CIM-LINK Setup Guide
CAN 2 Termination
Jumpers – Group ACU
Mode
If the CIM-LINK is first or last
module on CAN Bus 2, set
termination jumpers ON J7 &
J8.
CAN 2 Termination
Jumpers –Single ACU Mode
When CIM-LINK is set for Single
ACU Mode, leave CAN Bus 2
termination jumpers OFF J7 &
J8.
No filtering, all messages pass
Filter global I/O messages with
a destination ACU S/N of 0000.
S/N 0000 is for all ACUs
Filter global I/O with a specific
ACU S/N and ACU S/N of 0000.
Filter global time zone
messages.
Filter global anti-pass back
messages.
Filter global I/O messages with
a specific ACU S/N or ACU S/N
of 0000 and filter global time
zone messages.
Filter global time zone and
global anti-pass back messages.
Filter global I/O messages with
ACU S/N of 0000, as well as
global time zone and global
anti-pass back messages.
Sets the CIM-LINK module to
programming mode when
NETCOMP plugged into SCKT1.
Note on Global Message Filtering
Jumpers J9 – J10 – J11 shorted in various combinations on the CIM-LINK module filter
global messages as outlined in the table. Note the following global message filtering
conventions:
Filter messages in both directions – short the designated jumpers on the CIM-LINK
modules on the master and subordinate communication loops
Filter messages in one direction – short the designated jumpers on the CIM-LINK
module where the message originates
Example of Global Message Filtering
As an example, to block global time zone message transmissions from a subordinate
communication loop to a master communication loop but allow global time zone message
transmissions from the global master communication loop to the subordinate
communication loop, jumper J10 would be shorted on the CIM-LINK module located on the
subordinate communication loop.
Global message filtering should be used with caution.
