UPGRADING THE FIRMWARE
Most upgrades will cause user settings in the caption encoder to revert to
factory defaults.
menu settings prior to upgrading the firmware. You will have to restore
them manually after the firmware upgrade. You will also have to re-initialize
any XDS packets and articles that you have in memory using the MetaCast 2
or CaptionWare software. (you may download a free demo copy of
CaptionWare from http://www.evertz.com)
TECHNICAL DESCRIPTION
Models 8084/8084AD/8085 Closed Caption Encoder Manual
5.5.1
Overview
The Caption Encoder contains firmware in a FLASH ROM device. From
time to time firmware updates may be provided to add additional features
to the unit. The following procedure will allow you to upload new firmware
from your computer.
You will need the following equipment in order to update the Firmware:
•
PC with available communications port. The communication speed
is selectable between 9600 baud and 38,400 baud. A 486 PC or
better with a 16550 UART based communications port is
recommended.
•
"Null-modem" serial extension cable (DB9 female to DB9 female) or
(DB25 female to DB9 female). This assumes that the user has not
changed the pinout of serial port A using the jumpers inside the
Closed Caption Encoder.
•
Terminal program that is capable of Xmodem file transfer protocol.
(such as HyperTerminal)
•
New firmware supplied by Evertz.
Evertz recommends that you make note of your setup
The caption encoder also contains instructions in programmable logic
devices (PLDs). The PLDs are not field-upgradeable. Very rarely, a
particular device upgrade may specify a minimum PLD revision number in
addition to a firmware upgrade. If the PLD revision numbers in the caption
encoder are lower than those specified for the upgrade, Evertz technicians
must be service the encoder to perform the upgrade.
5.5.2 Procedure for Firmware Upgrades
1. With power disconnected, connect the null-modem cable between the
Closed Caption Encoder serial port A and the PC.
2. Power-up the PC, and start the terminal software.
3. Configure the port settings of the terminal program as follows:
Baud
Parity
Data bits
Stop bits
