3.1 Recommended Practice Before Installation
Before installing a new system, it is preferable to bench test the complete system as configuration problems are easier to
recognize when the system units are close together.
Following installation, poor communications can be caused by:
Incorrectly installed antennas.
Radio interference.
Obstructions in the radio path.
Radio path too long.
If the radio path is a problem, higher performance antennas may help.
Please set up a bench test and familiarize yourself with a pair or set of these modules before taking them out into the field for
installation. For testing analog and digital I/O see section 9.1”Testing Digital and Analog I/O”.
3.2 Zlinx Wireless I/O Modules
Zlinx Wireless I/O encompasses a growing family of products including Base Modules, Expansion Modules, Configuration
Boxes, configuration software and accessories. All modules are built into similar enclosures featuring male local bus plugs
and female local bus receptacles on the sides, which allow modules to connect together (except Base Modules which do not
have left-side connector and Configuration Boxes which do not have right-side connectors). Modules are DIN rail mountable
and feature removable screw terminal blocks.
Zlinx Wireless I/O modules are configured using a Configuration Box, connected to a PC and running Zlinx Manager Software.
Zlinx Wireless I/O systems can operate in Modbus or Peer-to-Peer modes. In Modbus mode a Zlinx Wireless I/O system
exchanges Modbus messages with a Modbus radio modem. In Peer-to-Peer mode two Zlinx Wireless I/O systems provide
wire-replacement functionality. Some Base Modules can also be used as repeaters, to extend the communication distance of
a system.
NOTE: Refer to section 2.2 “Zlinx Wireless I/O Modes of Operation” for more
information.
