Applications
• Industrial devices (PLCs, drives, motor controls, process analyzers) • OPC server applications
• PC controllers (Think and Do, Steeplechase)
Modbus Problem #1
Ethernet Master Serial Slaves
MESR9xx modules can be used to integrate serial slave devices
on a MODBUS TCP network. This allows TCP Masters to
control serial slave devices.

• Auto detecting Ethernet 10/100Base-T copper and fiber
optic connections
• Operating temp: -34 to 74°C (storage: -40 to 80°C)
• 10-48 VDC operation
• Management: Multiple TCP/IP client sessions
Vlinx Modbus Gateways bridge devices on Modbus serial networks (RS-232, RS-422 or RS-485) with those on Modbus TCP
networks, allowing seamless integration of any Modbus device. Each serial port is accessible over a LAN or WAN by up to 16
simultaneous Modbus TCP masters. MESR series Modbus Gateways boast an extensive line-up of Ethernet port configurations –
from standard RJ-45 copper to almost any fiber optic option. Versions are available with an additional Ethernet port that functions
like an Ethernet switch, allowing pass-through connectivity for other Ethernet devices. The port can be used to “daisy chain”
multiple gateways.
Take Advantage of Fiber Optic Options from B&B Electronics!
MODBUS
WIDE TEMP
Vlinx Serial Servers have the largest selection of standard fiber optic port options available. If your Ethernet network is using
single-mode or multi-mode fiber optics, our serial servers are the natural choice for serial device connectivity. Fiber Optics
offers the following benefits:
• Immune to Noise, EMI, RFI
• No Cross Talk
• Signal Security
• Lower Bit Error Rate
Fiber Optics is especially advantageous for long distance communications. The standard CAT 5 network is limited to about 100
meters. With fiber optics you can extend that range. B&B Electronics Vlinx Serial Servers have options for multi-mode and
single-mode fiber. Multi-mode fiber extends the range to 2.5 miles (4 km). Single-mode fiber extends the distance to 9 miles or
15 km. We even have 40 and 80 km options available. Call for details!
Modbus Problem #2
Serial & Ethernet Masters, Serial & Ethernet Slaves
MESR9xx modules can also integrate multiple master
devices onto serial and Ethernet networks.
