TECHNICAL DESCRIPTION
Models 8084/8084AD/8085 Closed Caption Encoder Manual
10. The following is a list of possible reasons for a failed file transfer:
•
The supplied "*.HEX" file is corrupt.
•
Wrong file specified to be uploaded.
•
The PCs' RS-232 communications port can't handle a port speed of
38400bps.
11. To complete the upgrade, either select "Quit" from the terminal menu,
or power-down the unit and reapply power without pressing any keys to
resume normal operation. If the Flash ROM contains valid code, the
unit will resume normal operations. If there is a problem in the new
firmware, you will be prompted with an error message and remain in the
bootloader.
5.5.3
Viewing Firmware and PLD Revision Levels
Your Evertz caption encoder does not need to be taken out of service to
check the firmware or PLD revision levels. These can be checked from the
front panel display. The serial port configuration and power supply status
can also be checked from these front panel displays.
To view the firmware revision, the encoder should be running in the normal
operating display. Press SHIFT+SELECT keys. The alphanumeric display
will cycle through the following messages (or similar):
This is the name of the HEX file that was downloaded to the
CK88D5
caption encoder.
This is the file date of the last "released" version of firmware. In
000724
this case it is 2000, July 24.
R000724 This is the actual firmware revision for the closed caption
encoder. If the first character is a 'U' instead of an 'R' then the
caption encoder contains unreleased beta firmware. (Evertz
does not ship unreleased caption encoder firmware, except
where customers have requested special features.)
A232 B232 C232 Indicates the logic levels of the three internal serial
ports for diagnostic purposes. These may be either "232" or
"422" for each port. Port A may also display "???" because it
was not possible to read-back this data from earlier revisions of
the IO PLD.
--- PtE MON S12 This display shows features installed in the caption
encoder. In this case, PtE stands for modem Port E, and MON
is the 9000CME monitor/decoder (which is standard issue in
8084 and 8084AD). Units equipped with an 8058 submodule
and dual power supplies also display the status of the power
supplies here. The digits '1' and/or '2' appearing next to the 'S'
indicate which supplies have power applied.
