pass-through data lines, connect desired devices to
the transmitter and receiver units. For RS-232, use
serial cables and the supplied 3-pin Phoenix Connectors
to connect a controller unit (e.g. touch panel) and serial
controlled device (e.g. projector) to the RS-232 ports on
the Tx and Rx. Please see the drawing of the female
Phoenix Connector on the unit for RS-232 pin definitions.
These extenders support bidirectional IR using two independent IR signals. An
IR signal may be extended over the CAT-X cable from the Tx Unit to the Rx Unit
by doing the following. Connect the supplied IR Receiver to the IR IN port of the
Tx Unit. Next, connect the supplied IR Transmitter to the IR OUT port on the Rx
Unit. To send an IR signal in the opposite direction (i.e. from Rx to Tx), simply
connect the IR Receiver to the IR IN on the Rx Unit and the IR Transmitter to the
IR OUT on the Tx Unit.
The DVI-7525 extender pair supports extension of 100BaseT Ethernet over the
CAT-X cable. Take care to only connect compatible devices to the ports marked
“Ethernet” on the rear of the DVI-7525 extender pair. Connecting Ethernet devices
to the HDBaseT ports or connecting HDBaseT devices to the Ethernet ports may
result in damage. Please see the warning at the bottom of page 6.
4.2 Power Connections and POH Remote Power
The DVI-7520 and DVI-7525 are fully compliant with the Power over HDBaseT
(POH) component of the HDBaseT standard. During POH operation, the
transmitter unit functions as a PSE (Power Sourcing Equipment) device that
The right pin is the Ground
when facing the unit.
