4.2.2 AC Power Fluctuating
If the system periodically displays a picture for less than one
minute, then enters Search Mode 1, the IRD data port may be
locked up as the result of power fluctuations and will require a
reset. This can be verified by hooking up a PC to the maintenance
port and checking for error messages. Reset must be done by:
1. Completely shutting down DC power to the
antenna.
2. Remove the AC source, either at the breaker or by
unplugging the IRD.
3. Wait at least 10 seconds before restoring power,
first to the IRD and then to the antenna.
4.2.3 No IRD Data Connection
To view status messages, your TracVision antenna must be
connected to the IRD’s low-speed data port. Refer to
Section 2.3.4, “Connecting the Switchplate to the IRD” for details.
4.2.4 EchoStar IRD Activation Check
If you have purchased a DISH Network system, there is a chance
that your EchoStar IRD will fail to acquire the satellite when you
first activate it. This has been known to happen in IRDs that have
not been activated within several months of their manufacture.
Appendix D provides the manual satellite acquisition and
activation procedure.

A Guide to TracVision S2
The long-term fix, typically done at
original system installation, is to
install an Uninterruptible Power
Supply (like those available for use
with computer systems) on the IRD.
Be sure to specify a UPS with
adequate available current for all
devices attached to it. (An IRD
draws approximately 200 watts.)
