If HeadStart is unable to communicate with the Power Patrol meter, the
Status
box displays the
following message: “Unable to establish connection with meter, please check settings and try again”
Try the following to resolve the communication error on a serial Power Patrol:
No RS-485 option available in the PC COM Port drop-down list—indicates the Power Patrol is not
properly connected or the required software driver is not installed.
Modbus Base Address Switch does not match the selected hex switch settings on the Power
Patrol—change the switch settings.
The selected Baud Rate does not match the Power Patrol baud rate—change the baud rate.
