RS232 Connection
using an External
Power Brick
A special dongle cable is used, where one end of the cable plugs into the VX 820
while the other end terminates in a DB-9 connector housing. On the housing, a
DC jack is provided to connect to an external power brick. This is a generic cable
for all RS232-based hosts.

option, the host end has a molded housing which exposes the standard USB plug.
