C.3.1 Making a Permanent Connection to the
Automotive EN-2000
The automotive EN-2000 uses a permanent power connection to your
automobile’s battery.
Note:
Encore Networks, Inc., provides the connectors for the automotive
EN-2000’s RS485 serial port and its DC power input port. The customer will need
to build the cables for those connections.
