INSTALLATION INSTRUCTIONS
Fig.1 792-10 Power Module
The 792-10 is a multipurpose device designed for use in the
following applications:
1. As an output amplifier and power source to convert
Xantech 3-wire IR Receivers to 2-wire PHANTOM
POWER operation.
2. As an output amplifier for any Xantech IR Receiver or
Controller to drive large numbers of emitters when
plugged into one or more 790-00 passive Connecting
Blocks.
FEATURES AND SPECIFICATIONS
• Phantom Power and/or Current booster modes.
• Phantom mode powers the 291-10, 480-00, 490 and 780-10 series IR receivers for 2-wire operation.
• Screw terminals provide for wired input connections.
• 3.5 mm mono mini jack emitter IR OUT port.
• Low current mode drives up to 4 emitters in series.
• High current mode drives up to 100 emitters in parallel through 790-00 Connecting Blocks.
• Maximum peak output current - Low Current mode: 100 mA.
• Maximum peak output current - High Current mode: 1 A.
• 2.1mm coaxial DC power jack (+12V).
• Requires a 781RG or a 782-00 power supply.
• Dimensions: 3-5/8" L x 1-5/8" W x 1" D.
GENERAL
The input and output parameters for setting Normal 3-wire, Phantom 2-wire and Output Current modes are
configured by setting the DIP switches. These switches are accessible through the slot in the case.
• In the Normal 3-Wire mode, +12V is applied to Xantech IR Receivers and Keypads on a third wire in the
same manner as on Xantech Connecting Blocks.
• In the Phantom 2-Wire mode, +12V is applied to the IR Receivers on the same wire that carries the IR
control signal.
PLEASE NOTE:
The Xantech Smart Pads and the CFL Friendly IR receivers, will not operate with
the 2-wire Phantom Power connection!
• In the Low Current mode, the 792-10 IR OUT jack will drive a single or dual emitter or connecting blocks
in the same manner as an IR receiver.
• In the High Current mode the 792-10 IR OUT jack will drive up to 10 Model 790-00 Connecting Blocks,
each having up to ten emitters connected to it.
CAUTION:
Do not plug single or dual emitters into the IR OUT jack when the 792-10 dip switches
are set to the High Current mode. To do so will destroy emitters!

INSTALLATION
Set the DIP switches to the desired mode, using the chart below. Check your settings carefully to be sure
they are correct.
NOTE:
Do not connect the power supply until all switches are set & all other connections are made.
Phantom Power Connections
Some existing installations may have only 2 wires (such as coax) going to a remote room. Fig. 3 illustrates
Phantom Power connections in a basic system:
• Although a 780-10 is shown, other Xantech 3-wire IR Receivers may be used.
• In each case, the OUTPUT and GND leads of
the IR receiver are jumpered together and
connected, through the inter-room cable, to
the GND terminal of the 792. The +12V lead
is connected to the IN terminal of the 792.
• Additional 780's or other Xantech IR Receiv-
ers may be wired in parallel at the IN and GND
terminals of the 792, up to a maximum of
three. More than this may cause unreliable
results.
• If you have more than three IR receivers, connect additional 792-10's as shown in Fig. 4
NOTE: Phantom power mode is not recommended unless faced with an existing coax or other 2-wire
situation. For new construction, always pull three wires and use the normal 3-wire connections for best IR
operation.
Multiple-Emitter High Current Operation
The high current output capability of the 792-10
allows up to 100 single or 100 dual emitters to be
driven. Fig. 5 illustrates the necessary connec-
tions:
• The IR OUT jack of the 792-10 is connected to
multiple 790-00 Connecting Blocks as shown.
(The output of the 792-10 is also available
between the IR OUT and GND screw termi-
nals,intheeventawiredconnectionisneeded.)
• Set the DIP switches to the 3-Wire High Cur-
rent mode. Refer to Fig 2.
• A high current power supply, model 782-00, is used to supply the high peak currents required.
MOUNTING - Holes are provided in the end flanges of the 792-10 for mounting. Use the 2 screws provided
to secure it to any flat surface.
NOTE: With any of these systems, be sure the power supply is plugged into an un-switched AC outlet. This
maintains the IR system in "standby" operation so that power-on commands can be sent to the controlled
equipment.
