Subsequent IR commands specific to
the TV's, such as channel Up/Down,
then operate the functions of the TV or
TV's addressed.
7. In this system, the RC68+ codes are
"taught" to a Xantech URC type Learn-
ing Remote for use with the 480 Dinky
Link™ IR Receiver and to the Xantech
SmartPad. Other learning devices may
be used provided they are capable of
learning and outputting the RC68+
codes, with carrier, to the RT8.
8. When programming, begin by assign-
ing 6 keys to a keypad or a learning
device for the RC68+ commands.
In this case, these would be commands
1, 2, 3, & 4 for individual routing and the
GP-ON and GP-OFF commands. Next,
assign keys for the TV function com-
mands, such as channel Up/Down.
NOTE: Since GP-ON is cancelled when
any one of the individual commands is
subsequently sent, you could eliminate
the GP-OFF command. This will save
you one key on the learning device.
9. Teach the commands into the assigned
keys, following the instructions that
come with the learning device. On URC
type remotes and the Xantech Smart
Pad, all these commands could go into
one bank.
10. The "I" and "G" terminals on each of the
output terminal jacks are provided so
that LED indicators, placed near each
TV Monitor (if desired) will give a visual indication of the currently controlled Monitor. Refer to Fig. 5.
Use LED's with an operating current rating of 10 to 20 mA.
Fig. 6 shows a typical system whith four same-brand satellite receivers individually controlled from four
remote room locations.
1. Using the Xantech "Xtra Link™" patented principle, CPL10 RF/IR Couplers and INJ94 Injectors are
used to inject the IR signals onto the coaxial cable at the remote TV rooms and are extracted at the
other end to drive the emitters, selectively, at each satellite receiver through the RT8 Router.
2. A variety of Xantech IR Receivers and a keypad are shown in the remote rooms to illustrate the
flexibility of the system.
3. An RF Amp, such as the Channel Plus DA500 in the RF system, overcomes the RF signal losses of
the RF splitters and the long cable lengths.
4. A 789-44 Connecting Block is shown expanding the control signal from the IR jack on the CPL10
Coupler to the RT8 and to emitters on other controlled devices. If you need to drive even more emitters,
use the 791-44 Amplified Connecting Block instead of the 789-44.
