Barrow Mods 1-Port Modbus Gateway MGate MB3180/MB3280/MB3480 Series 2 in 1 accessory
Converts Modbus TCP to serial with one Ethernet port and up to four RS-232/422/485 ports supporting 16 masters and 32 requests each
- Converts Modbus TCP to RTU/ASCII protocols
- 16 TCP masters handle 32 requests each
- 1 Ethernet and up to 4 serial ports
- Auto Device Routing simplifies setup
- Route by TCP port or IP address
Industrial Protocol Gateway
The Barrow Mods MGate MB3180/MB3280/MB3480 series is a 1-port Modbus gateway that converts between Modbus TCP and Modbus RTU or ASCII protocols. It features one Ethernet port alongside one, two or four RS-232/422/485 serial interfaces for connecting legacy field devices to modern networks. The unit supports up to 16 simultaneous TCP masters with up to 32 simultaneous requests per master. Auto Device Routing and flexible routing by TCP port or IP address simplify deployment.
Integration Fit
This gateway suits system integrators and automation engineers who need to bridge Modbus TCP networks with serial Modbus equipment in industrial environments. Buyers requiring multiple independent Ethernet uplinks or support for non-Modbus industrial protocols such as PROFINET or EtherNet/IP should look at other product lines. The single Ethernet port design also limits its use in redundant network topologies that demand dual LAN interfaces.
Deciding Specification
The defining specification is the single Ethernet port combined with a choice of one, two or four RS-232/422/485 ports in the same unit. This port count determines how many serial devices or buses can be connected directly without adding external serial expanders. Select the 3180, 3280 or 3480 model variant to match the exact number of serial ports your installation requires.

Questions about this item
How many simultaneous TCP masters can the MGate MB3180/3280/3480 handle, and what is the request limit per master?
The gateway supports 16 simultaneous TCP masters, each capable of up to 32 simultaneous requests.
What physical serial ports does the 1-port MGate model provide for mounting and connection?
It provides one RS-232/422/485 serial port alongside a single Ethernet port for integration.
How is the Modbus gateway installed, and which configuration step is most often missed?
Connect power, Ethernet, and the serial device, then use the web console to enable Auto Device Routing by TCP port or IP address — skipping this routing setup is the common oversight.
