Addressing/terminating
IQAN-MC2 use of an ID-Tag
In IQANdesign 3.0 and higher software, more than one IQAN master module can be
used together in a multi-master system. The master modules are each given a unique
address by using an ID-Tag. The value of the ID-Tag identifies the master and will
enable a single project application to be loaded into more than one master module over
the CAN bus. The functionality needed for each master is loaded based on the ID-tag
address. By default, if no ID-tag is installed, the MC2 will be address 0.
Identification of an IQAN-MC2 by address
For normal operation of an IQAN-MC2 in a single master system, the ID-Tag is not
used. It is only needed when the IQAN-MC2 is used in a multi-master system, and an
address other than ’0’ is needed. The connection of an ID-Tag between ADDR-H and
ADDR-L will assign an address to the IQAN-MC2 master module. The desired
functionality based on address is built into the project file using IQANdesign software.
For more information, please refer to the IQANdesign user manual.
It is the combination of address and type that gives each master module a unique
identification. The maximum number of MC2 addresses is 8, denoted as addresses 0, 1,
2, 3, 4, 5, 6, 7 respectively.
In order to assign any IQAN-MC2 a unique address other than ’0’, an ID-Tag will have
to be connected to the positions ADDR-H and ADDR-L.

Terminating
To eliminate interference in the communications through the CAN bus, the CAN bus
must be terminated. By default, the MC2 is terminated internally on all of its CAN
buses. When an IQANdesign application is loaded, it can set individual buses to be
non-terminated.
To give an IQAN-MC2 a unique address, you may use an addressing ID-tag, or an ID-
tag having a combined address and terminating function. The ’T’ values of ID-tags are
ignored, i.e. an ID-tag 3T is equivalent to ID-tag 3.
If the module is located at the end of the CAN-bus, then leave the bus default
terminated in the MC2.
NOTICE
The CAN-bus should not be terminated at the MC2 using an external regular
terminating resistor, due to the fact that terminating is made from within the MC2
module by default.
