Parity parameter is not valid.
Data bits parameter is not valid.

Correct any invalid data in the configuration for proper module operation. When
the configuration contains a valid parameter set, all the bits in the configuration
words will be clear. This does not indicate that the configuration is valid for the
user application. Make sure each parameter is set correctly for the specific
application.
Note: If the APP, BP ACT and OK LEDs blink at a rate of every one-second, this indicates a
serious problem with the module. Call ProSoft Technology Support to arrange for repairs.
