If you have multiple Trackman iO you must make sure that they are all set to their own unique frequency, 1-25.
- Go to ‘Settings’ -> ‘Advanced Settings’ in TPS
- Select the ‘About’ tab
- Click the “Show Device Web Interface” link, this will open up a browser page showing the status page of iO
- Select the ‘Login’ tab, there is no password. Just hit ‘login’, then ‘force’, and then ‘ok’
- Go to ‘Setup’ Then ‘Frequency Groups’. Here is where you can select the 1-25. Each iO must be on its own unique number. (TM4 frequencies do not overlap with iO)
