Memory
- EEPROM (Erasable Programmable Read-Only Memory): The two EEPROM sockets on the board can accommodate modules with a combined storage capacity that typically ranges from several kilobytes to a few megabytes. This memory is used to store firmware, configuration parameters, and other critical data that the board needs to operate and maintain its functionality over time. The ability to erase and reprogram the EEPROM allows for customization of the board's behavior and adaptation to different industrial processes and changing requirements.
- Random Access Memory (RAM): There is also a certain amount of onboard RAM for temporary data storage during operation. The RAM capacity might range from a few kilobytes to tens of megabytes, depending on the design. It is used by the microprocessor to store and manipulate data such as sensor readings, intermediate calculation results, and communication buffers as it processes information and executes tasks.

This allows for flexible communication with other devices that use the RS-485 protocol, which is often used in industrial environments for long-distance or multi-drop communication scenarios.
- Protocols: It can support various serial communication protocols built on top of RS-485, depending on the application needs. For example, it might be used with Modbus RTU (Remote Terminal Unit) protocol for communication with multiple slave devices in a master-slave configuration, enabling efficient data exchange between different components in a distributed industrial control system.
- Operating Temperature: The DS3800HPLA is designed to operate within a specific temperature range, typically from -20°C to +60°C.
