About the MTP Transmitters and Receivers
The Extron MTP T 15HD RS transmitter and MTP RL 15HD RS and MTP RL 15HD RS SEQ
receivers are a system for long-distance distribution of VGA or other high resolution video
and RS-232 serial communications.
The MTPs are a part of the Extron compact line of basic distribution amplifiers, switchers,
transmitters, receivers, and associated video accessories.
High resolution video is sent to the MTP transmitter on a 15-pin HD connector. The
transmitter passes RS-232 serial data or control signals on a 3.5 mm 3-pin captive screw
connector. The transmitter converts the video and RS-232 signals to proprietary signals and
outputs them to a compatible MTP receiver on an RJ-45 connector. The transmitter also
makes the input video available for local use on a 15-pin HD connector.
The transmitted proprietary signal is sent to the receiver on an RJ-45 connector and converts
the signal back into its high resolution video and serial data components. The receiver
outputs the video on a 15-pin HD connector. The serial communications are passed on a
3.5 mm 3-pin captive screw connector.
The RS-232 portion of the TP link:
z z Can be bidirectional in a one-receiver system; that is, the receiver can receive commands
from the transmitter and pass RS-232 responses to the transmitter.
NOTE: If there is only one receiver in the system, you can shift a jumper in that
receiver (see " Receiver Jumpering " on page 5) to allow bidirectional
RS-232 communications and change a DIP switch setting (see " End Unit
switch " on page 12 to properly terminate the signal).
z z Supports software flow control (XON, XOFF).
NOTE: Hardware flow control is not supported.
z z Supports full duplex and half duplex operation.
z z Supports any baud rate (up to 38,400), data bits, parity, stop bits, and data format
without configuration.
NOTE: Higher rates are possible, but performance will vary as a function of baud
rate and TP cable length.
The receiver also buffers the proprietary input signal and sends it to another compatible
MTP receiver or to a daisy chain of receivers.
NOTES: • The transmitter provides pre-peaking, which boosts the signal before it is
transmitted. The buffered output on the receiver does not provide any
pre-peaking control. The total recommended distance (see the
table on
page 4) for an entire daisy chain is the same as for a single transmitter and
receiver. The Pre-Peak switch on the transmitter has the same affect on
the recommended transmission distance for a daisy chain as for a single
transmitter and receiver.
• Up to eight receivers can be connected in series using the Buffered
Output connectors, provided that the total distance from the TP output
of the transmitter to the last receiver in the chain does not exceed the
recommended distance for the resolution being used.
