USB communication
Use USB only for configuration, monitoring and troubleshooting. USB is not a reliable communication method
when used in a electrically noisy environments and communication will not always recover after it is lost without
unplugging and replugging the connector, or restarting the controller. Always prefer RS232 communication when
interfacing to a computer.
Status LED Flashing Patterns
After the controller is powered on, the Power LED will tun on, indicating that the controller is On. The Status LED
will be flashing at a 2 seconds interval. The flashing pattern provides operating or exception status information.
Additional status information may be obtained by monitoring the controller with the PC utility.
Electrical Specifications
Absolute Maximum Values
The values in the table below should never be exceeded. Permanent damage to the controller may result.
