CAN option
Joysticks CAN J1939 protocol option, designated as model code CAN, broadcasts two J1939 messages to
communicate device information: Basic Joystick Message 1 (BJM1) and Extended Joystick Message 1
(EJM1). The two CAN options available are:
•
CAN 2.0B, J1939 protocol option
•
CAN 2.0B, CANopen protocol option
CAN+ option
Joysticks with the CAN+ option, designated as model code CPL, allow eleven external inputs that are not
associated with the joystick shaft position or grip functions to be read by the joystick’s microcontroller
and broadcast by the joystick’s CAN transceiver.
CAN+ joysticks broadcast four CAN messages. Basic Joystick Message 1 and Extended Joystick Message 1
have the same data content as the CAN option, above. External digital input (DIN) and analog input (AIN)
input information is contained in Basic Joystick Message 3 and Extended Joystick Message 3. The data
field format for Basic Joystick Message 3 and Extended Joystick Message 3 is the same as that for Basic
Joystick Message 1 and Extended Joystick Message 1.
CAN+ external inputs
Analog inputs (AIN)
•
All external analog inputs must be powered by the JS6000 joystick 5 Vdc regulated power supply
(connector pin 8).
•
No calibration, error checking or software filtering is performed on analog data received from
external inputs.
•
External analog data is scaled in raw form from 0 to 1000 counts.
•
Data associated with CAN+ pins 9, 10,11 and 12 is broadcast in both Basic Joystick Message 3 and
Extended Joystick Message 3. For analog inputs use the appropriate data bytes in Basic Joystick
Message 3 or Extended Joystick Message 3.
Digital inputs (DIN)
•
External inputs are pull-down and must be powered by a voltage source <32 Vdc. Low state is
interpreted as <0.97 Vdc. High state is interpreted as >4.00 Vdc.
•
Data associated with CAN+ pins 9, 10, 11, 12 is broadcast in both BJM3 and EJM3. For digital inputs
use the appropriate data bytes in BJM3.
