Xantech 797 Manuale Utente



1

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.

• Review all tables 1, 2, & 3  to make sure you select the correct interface.  The model number suffix generally

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 

 must be in the 

 (off) position.

• The 794 and 797 are designed to supply power to Xantech 3-wire IR Receivers and keypads.  Connect

them directly to the 

, 

 and 

 terminals.  The 

 and 

 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 

 jack.

You may also power them from other Xantech devices in a system by running +12 V and Gnd jumper leads
from the other device to the 

 and 

 terminals on the 794 and 797.

• If the plug on the 781RG or 782 power supply does not fit the 

 jack on the 794 or 797, simply remove

the plug and connect the white striped wire to 

 and the black wire to 

 on the 794 or 797

terminals.

• Switch 

 should be in the 

 (on) position in most

installations.

• When multiple 794’s are connected, or when ground

loops are encountered, set 

 to the 

 (off) position.

• Switch 

, and 

 through 

, should be set ac-

cording to Table 1, page 2.  For products not listed,
contact Xantech Technical  Support.  New versions
are added from time to time.

• Switch 

 should be in the 

 (on) position in most

installations.  When multiple 797’s are connected or
when ground loops are encountered, set 

 to the 

(off) position.

• In general, set 

 and 

 according to Table 2, next

page.  For products not listed, contact Xantech Tech-
nical  Support.   New versions are added from time to
time.
