Extron Electronics DVI 201xi Tx User Guide - Manual (Page 13)

RS-232 signals
RS-232 signals are bidirectional – signals pass from the control
device and replies return from the remote device. To connect the
control device to the transmitter or the receiver to the remote
device, make the following connections:
z z
Tx is connected to Tx.
z z
Rx is connected to Rx.
z z
Ground ( ) is connected to ground.
NOTE: For information about controlling display devices
with RS-232 commands, see the user manual for
that device.
IR signals
IR signals are one-way (from control device to the IR emitter bug
that will broadcast the IR signal remotely). There are no responses
and no requirement for a reverse pathway. To connect the control
device to the transmitter or the receiver to the IR emitter, make the
following connections:
z z
The Signal (S), from the control device, is connected to Tx of
the transmitter.
z z
The ground (G) of the control device is connected to the
ground ( ) of the transmitter.
z z
The Tx of the receiver is connected to the S of the IR emitter.
z z
The ground of the receiver is connected to the ground of the IR emitter.
Twisted Pair Output
h
Twisted pair outputs — Two RJ-45 jacks are used for transmitting DVI video, remote
power, and communications or control signals.
Terminating shielded cable
CAT 5, 5e, or 6 twisted pair cables or Extron DTP26 cables are not provided with the
transmitter and receiver pair. You may purchase cables that have been precut to the required
length and terminated to the T586A or T586B standard (see the table on the following
page). Alternatively you may purchase bulk cable and RJ-45 connectors, and prepare your
own terminated cables by following the instructions below:
NOTES: The transmitter and receiver pair works with unshielded twisted pair (UTP) or
shielded twisted pair (STP) cables. To ensure FCC Class A and CE compliance,
and for optimum performance, STP cables are recommended.
Do not use Extron Skew-Free™ cable with this product.
