The EM-483 is designed for data exchange over Ethernet 10BASE-T and 100BASE-T networks with equipment equipped with an RS-485 interface, forming a MODBUS network.

The EM-483 functions as a MODBUS server for MODBUS client connections over the Ethernet network. It redirects MODBUS requests from clients to devices in the MODBUS network and returns responses from the devices to the clients.

The EM-483 features:

• Flexible addressing in the Ethernet network (MAC address reassignment, static or dynamic IP address).
• Access protection via Ethernet (configuration mode password, IP address filtering for configuration or MODBUS network connection).
• Various exchange modes in the MODBUS network (RTU or ASCII, parity check options: even, odd, or none, wide range of transmission speeds, configurable delay).

Key features of the EM-483:

• Reading parameters of connected devices.
• Sending programmable SMS and email notifications.
• Parameter history in graphs.
• Real-time monitoring.
• Remote device control.
• Internet access via Ethernet.
• Connection of up to 247 Modbus devices simultaneously.
• Galvanically isolated RS-485 interface.

For the device to work correctly, you need to download the latest firmware update (Firmware on EM-483)
