™ A/V UTP cable available in bulk or in various preterminated lengths. If necessary, regular CAT 5, CAT 5e, and CAT 6 cable may be used.

3Connect the external power supply to the TP T 15HD 45 and TP T A 45 (if installed). See Rear Panel Connectors in this chapter.

4If the TP T A 45 is being installed, connect the TP T A 45 to the transmitter. See Rear Panel Connectors in this chapter.

5Connect an output display device to the output connector of the receiver.

6Connect a computer to the 15-pin video input connector of the transmitter.

7Connect and power up all input and output devices, then apply power to the TP T 15HD 45 power supply and test for the display and/or audio outputs. If a problem is encountered, check all connections before proceeding further.

8If the previous display and/or audio test was successful, power off and disconnect all equipment, detach cables, and install the TP T 15HD 45 and/or TP T A 45 modules. See Mounting in this chapter.

If the transmitter or receiver is to be wall-mounted and the power supply will be inaccessible, power must be applied to the power supply before final mounting.

9Connect all device and power cables. Power up all input and output devices, apply power to the transmitter and receiver, and test for the display and/or audio.

•TPX 88

Cable testing

To ensure proper cable termination, each transmission cable system that uses CAT 5e or CAT 6 cable should be tested (Extron Skew-Free™ A/V UTP cable does not need to be tested). Testing the cable from 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 PSACR. 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 or T-568-B 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.
