INTRODUCTION Network Module MB-GATEWAY is used to connect EXHAUSTO air handling units to the computer network (Ethernet). Module functions: • TCP/IP Modbus gateway • IPV4 protocol • WEB server • FTP server • Building of Modbus commands using HTTP requests •...
If you are going to use some MB-GATEWAYs in the same LAN, you need to change their IP addresses. LAN cannot have more than one unit using the same IP address, thus for configuring of the MB-GATEWAY you need to connect it directly to the PC.
When the update is finished, the file FIRMWARE.BIN is automatically deleted. Indications of the RJ45 connector LEDs: • Both LED indicators flashes slowly and synchronously – MB-GATEWAY has no firmware installed. • LED indicators flashes slowly in an alternating way – the firmware is being updated.
