About the MTP SW6 Switcher

The Extron MTP SW6 is a 6-input, 1-output mini twisted pair (MTP) switcher that is compatible with the entire line of Extron MTP transmitters and receivers.

The Extron MTP transmitters and receivers are a system for long-distance distribution of video and either audio or RS-232 communications. The MTPs transmit and receive over Extron’s Enhanced Skew-Free A/V UTP cable or over CAT 5, 5e, or 6 shielded twisted pair (STP), unshielded twisted pair (UTP), or foil shielded twisted pair (FTP) cable.

The MTP switcher receives up to six sets of signals from compatible MTP devices on RJ-45 connectors (figure 1-1). You can select one input to output to a compatible MTP device on an RJ-45 connector. The signal sets are comprised of high or low resolution video signals (RGB, bi-level or tri-level component video, S-video, or composite video) and can also include either RS-232 serial signals or audio.

The MTP switcher has image enhancement features that allow you to correct for long distance transmissions and skew:

•Level and Peaking controls enhance the TP signals received on the inputs.

•A Pre-Peaking control enhances the TP output for optimum display.

•Delay controls correct for skew delay (misconvergence) commonly encountered when using CAT 5, 5e, or 6 TP cables for RGB video, and component video transmission.

NSkew correction should not be necessary when Extron Enhanced Skew-Free A/V UTP cable is used and the transmission distance is less than 1,000' (300 m).

Bidirectional RS-232 signal from a dedicated source (rather than from the selected input) can be directly inserted into the signal set routed to the TP output. You can even route RS-232 on a link that is normally audio, such as to an MTP R 15HD RSA D receiver, which can autodetect whether

The MTP switcher is housed in a rack-mountable, 1U high, half rack-width metal enclosure. This switcher is shipped with an external 12 V power supply that accepts 100 to 240 VAC, 50 Hz or 60 Hz input and provides worldwide power compatibility.

NThe remote power capabilities of certain MTP models are not supported by this switcher.

NThe RS-232 Insert signal path is bidirectional.

The RS-232 link:

• Supports software flow control (XON, XOFF).

NHardware flow control is not supported.

•Supports full duplex and half duplex operation.

•Supports any baud rate (up to 38,400), data bits, parity, stop bits, and data format without configuration.

NHigher rates are possible, but performance will vary as a function of baud rate and TP cable length.
