4.2 EchoStar IRD Commissioning
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 commissioned within several months
of their manufacture. Appendix E provides the manual satellite
acquisition and commissioning procedure.
4.3 Antenna Gyro and LNB Faults
Section 5, “Maintenance,” provides detailed instructions for
authorized service personnel who may be required to replace the
TracVision 4 antenna gyro or the LNB.
4.4 Computer Diagnostics
TracVision 4 has been designed to provide diagnostic readouts
viewed on a personal computer having an RS-232 serial
communication port. If you are unable to isolate a system
problem, set up for computer diagnostics as described below.
System problems will most likely be found somewhere through
the diagnostic readouts.
The diagnostics procedure requires terminal emulation software
such as PROCOMM, Windows Terminal, or Windows 95/98
Hyperterminal. Use the settings appropriate to your application.
1. Connect one end of the PC cable to the DB9
connector on the switchplate. Connect the other
end to the serial port on the PC (a 9-pin/25-pin
connector adapter may be needed for some PCs).
2. Open the terminal emulation software and
establish the following settings:
• 9600 baud
• no parity
• 8 data bits
• 1 start bit
• 1 stop bit
• no flow control
