The connections of the CAN bus interface are on the 9-pin D-SUB connector;
the pin assignment is shown below.

Power supply
(Low speed only)
The "low speed" version Pro II-CAN-2-LS requires an external power supply of
12V DC. The module needs a power supply for each controller separately.
With low-speed CAN, both DIP switches (see fig. 144) must be set downward
(off-position).
Bus termination
(High speed only)
If the CAN module functions as the physical termination of a high-speed CAN
bus, it must be terminated with a 120
Ω
resistor (only the first or the last CAN
node).
If a termination is necessary, move the DIP switch (see fig. 144) upward. CAN
nodes, which are not positioned in an end-location, must not be terminated.
