INSTALLATION INSTRUCTIONS
794 & 797
INTERFACE MODULES
The Model 794 or 797 allows any of the Xantech 3-wire IR receivers, keypads and control systems to
connect directly to the serial remote control input jack found on many audio/video components. This
eliminates the need for attaching an emitter to the front panel of the unit. The installer, by choosing the
correct model number, suffix number and DIP switch settings, may use these modules to control many
components.
INSTALLATION
• Reviewalltables1,2,&3 tomakesureyouselectthecorrectinterface. Themodelnumbersuffixgenerally
specifies which INTERFACE CABLE is supplied with the unit (see Tables 1, 2 & 3).
• Do Not extend the cable supplied with the 794 or 797. The unit may not operate reliably when a longer
cable is used.
• Do Not plug the 794 or 797 into anything until all switches are set.
• There are ten DIP switches on the 794 and two on the 797. When the 794 or 797 is driven by a Model
390 Blast-IR or Model 792 Power Module, switch S1 must be in the 0 (off) position.
• The 794 and 797 are designed to supply power to Xantech 3-wire IR Receivers and keypads. Connect
them directly to the IN, GND1 and +12V terminals. The IN and GND1 terminals may also be connected
to any Xantech emitter output port.
• Use a 781RG or 782-00 power supply to power the 794 and 797 by plugging them into the +12V jack.

from the other device to the +12V and GND2 terminals on the 794 and 797.
• If the plug on the 781RG or 782 power supply does not fit the +12V jack on the 794 or 797, simply remove
the plug and connect the white striped wire to +12V and the black wire to GND2 on the 794 or 797
terminals.

• Switch S3 should be in the 1 (on) position in most
installations.

NOTES:
1. No connection to GND1.
2. Pioneer CD players, tape decks, projection TV's, etc., including newer receivers, require a wire
between the GND2 screw on the 794 and a ground screw on the Pioneer device.
3. May not be compatible with all models. Call Xantech for latest information.
4. Requires a wire between the GND2 screw on the 794 and a ground screw on the controlled device.
5. May require, on some models, a wire between the GND screw on Xantech Connecting Blocks and
a ground screw on the controlled device.
