2.3 TELEGRAM FILTERING
ZMCoup RF provides two complementary filter types:
Group address filtering : ETS automatically generates a group address table
for the project loaded. This table is transferred to the line coupler during
complete ETS downloads over it.
The Filter Table will determine which group addresses will be routed. A
Group Address will be on the Filter Table when, at least, in both devices, one
on the lines under ZMCoup RF and other in a different line, there is an object
that has such address linked.
Given the previous condition, when a telegram containing a group address in
the
“destination address” field arrives, the line coupler will look up if such
address exists in the group table, and eventually transmit the telegram to the
other side
–if the address is found– or drop (block) it –if it is not–.
The Filter Table can be previewed. By making a right click on ZMCoup RF
and selecting the option “
Preview Filter Table
”:

Note : making further changes to a project (addresses, etc.) requires
downloading the updated filter table to the line coupler .
