POWER SUPPLY
The controller is powered using a 24V external power supply through banana plugs U6, U7.
CONFIGU RATI ON TAB
In the Configuration tab, the USB Instance dropdown list is used to select the desired host if you have
many controllers connected to your PC. The Module Index indicates the module of the selected USB
instance that needs to be configured.
1. The configurations in this tab can be set to all modules or per module.
2. Controller Voltage supply output can be set to 3.3 or 3.5 V. Also, it can be automatically set to the
option that gives the closest value to 3.3 V at the module side. To do so, check Automatic voltage
supply based on module x option and select the reference module to base the calculations on. Note
that this option is enabled only when Apply for all modules is selected.
