Utilities located in:
$PAM/scripts: These require ‘set_project’ and an
appropriate $PAM/projects/$PROJECT/$OPS/channel_config
file
sdr_data_stats file channel summary
sdr_show_date file simple display of date/ttag
convert_sdr stn files
dump_sdr file provides message-by-message look
Utility located in: $PAM/bin/[ SunOS5sparc/Linuxi686/]
f_sdrdata –h for help, channel, station, raw, etc.
Allowed Cards: Use only Sandisk Compact Flash Cards, NOT microdrives!
Error Condition Indicator:
Normal Operation = LED blinks every second
Error Condition = LED blinks 'SOS' signal…when
rebooting.
Recovery: Under
normal circumstances, the watchdog timer should recover the operation from
spurious crashes. However if there are
problems with the CompactFlash (not inserted or it
failed) the error condition will occur: (continuous rebooting). In that case, remove power and check or
replace the CF with a fresh, empty, known-working media
Note: Removal
and re-insertion of a CF into the board will cause rebooting to occur.

System Clock / Baud Rate (Developer Note):
There are 2 Serial Baud Rates based on the System
Clock:
40Mhz clock: BootLoader=19200 Debugger=115kB
20Mhz clock: BootLoader=9600 Debugger=57600
These
are based upon the 'af_115_0.hex' debugger file located in: c\Tern\186\rom
Note you must change the output rate for the Debugger
/ project file before interacting and downloading
between these 2 FlashCore clock
rate board options.
Rt.
Click on project.axe file: select 'Target Expert'
Lft Click on experts 'configure settings': set correct
baud, click 'ok' and 'ok'
Rt.
Click on project axe file: build node
Then
go back to the expert to make sure the baud setting 'sticks'
You must also adjust user software as well,
specifically s0/s1_init.
For example, baud10=19.2 at 20Mhz
but baud=9 at 40Mhz clock.
Power
Consumption:
FlashCoreB: Regular, 40Mhz clock,
LM7805
FlashCoreB: LowPower, 20Mhz clock, LDO.
Note that the meter reading
was a bit inconsistent between running on the debug system and EVE.
I believe the higher number
based on the 40Mhz readings.
Note 1: Dividing clock
saves power, down to min. divisor of 128, however, any
interrupt will restore the clock,
and the 'serial-data-store' function utilizes serial
interrupts. Without revising the code
to poll the sio, it'll be the full freq. power drain.

Tern Board Wiring:
HOW-TO Change Tern Compact Flash Media:
Note: Basic Steps:
1)Setup PC to talk to EVE Console.
2)Stop Recording on Tern…see below, it is important to close the current file or recent data may
be lost.
3)Remove Compact Flash, Copy Files to PC, then erase files.
4)Install CF back into Recorder....This reboots /
restarts the recorder, make sure it's working.
Operator Steps: green indicates operator entered values. Comments are blue.
