UPGRADING THE FIRMWARE - RS232 SERIAL PORT
Overview
5.2.1.
The firmware in the downstream keyer units is contained on a FLASH EPROM. Occasionally, firmware
updates will be provided to add additional features to the units. The router unit and the keyer unit each
have their own firmware and each must be updated separately if required. The keyer unit update can
be initiated using either the front panel or the terminal program method. As the router unit has no front
panel it can only be initiated using the terminal program method.
The following equipment is required in order to update the Firmware:
•
PC with available communications port. The communication speed is 57600 baud, therefore a 486
PC or better with a 16550 UART based communications port is recommended.
•
"Straight-thru" serial extension cable (DB9 female to DB9 male).
•
Terminal program that is capable of Xmodem file transfer protocol. (such as HyperTerminal)
•
New firmware supplied by Evertz.
After upgrading the HD9626DSK with new firmware, all presets should be recalled
using the Recall Preset menu item, the values for new features must be set, and the
preset must be saved again using the Store Preset menu item.
IF THIS IS NOT DONE, OLD PRESETS COULD BE RECALLED WITH UNDESIRABLE
SETTINGS.
Terminal Program Setup
5.2.2.
1. If updating the keyer unit firmware, connect the serial cable to the UPGRADE RS232 DB9
connector on the keyer unit rear panel. If you are updating the router unit firmware, connect the
serial cable to the REMOTE CTL DB9 connector on the router unit rear panel.
2. Connect the 9 pin connector on the end of the serial update cable to the PCs' RS-232
communications port
3. Start the terminal program.
4. Configure the port settings of the terminal program as follows:
5. Power up the unit.
Initiating Firmware Upgrade Mode Via the Front Panel (Keyer units only)
5.2.3.
This is the recommended method of updating the software in the keyer units. It is activated through the
GENERAL Setup menu branch. If unable to invoke the upload mode via the front panel as outlined in
step 6 then follow the steps in section 5.2.4.
