Thank you for purchasing a Zlinx Wireless I/O product! This product has been manufactured to the highest standards of
quality and performance to ensure your complete satisfaction.
2.1 Zlinx Wireless I/O Product Family
Zlinx Wireless I/O modules provide easy-to-use, cost-effective Peer-to-Peer or Modbus wire-replacement solutions.

The Zlinx Wireless I/O family of products features a selection of operational modes, communications ranges and I/O
combinations. The system is scalable making it easy to start with a few I/O points and build a system with the required I/O
mix.
2.2 Zlinx Wireless I/O Modes of Operation
Zlinx Wireless I/O systems can operate in Peer-to-Peer or Modbus modes. Some Base Modules can be configured as
repeaters to extend the radio coverage distance.
2.2.1 Peer-to-Peer Mode
In Peer-to-Peer mode two Zlinx Wireless I/O systems provide wire replacement functionality. In this mode one Base is
configured as the Peer-to-Peer Master and the other as the Peer-to-Peer Slave. It does not matter which end of the link is the
Master and which is the Slave. Both Base Modules must be the same model. Analog and Digital Input signals connected to
AI’s and DI’s on one module appear on the corresponding AO’s and DO’s on the other module and vice versa. Any Expansion
Modules included in a Peer-to-Peer system must be chosen to be complimentary. For example, if Expansion Module 1 on one
end of the link on System-1 is a ZZ-4AI (4 Analog Inputs), Expansion Module 1 on the other end of the link on System-2 must
be a ZZ-4AO (4 Analog Outputs). Note: Changing the the OTA data rate to 9600 on the LR model will slow the data
throughput. The approximate polling rate is one second.
