Confirm the correct PC port is selected in the configuration software and the PC port is not being used by another application.
Ensure the serial port settings for the SCADAPack controller serial port and the COM settings for the
Radio Module are the same.
Ensure correct power is connected to the PWR IN terminals on the Radio Module.
Ensure the SCADAPack controller is properly powered as described in the controller user manual.
Ensure correct power is connected to the PWR IN terminals on the Radio Module.
Verify that the system has a unique network address. Nearby systems with the same address will cause interference.
If omni directional antennas are used on remote stations, consider changing to directional antennas. This will often limit interference to and from other stations.
Check for secure interface connections at the radio and the connected device.
Check the antenna, feed line and connectors.
Reflected power should be less than 10% of the forward power reading.
If the remote radio is in synchronization, but performance is poor, check the received signal strength using the RSSI command If RSSI is low, it may indicate antenna problems, or misalignment of directional antenna headings.
Verify proper programming of system parameters: mode, network address, data interface baud rate, transmitter power, CTS delay, etc. For store-andforward applications, also verify the following: SAF is ON and extended address is properly programmed at each extension.
The RETRY and REPEAT commands may be increased to deal with interference, or decreased to increase throughput and reduce latency.
Try turning on FEC. FEC on gives some coding gain, but comes at the cost of reduced throughput.
Reduce the REPEAT count.
Make sure HOPTIME is set to 7.
