connect the dock to the AC/DC adapter. This cable is included in the AC kit for off-
vehicle use.
COM1 and COM2 Connector
VMXD Enhanced Dock only: Because the power supply connector port for the
VMXD Enhanced Dock contains COM1 RTS and CTS signals, the COM1 port on the
dock should not be sued when the power cable is used for screen blanking to avoid
port conflicts.
