UPGRADING THE 2430DAC-HD FIRMWARE
The 2430DAC-HD module is fitted with a COM port connector that can be connected to a PC with a
straight through cable.
6.1. REQUIREMENTS
You will need the following equipment in order to update the 2430DAC-HD 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) or (DB25 female to DB9 male)
•
Terminal program that is capable of Xmodem file transfer protocol (such as HyperTerminal)
•
New firmware supplied by Evertz.
