To configure the MOD-1AO module for communication over a Modbus network, you can use the Modbus Configurator software provided. Here are the steps to configure the communication settings and the default parameters:



1. **Accessing Communication Registers:**

   - The communication registers can be accessed via the Modbus Configurator software using a USB connection to the module.



2. **Default Communication Settings:**

   - **Address:** 1

   - **Baud Rate:** 19200

   - **Parity:** No

   - **Data Bits:** 8

   - **Stop Bits:** 1

   - **Reply Delay [ms]:** 0

   - **Modbus Type:** RTU



3. **Configuration Registers:**

   - The configuration registers allow you to set and modify various communication parameters such as address, baud rate, parity, etc.



4. **Watchdog Function:**

   - The watchdog function is a safety feature that resets the module if no valid message is received within a specified time. The default value is 0 milliseconds, which means the watchdog function is disabled.



5. **Indicators:**

   - The LEDs on the module indicate different statuses such as power, communication activity, output voltage, and output current.



6. **Using Modbus Configurator:**

   - The Modbus Configurator software is a universal program that allows you to configure all available modules, including the MOD-1AO. It enables you to set communication parameters, read/write registers, and observe real-time changes.



By following these steps and utilizing the Modbus Configurator software, you can easily configure the MOD-1AO module for communication over a Modbus network with the specified default settings.
