Extron electronic MTP DA4 Front Panel Power Indicator, Skew Delay Problems, Specifications, Video

VersaTools® MTP DA4 and MTP DA8, cont’d

Enhanced Skew-free A/V cable is not recommended for

Ethernet/LAN applications.

This cable is specially designed for compatibility with

Extron’s Twisted Pair products, wired using the

TIA/EIA 568 A standard.

The green, brown, and blue pairs of this cable have virtually identical lengths and should be used to transmit the RGB, composite video, or S-video signals.

The orange pair of this cable has a different length and should not be used to transmit the RGB, composite video, or S-video signals.

If you are using the DA as part of an MTP 15HD RS (serial data) transmission system, be aware that the DA routes the serial link one way only, from the transmitter to the receiver(s).

Also, the transmitter and receiver must be jumper configured to pass the serial link one way only. Refer to the MTP 15HD RS user manual.

Skew Delay Problems

CAT 5 TP cable can lead to registration errors between the red, green, and blue video signals. Pair skew can be measured with test equipment or identified by viewing a crosshatch test pattern with a critical eye to determine if either the red, green, or blue video image leads (appears to the left of) the other two video images. These images can be minimized or eliminated by one of the following methods:

•Using a skew delay adjusting receiver:

(MTP RL 15HD A SEQ or MTP RL 15HD RS SEQ)

•Switching to Extron’s Enhanced Skew-Free A/V UTP cable

•Adding a skew compensation cable equal to the length of pair skew to the receiver’s video output

•Installing an SEQ 100 BNC Skew Equalizer on the receiver’s video output and adjusting the skew for the leading video image
