Figure 4. VAM control interface
The VAM control interface is marked with a blue dashed line in
Figure 3
above.
Figure 4
shows the
VAM Control and ID interface and pin header connector.
VAM Control and ID interface includes the following baseband interfaces; for more detail, see VAM-
CM interfaces on page 11.
> System USB
> Direct USB interface to access VAM-CM for direct controls and firmware updates. This
interface can also be used as VAM control interface if selected by VAM Boot selection.
> USIM interface
> Interface for external USIM socket located in VAM terminal.
> VAM control UART
> UART interface to control VAM-CM functions. UART is the default interface for VAM
control. USB control mode can be selected by VAM Boot selection.
