Remote Wakeup Jumper
The remote wakeup jumper enables any firmware running on the VNC2 to support Suspend Monitor
(SUM) mode, allowing the device to reduce power consumption when idle. The VNC2 device can be
configured to wakeup when any data arrives on the receive data (RXD) pin, by connecting the RXD pin
to ring indicator (RI#) input via jumper JP3. When RI# pin is driven low, VNC2 will resume from the
SUM mode immediately. The remote wakeup feature is only available when using the UART interface
on the VNC2. The feature can be enabled when a jumper is present on jumper JP3.
