Adjustments and Controls
The only user hardware control on the board is the ability to select input buffering of the reference oscillator U4 or an
external source. This is described in section 7.1.3. All other control is via C-BUS and the GUI described in the next section.

Script/GUI Control
To investigate the performance and features of the EV9790 in more detail, a Windows GUI can be used to control the
CMX979 via a PE0003 controller – either by manual register accesses or by running scripts. The GUI is common to the
EV9750 Evaluation Kit, so is referred to as ES9750, and can be found in ‘ES9750xx.zip’.
Setting-Up
Copy the file ‘ES9750xx.zip’, which is downloaded from the CML website following registration, to the hard drive of
your host PC.
Extract the files to the hard drive of your host PC.
Connect a dc supply to the PE0003 Universal Interface Card and set supply voltage level to 5V / 500mA current limit.
Connect a dc supply to the EV9790 and set the voltage level to 6V / 250mA current limit.
Attach a USB cable between the PE0003 Universal Interface Card and the USB port of the PC.
Turn on the power supplies.
Install the USB driver when requested. The driver is in the same folder as the ’ES9750xx.zip’ files were extracted to
(..\Driver). Follow instructions on the screen to install the USB driver. Select the ‘Install this driver software anyway’
option when the Message Box below is displayed:
