IO614 Pin Mapping
IO614 Pin Mapping — Reference information about
the I/O module connector
Description
The IO614 I/O module offers four DB9 connectors. Each connector contains a CAN
channel.
Additionally, there is one LIN channel on the CAN channel 2 connector.
Channel Location
The following figure shows the outlines of an example Baseline target machine
with the IO614 I/O module located in the top-right corner.

Note that the four DB9 connectors are labeled A, B, C & D. Connector A contains CAN channel 2 Connector B contains CAN channel 1 Connector C contains CAN channel 4 Connector D contains CAN channel 3

Connector Pin Mapping
The following figure shows the pin numbering of a DB9 connector when looking from
the front (outside of the target machine).
The pin mapping of the four connectors is identical and is listed in the
following table:
For proper operation, a CAN topology requires electrical termination in the form
of resistors.
The IO614 I/O module does not include termination resistors. The full resistor
comes with the CAN module loopback cable provided by Speedgoat.
Raw Module
In rare cases, when the IO614 I/O module is used on a different target machine
than the Baseline, the channels can be placed individually using boxed-header-to-DB9
adapter cables.
The channels on the module are ordered as shown in the following picture:
CAN LS Switch
The adapter provided routes the CAN LS signals to the same pins as CAN HS/FD. This
means that the same cables can be used for CAN HS/FD and CAN LS operation. The CAN
LS switch can be provided on request.
