UPGRADING THE FIRMWARE
TECHNICAL DESCRIPTION
8083XDS-AD Analog and SD-SDI XDS Encoder
5.5.1
Overview
The XDS 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
XDS Encoder.
•
Terminal program that is capable of Xmodem file transfer protocol.
(such as HyperTerminal)
•
New firmware supplied by Evertz.
The XDS 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 XDS encoder are
lower than those specified for the upgrade, Evertz technicians must 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
XDS 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
Flow Control
4. If you wish 38,400 baud communications, hold the
panel and apply power to the XDS encoder. For 9600 baud, hold the
key while applying power.
