Appendix C. DATA COLLECTION

C.1

Data Collection Overview

This appendix provides you with the necessary steps that you must follow to collect diagnostic
information from an onsite (field-installed) CDM-840 Remote Router. Should you experience an
operational issue (such as degraded performance or loss of IP access), it is mandatory that you
collect this diagnostic information from the onsite unit in question before contacting Comtech
EF Data Product Support. Comtech EF Data can then use this information to properly investigate
and resolve the issue.
The procedures described here require that you use a user-supplied, Windows-based PC,
equipped with a user-supplied terminal emulation program (e.g., Tera Term or HyperTerminal),
and a custom Serial Adapter Cable
details about your initial setup requirements.
Once you are properly configured for data collection, you must do these steps, in this order :
1. Sect. C.3 instructs you to obtain pre-reboot information* from the onsite CDM-840. You will
use your User PC terminal emulator to perform a text capture. Use the emulator to access
the CDM-840 Serial Interface, for serial communication between the CDM-840 and your
User PC. An example of the Serial Interface is shown here (your firmware revision letter and
version number may differ):

See Sect. C.5 in this appendix for the specifications required to fabricate the Serial Adapter
Cable that must be provided by the user for use in this procedure.

to connect your User PC to the CDM-840. See Sect.

CDM-840 for any reason until otherwise instructed in this appendix.
