Chapter 10: Troubleshooting
Operational problems with the Omnia-3 can sometimes be diagnosed using the rear-panel RS-232 port and a
common terminal communications program. Detailed information about the Omnia's boot-up progress may be
observed at its rear-panel RS-232 port, as well as viewing of any error messages that may be encountered. This
chapter explains the various boot up and error messages that may be encountered while troubleshooting the unit.
We'll cover some basic troubleshooting techniques for isolating possible Omnia-3 problems in the field, and
also how to obtain help or repair service from Omnia.
To take complete advantage of this functionality, you only need a standard terminal program for DOS,
Windows, or other operating system. It must be configured for a default baud rate of 19200, no hardware
handshaking, and using a terminal emulation for VT100. At Omnia, we commonly use the Hyperterminal

, but you can use whatever program you are familiar with. Please
see the examples below for how we've set up our connection:
Port Setup Parameters
Terminal Emulation Parameters
Once these parameters have been entered and saved as a connection profile, they can be used to capture and
display (and print) the output of the Omnia 3's RS-232 serial port during boot up. See the next page for an
example of a normal Omnia-3 boot up...
