Appendix F Diagnostics
The BD500 has software features designed to aid
debugging the system hardware. Some of these fea-
tures may be used to assist in analyzing end-user setup
problems or in diagnosing user or off site technician
serviceable components. This section includes a break-
down of different operations that the broadcast delay
does during power-up and while changing operation
modes. In addition, the 'hidden' start-up modes and
system hardware failure messages are described.
Disclaimer: This information is correct at the time
of this manual's publication (before release of version
2.5 of the BD500 software.)
Start-up Sequence
•
Reset front panel (turns all lights on)
•
Turn off DS113 motherboard LED, then flash it on,
then off again
•
Turn off option board Remote Control Connector and
Auxiliary Connector outputs
•
Turn on DS113
•
Cycle through the seven motherboard status LEDs
from #2-0 to #2-6
•
Turn off DS113
•
Test the firmware ROMs - if fail, flash motherboard
status LED #2-0 indefinitely - if pass, light mother-
board status LED #2-0 indefinitely, then scan the rest
of the LEDs once - the front panel will stay all-lights-
on indefinitely if failure
•
Test the motherboard RAM - if fail, flash motherboard
status LED #2-1 indefinitely - if pass, light mother-
board status LED #2-1 indefinitely, then scan the rest
of the LEDs once - the front panel will stay all-lights-
on indefinitely if failure
•
Initialize motherboard RAM
•
Flash motherboard status LEDs #2-4, #2-5 and #2-6
three times quickly, leaving them off
•
Turn on DS113 motherboard LED
•
Declare that we are not in run-time mode for Remote
Control Connector status outputs
•
Begin "STARTUP"
•
Initialize Remote Control Connector outputs, not in
run-time.
•
Set audio bypass relay (redundant)
•
Initialize RS-232 connector on option card.
•
Initialize front panel (turns off DUMP light, meters
and delay bar graph) - after this point diagnostics may
be displayed on the front panel if a failure occurs (may
be disabled in configuration)
•
Display version message
•
Check that motherboard memory was initialized.
•
Check if unit has jumper for production self test - if yes,
begin "TEST FIXTURE" and run test fixture forever
•
Initialize AtoD converter used to measure power sup-
ply voltage.
•
Put up "
TST
" message.
•
Check power supply voltage. If measures out of range,
display error message.
•
Check and load the battery backed memory configura-
tion values.
•
Initialize all configuration values (delay amount LEDs
run all over the place during this process). If a reorga-
nization of the configuration values is required (due to
software upgrade) set all values to factory defaults
here.
•
Check if user is holding WAIT AND EXIT button - if
so, put up "
RELEASE
" message and turn off 'hide fatal
error mode', then resume.
•
Test and initialize DSP coprocessor and audio section.
•
check for presence of DSP coprocessor.
•
init audio section.
•
upload coprocessor OS
•
test DSP coprocessor to main processor communi-
cations
•
upload 1st memory test to coprocessor, test com-
munications, then run test.
•
upload 2nd memory test to coprocessor, test com-
munications, then run test.
•
using results of 2nd memory test, set memory size
•
upload coprocessor OS for the 2nd time and test
communications.
•
check analog clocks.
•
load and find version numbers of PFD and profan-
ity delay coprocessor firmware
•
set up input and output level controls on coproces-
sor.
•
Check if user is holding any button besides DUMP and
WAIT AND EXIT and SNEEZE
•
If so, display "
RELEASE
" message.
•
If user was holding CONFIGURE, display "
FAC-
TORY DEFAULTS
", reset factory defaults and then
continue with startup.
•
If user was holding BYPASS, display "
TESTS
", and
then proceed into the production self-test system
(this will fail if loopback cables are not installed,
but not before testing RAM, EPROM, NVR, DSP
memory.
•
If user is holding REBUILD button, enter menu
to select startup delay mode.
•
If user was holding any other button, display "
NO
SUCH FUNCTION
" and then continue with startup.
•
If production self test is enabled by configuration, do
the test now
•
Initialize the User Interface
•
Enable RS-232
•
Enter "RUNTIME" mode
•
Start User Interface
•
Check
PUP
variable and start processing audio if en-
abled
