Extron electronics MTP 4T 15HD RS User Manual page 7

The RS-232 portion of the TP link:
Can be bidirectional in each system that includes just one receiver (not a daisy
•
chain); that is, the receiver can receive commands from the transmitter and pass
RS-232 responses back to the transmitter.
NOTE:
By default, the RS-232 portion of the TP link is unidirectional only,
from the transmitter to the receiver. If there is only one receiver in
the system, you can configure that receiver for bidirectional RS-232
communications. Refer to the MTP 15HD RS Series User Guide.
Supports software flow control (XON, XOFF).
•
NOTE: Hardware 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.
NOTE:
Higher rates are possible, but performance will vary as a function of
baud rate and TP cable length.
Up to eight receivers can be connected in series to a single transmitter, provided that the
total distance from the transmitter's TP output to the last receiver in the chain does not
exceed the recommended distance for the resolution being used.
NOTE:
Each individual transmitter provides pre-peaking, which boosts the signal before
it is transmitted. The receiver does not provide any pre-peaking control. The
total recommended distance (see page 3) for an entire daisy chain is the same as
for a single transmitter and receiver. The transmitter's Pre-Peak switch has the
same effect on the recommended transmission distance for a daisy chain as for a
single transmitter and receiver.
The SEQ version of the receiver also corrects the skew delay (misconvergence) commonly
encountered when using CAT 5, 5e, or 6 TP cables for RGB video and component video
transmission.
NOTE: An SEQ receiver should not be necessary when Extron Enhanced Skew-Free AV
UTP cable is used.
All four transmitters in the MTP 4T 15HD RS are powered by a single internal 100 VAC to
240 VAC, 50/60 Hz, 20 watts power supply that provides worldwide power compatibility.
