EM-486 is designed to collect data from connected devices (analog sensors and MODBUS devices), transmit data to a server, provide data access (via MODBUS TCP protocol or SMS messages), and track events with automated responses (relay control, SMS alerts, writing values to MODBUS devices, and data logging).

Key Features of EM-486:

Flexible Connectivity Options:

• Wired or wireless communication.
• Automatic selection of the server connection method.
• Automatic or manual detection of GSM provider and communication parameters.
• Customizable MAC address and Ethernet settings.

Access Protection & Security:

• Password protection for configuration and MODBUS network access.
• Connection restricted to a predefined server with automatic authorization.
• SMS-based control password.

Multiple RS-485 Communication Modes:

• Supports RTU and ASCII formats.
• Configurable parity check (even, odd, or none).
• Wide range of transmission speeds.
• Adjustable communication delay.

Advanced Data Acquisition & Event Programming:

• Configurable data collection, event monitoring, and event-based actions.
• Programmable outputs for event-triggered actions and alarms.
• Configurable analog sensor inputs.
• Programmable pulse counters for each sensor.
• Power output for connected sensors.
• Backup power input.

Service Functions:

• Real-time clock (RTC).
• Firmware update capability.
