3.1.1.1: Technique for Close Positioning of
Transmitters

July 2012
Wireless Dual Analog Input Interface Transmitter
Transmitters may be placed closely together by carefully following this
procedure. If this procedure for close positioning of Transmitters is not
followed, the communication range of the Transmitters will be
significantly reduced and the Transmitters may eventually lose
communication with the Base Radio entirely. This procedure is easy to
implement, but please read carefully for a full understanding.
The Base Radio synchronizes with the Transmitters in Synch Groups of 7,
organized by their RF ID numbers. If you want to place two Transmitters
closer than 6 feet, make sure that you have set them in different groups.
Note that this only applies to Transmitters that are communicating with the
same Base Radio. The groups are defined in the following table:
Group

2
3
4

8

For example, if two Transmitters are placed one foot apart and the first
Transmitter has an RF ID number of 027, that means it is in the 4th group
(22-28). The second Transmitter must have an RF ID number that is in
another group (less than 22 or greater than 28). Setting the RF IDs of two
closely spaced Transmitters so that the RF ID numbers are greater than 7
apart ensures that the Transmitters are in different Base Radio sync
groups. This allows the closely spaced Transmitters to properly receive
their synchronization signal from the Base Radio and maintain their proper
communication and range.
You can also ensure that closely spaced Transmitters maintain their
synchronization with their Base Radio by simply assigning each of the two
closely spaced Transmitters to talk to a different Base Radio.
Either way, following this process will keep the Base Radio and
Transmitters properly synchronized for long-term communication.
