Card Software Versions and this Manual

When applicable, Ross Video provides for continual openGear product enhancements through 
software updates. As such, functions described in this manual may pertain specifically to cards 
loaded with a particular software build. If you received your LDP-8242 card and this manual at 
the same time, this manual reflects all facets of your card. 

The software version of your card can be checked by viewing the 

Info

 submenu on the card-edge 

display, or by checking the 

Card Info

 menu in DashBoard™. Refer to the section “

Checking 

Card Information

” on page 3-8 for more information. This section provides guidance when 

your card software does not match this manual.

Card software is an earlier version

Card is not loaded with the latest software. Not all functions and/or specified performance 
described in this manual may be available.

You can update your card by:

1.

Contacting Ross Technical Support.

2.

Downloading the latest firmware and/or software for your card onto your computer.

3.

Uploading the new firmware and/or software to your card through DashBoard™.

Card software is a newer version

A new manual is expediently released whenever a card’s software is updated and specifications 
and/or functionality have changed as compared to an earlier version (a new manual is not 
necessarily released if specifications and/or functionality have not changed). A manual earlier 
than a card’s software version may not completely or accurately describe all functions available 
for your card.

If your card shows features not described in this manual, you can check for the latest manual (if 
applicable) and download it by going to our website.
