CAN Port
Figure 5 and Table 4 describe the CAN port pins and signals.
Figure 5.
CAN Port Pinout
Note
The NI roboRIO contains an internal 120 W termination resistor between
L (GRN) and H (YEL).
DIO <0..15> DGND Input or
Output
General-purpose digital lines with
3.3 V output, 3.3 V/5 V-compatible
input. Refer to the
DIO, PWM, and
Relay Lines section for more
information.
UART.RX DGND Input UART receive input. UART lines are
electrically identical to DIO lines.
UART.TX DGND Output UART transmit output. UART lines are
electrically identical to DIO lines.
DGND — — Reference for digital signals, +5 V,
and +3.3 V.
