2430GDAC G-Link D to A Converter
When in automatic resolution detection mode, the 2430GDAC-WARP determines the resolution and
refresh rate of the incoming G-Link video, and automatically configures its video output to match.
When in manual resolution mode, the output video resolution and refresh rate of the 2430GDAC-WARP
is manually configured using DIP switches 3 and 4. Table 5-4 lists the available video resolutions and
their corresponding DIP switch settings.
For proper display of incoming video when in manual resolution mode, the output
video resolution setting must correspond to video being output by the G-Link video
source.

UPGRADING THE FIRMWARE
The 2430GDAC-WARP module contains firmware that is contained in a FLASH EPROM device. From
time to time firmware updates will be provided to add additional features to the unit. The 2430GDAC-
WARP module is fitted with a COM port connector that can be connected to a PC with a straight
through cable. The following procedure will allow you to upload new firmware from your computer.

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.
