About Your MES1A/B Converter
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 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

Link LED
When the Link LED located on the Ethernet jack is illuminated it
indicates that a connection (link integrity) has been established
between the converter and the network. Its color is green if
connected to a 100BaseT network; orange if connected to a
10BaseT network. It turns orange briefly during the power up
process.
Activity LED
When the Activity LED located on the Ethernet jack is flashing
(green) it indicates data is being sent across the network. This LED
turns orange briefly during the power up process.

Reset Switch
The Reset switch is accessible on the top edge of the MES1A/B
(same edge as the power supply connector) through a small hole in
the MES1A/B enclosure. It allows you to reset the MES1A/B by
inserting a small tool through the hole and pressing the momentary
switch for about 1 second. The MES1A/B restarts with its last saved
configuration settings.

RS-422/485 Switch (MES1B only)
The RS-422/485 switch allows you to set the MES1B Converter for
RS-422/485 four-wire or RS-485 two-wire operation.
• When the switch is in the left position, the MES1B operates in
RS-422/485 four-wire mode.
• When the switch is in the right position, the MES1B operates
in the RS-485 two-wire mode.
Ethernet Port Connector
The Ethernet Port connector is a standard RJ-45 receptacle that
allows the converter to be connected to an Ethernet network. Two
indicator LEDs (described above) are built into the RJ-45
connector.
DB-9M Serial Port Connector (MES1A only)
The Serial Port Connector on the MES1A is a DB-9 male
connector (configured as a DTE) supporting RS-232 serial
communications including TD (Pin 3), RD (Pin 2) and GND (Pin 5)
signal lines. If the Modbus device you are connecting to the
MES1A is configured as a DCE you will use a straight-through
serial cable. If the Modbus device is configured as a DTE, use a null
modem cable.
Refer to Appendix D for connection pin-outs.
RS-422/485 Connector (MES1B only)
The RS-422/485 connector on the MES1B is a five position
removable terminal block with screw downs. The connector
provides screw connections for:
• Terminal 1 - RDB(+)
• Terminal 2 - RDA(-)
• Terminal 3 - TDB(+)
• Terminal 4 - TDA(-)
• Terminal 5 – Ground

RS-422/485 Four-Wire Mode
When the MES1B is configured to operate in RS-422/485 four-wire
mode (RS-422/485 switch in the left position) its receive terminals
are connected to the transmit terminals of the Modbus device it is
communicating with. Its transmit terminals are connected to the
receive terminals of the Modbus device it is communicating with.

RS-485 Two-Wire Mode
When the MES1B is configured to operate in RS-485 two-wire
mode (RS-422/485 switch in the right position) the two-wire RS-
485 two-wire communications cable pair is connected to Terminals
TDB and TDA. The communications cable ground/shield is
connected to GND.

No jumpers are required to bridge the transmit and receive lines in
two-wire mode.
Power Connector
The Power Connector is a removable two-position screw terminal
block with screw down. The MES1A/B requires between 10 VDC
and 30 VDC (3.6 Watts). Typically a 12 VDC power adapter is
connected to the terminal block via bare wires. The terminal block
can be unplugged to remove the converter from service.

Connecting the Hardware
The MES1A is connected to its Modbus device via a DB-9M
connector and an RS-232 cable. The MES1A is configured as a

straight-through cable. If the connected Modbus device is
configured as a DTE, use a null modem cable.
Always check the interface specifications of the Modbus device to
determine whether it is a DTE or DCE before connecting.
The MES1B is connected to its Modbus device via the RS-422/485
terminal block. In RS-422/485 four-wire mode a cable containing
two pairs and a ground/shield is used. In RS-485 two-wire mode a
cable containing one pair and a ground/shield is used.
Power is supplied to the converter via the power supply terminal
block.
Typically, the MES1A/B is connected to the network via a hub
switch or router using standard straight-through CAT-5 cable. (If
you are connecting the MES1A/B directly to a PC’s network
interface a crossover Ethernet cable is required.)
