Modbus RTU/TCP Gateway for interfacing with ITALSOUND NUM and ALPHA_NUM panels

With the Modbus Gateway for ITALSOUND panels, it is possible to write to ITALSOUND panels using the MODBUS RTU or MODBUS TCP protocol; up to 20 characters per panel and up to 10 panels addressable from 0 to 99 (in the case of multi-line displays, each line counts as a panel with an assigned address).

**Connections**

The gateway features:

- 1 x RS485 serial port for Modbus RTU connection
- 1 x RS485 serial port for communication with ITALSOUND panels
- 1 x Ethernet port for Modbus TCP connection
- 1 screw connector for 24 VDC power supply (min. 3 W)

**Viewing from APP and Modbus RTU / TCP**

The CloudHMI APP allows access to the gateway's graphical interface for configuring communication parameters with the panels. To connect to the gateway, it is necessary to connect it to the Ethernet network using the RJ45 port labeled ETHERNET 1. The ETHERNET 2 port is used for service only.
 To change the Ethernet interface address, simply type the address (default: 192.168.212.1) into a web browser; in case of connection failure, ensure your network card has an address on the 192.168.212.X subnet.
