Factory Reset
This should be done only when absolutely necessary. To reset the module, follow these steps in order:
1. Power-down the module.
2. Install the C And BR jumpers.
3. Power-up the module.
4. Module will Reset the USART to 57.6k Baud
5. Module will Reset the RS485 Port to 9600 Baud
6. Power-down the module.
7. Remove the C And BR Jumpers
8. Power-Up the module and use default settings.
Note: If the bus length exceeds more than 5,000 feet, users may experience data corruption. This factory reset
process is true only for the Emulator and Autoencoder Version.
