The firmware of the CD24 can be updated remotely over its output port.
In Scream!’s main window, right-click on the instrument's icon and select Terminal... from the pop-up menu. (If this fails, connect the instrument directly to a serial port and right-click on the serial port instead.)
Check that there is two-way communication with the digitizer by pressing Enter. The instrument should reply with ok on a new line.
Type ok-1 to enable advanced commands. The instrument will reply with a message describing the current firmware version.
If the firmware needs updating:
Type load and press ENTER. The instrument will display
load C
The instrument will now wait up to 10 seconds for you to provide a firmware file.
Right-click on the terminal window and select Send file...:

Depending on the speed of the link, it may take up to 20 minutes to transfer the firmware.
When the transfer completes, type re-boot to restart the CD24.
At this point you may want to switch the CD24 off and then back on, to ensure that it restarts properly.
Allow 30 seconds for the instrument to restart.
Right-click on the instrument's icon in Scream! and select Configure... Check that the Software Version corresponds to the version you have just uploaded.
