e. Re-connect power to the Base Module.
NOTE: It is necessary to perform Power Cycle on all modules after Firmware
Update.
5.3 Diagnostics and Testing
Most problems are related to incorrect configuration, or radio path problems. Before performing final installation of the Zlinx
Wireless I/O modules, bench test the functionality first. If it does not work properly in this test, it will not work properly
installed. If problems are found, check wiring and software configurations.
If the bench-test is successful, and problems are experienced after installation, check the radio path.
5.3.1 Testing Modbus Mode Operation
Using a Modbus radio modem, a PC and Modbus simulation software (e.g. Modscan) you can test the link and hardware, and
investigate the operation of the Zlinx Wireless I/O. Modscan is a Windows application that simulates a Modbus Master node.
You can read from and write to memory locations on the Zlinx Wireless I/O. Modscan is available as a fully functional time-
limited demo from

5.3.2 Testing Peer-to-Peer Mode Operation
To diagnose possible problems in Peer-to-Peer mode perform the following checks:
1. You must define one of the two Peer-to-Peer base devices as a MASTER and the other as a SLAVE.
2. You must have an equal number of Expansion Modules attached to the Master and Slave units.
3. You must define a "Polling" rate on the Master device. Typically a setting of "0" or "1" seconds works best.
NOTE: “0” causes the firmware to transfer data as fast as possible.
4. For Generation II devices, you must define a Slave "Communications Failure Timeout". Typically a setting of "20" seconds
works best.
5. Both units must have the same Peer–to-Peer Address.
6. Both units must have the same Wireless setting for: "Channel", and "Network Identifier".
Test communications between the units by performing the following tests.
1. Confirm the RF Data LED’s on the Master and Slave devices are flashing, indicating communications between the Master
and Slave devices.
2. If the RF Data and Bus LED's are flashing in a "Rail-Road" manner, the system is NOT communicating.
3. On the Master system connect an LED to DO-1 of the Base Module. The LED should immediately come ON.
4. On the Slave system connect a wire from ground to DI-1 of the Base Module. The LED of the Master device should shut
OFF.
