22 Envizio Pro™ and Envizio Pro II® Installation and Operation Manual
Chassis Interface Cable and CAN Switch Box Connection
Note:
The CAN Switch Box and switch box mounting bracket should be mounted to the Envizio Pro field
computer prior to beginning the following procedure. Refer to the CAN Switch Box Installation and
Operation Guide for detailed instructions.
1.
Locate the single round connector labeled ‘To Chassis or SmarTrax Tee Cable’ on the Envizio Pro/Viper Pro
chassis interface cable (P/N 115-0172-001).
2.
Insert this connector into the ‘To Cab Cable’ on the chassis cable installed on the vehicle. Thread the
connectors together to secure the connection.
3.
Route the end of the cable with two round connectors to the back of the Envizio Pro and connect to the
main and auxiliary ports.
4.
Connect the 2-pin Deutsch connector labeled ‘Switched Power Output’ to the back of the CAN Switch Box.
5.
Connect the 4-pin Deutsch connector labeled ‘CANbus’ to the back of the CAN Switch Box.
6.
Connect the 3-pin round connector labeled ‘GPS Speed Out’ to the back of the CAN Switch Box.
Note:
Disconnect the 3-pin ‘GPS Speed Out’ connection if using GPS speed over CAN as the speed
source. Refer to the Speed Cal section on page 187 for additional assistance with speed sensor
types and speed calibration values.
If the chassis interface cable (P/N 115-0172-001) is installed and the internal DGPS receiver will
be used for DGPS reception, the ‘Internal GPS Receiver Output’ and ‘GPS Receiver/DGPS’ port
connectors must be connected together.
DGPS Antenna
Note:
To enable the guidance capabilities of the field computer, DGPS signal must be supplied by one of
the following:
•
The internal DGPS receiver
•
An optional external receiver capable of outputting messages at a minimum of 10 Hz.
For more information on configuring the Envizio Pro or Envizio Pro II field computers for one of the
above options, see Chapter 7, Tools Menu.
With the internal receiver, the Envizio Pro or Envizio Pro II only requires a connection to a DGPS antenna in
order to create application maps. To ensure the best possible signal reception, the following recommendations
should be considered when selecting the DGPS antenna mounting position.
•
Mount the DGPS antenna to the tallest point of the vehicle (usually the vehicle’s cab) using the standard
magnet mount.
•
Make sure that the DGPS antenna has a clear 360° view of the sky.
•
Mount the DGPS antenna at least of 36” [92 cm] from other antennas (e.g. radio, cellular, etc.) to avoid
signal interference.
•
The simplest setup is achieved by mounting the antenna on the center-line of the vehicle.
