CHAPTER 1: ABOUT YOUR MES1A/B CONVERTER

Thank you for purchasing an MES1A or MES1B Modbus TCP to Modbus ASCII/RTU

Converter! Like all B&B Electronics products, this product has been manufactured to

the highest standards of quality and performance to ensure your complete

satisfaction.

MES1A and MES1B Modbus TCP to Modbus ASCII/RTU Converters are easy-to-use,

cost-effective solutions for connecting new and existing Modbus ASCII/RTU serial

devices to TCP/IP networks. The MES1A provides this connection for Modbus devices

with RS-232 interfaces; the MES1B facilitates Modbus devices with RS-422 four-wire

point-to-point interfaces, or RS-485 four or two-wire multi-drop bus connections.

MES1A and MES1B Converters

MES1A Converters allow new and legacy Modbus ASCII/RTU slave devices with RS-

232 serial ports to operate on a TCP/IP network as full Modbus TCP slaves. All

Modbus TCP devices on the network can share access to the Modbus ASCII/RTU

device.

MES1B Converters allow Modbus/RTU slave devices with RS-422/485 interfaces to

operate on a TCP/IP network as full Modbus TCP slaves. All Modbus devices on an

RS-485 bus can be connected to the TCP/IP network via the MES1B, allowing them all

to be accessed by Modbus TCP/IP devices on the network.

Traditional Modbus ASCII/RTU master devices also can be connected to TCP/IP

networks using the MES1A/B, making the device appear to be a full Modbus TCP

master on the network. It can directly access Modbus TCP slave devices. It also can

access other Modbus ASCII/RTU slaves that are connected to the network via other

MES1A/B Converters, as if it is talking directly to a Modbus ASCII/RTU slave.

FEATURES

Converts Modus ASCII/RTU to Modbus/TCP

Small, economical and configurable

MES1A supports TD, RD and GND RS-232 lines

MES1B supports TDA(-), TDB(+), RDA(-), RDB(+) RS-422/485 lines

LEDs on network connection indicate link integrity and data transfer

activity

10/100 Mbps auto-detecting operation

Removable screw terminal strips for power supply

Removable screw terminal strips for RS-422/485 connection (MES1B)

Device Installer user interface software included

DIN rail mountable
