CAN Initialization Results
1.
Power up the Viper Pro field computer.
2.
The CAN Initialization Results screen displays. If the CAN system found all of the connected nodes, touch
Start Viper . If not, touch Retry CAN Init .
Note:
If the product nodes are not found and this is a new installation, skip to the Re-Addressing Product
Nodes section on page 30 and follow the instructions for addressing the product nodes.
3.
If product nodes which had been ‘Found’ during previous Viper Pro applications, but are still not displayed
after step 2, troubleshoot the CANbus system to determine why the node is not communicating with the
CAN system (i.e. No logic power, ground issues, faulty CAN connection, etc.).
CAN Node Off-line Errors
The most likely causes for losing CAN communication between the field computer and any one of the nodes
are:
1.
Corroded and/or open connections in the circuit.
2.
Field computer and/or CAN node logic power and grounds connected to a “dirty” power source (dirty power
is defined as any circuit with a variable load that exceeds 1 ampere). This is especially true of circuits
loaded by electrical coils.
3.
Field computer and nodes connected to different power and/or ground sources (e.g. battery, alternator or
power bus). This can result in components operating at different voltage planes. Connect the field computer
and nodes to the same power source via separate leads to eliminate potential issues.
4.
Supply voltage below required minimums due to weak alternator or battery outputs. Check the machine
battery and alternator and repair or replace as necessary.
Re-Addressing Product Nodes
The Raven OmniSeed system is compatible with the Raven air cart node and the Raven product controller
nodes. Each of these nodes is capable of providing up to five control channels for the OmniSeed system. Since
the Raven Viper Pro is only capable of controlling five control channels, if both the air cart and product
controller nodes will be connected to the OmniSeed system, each node must be properly configured to ensure
that the nodes control products properly.
Note:
If a Raven air cart and product controller node will be used on an air seeder system, the product
controller node should be disconnected from the CANbus network prior to beginning the following
procedure. The air cart node should be configured independently first to ensure that the proper
channels are available for air cart products.
Configuring the Air Cart Node
The air cart node should be set up for the maximum number of bins capable of being controlled by the
OmniSeed system. If a product controller node will be connected to the CANbus network, control channels on
the air cart node must be disabled before the field computer will detect any control channels available on the
field computer.
It is recommended to disconnect the product controller node from the CANbus network during the initial setup
of the air cart node. Refer to the following procedures to set up the air cart node on the CANbus network.
