REVISION SUMMARY
APPENDIX C REVISION SUMMARY
C.1 OPERATING SOFTWARE REVISIONS
The operating (Flash) software version can be
determined as described in Section 3.12.4. The
following is a summary of changes made for recent
revisions:
Version 210 - Released 9/99 For Low/Mid/High/Data
Tier Models
• With high and data tier models, corrected an error in
a serial interface message relating to display
information.
• With low and mid tier models, corrected a problem
with displaying the software revision number.
Version 209 - Released 8/99 For Low/Mid/High/Data
Tier Models
• Change squelch operation to use RSSI signal as well
as noise signal (similar to LTR-Net models). This
capability is available only with versions that have
the revised squelch circuit (see Section C.4). The
software automatically detects a revised transceiver
from a marker in the logic that indicates that the
radio has the change. If this marker is not present, it
is assumed that it has the unrevised squelch circuit
and the standard squelch algorithm is used.
• Made serial interface updates and enhancements
• Added support for channel tables 2 and 3 in LTR and
conventional systems (high and data tier only)
Version 208 - Released 6/99 For Low Tier Models
Only
• Increased squelch adjust range during conventional
operation

tier only)

with this device except some early mid tier models
