About MESR424 Modbus Gateways

MESR424 Modbus Gatewaysconnect Modbus networks (RS-232, RS-422 or RS-485)

to Ethernet networks, allowing the Modbus network to become a node on the network.

The serial ports can be accessed over a LAN/WAN using Direct IP Mode connections.

MESR424 Modbus Gatewaysfeature 10BaseT or 100BaseTX copper network media and

fiber optic media options, depending on the model. MESR424 Modbus Gateways are

built for use in industrial environments, featuring an IP30 approved slim line DIN rail

mountable case. They operate from a range of DC power supply voltages and feature

pluggable terminal block power connectors. An external power supply, sold separately, is

required. MESR424 Modbus Gateways have an additional Ethernet port which functions

much like an Ethernet Switch.

MESR424 Modbus Gateway Model Numbering

MESR424 Modbus Gatewaysare a growing family of products. Models are available

with DB9 or Terminal Block connections. Network connection options include

10BaseT/100BaseTX copper or several different fiber optic options.

2. Hardware

MESR424 Modbus Gateways are enclosed in DIN rail mountable enclosures and feature

LED indicators, power, Ethernet and serial connectors and a recessed Mode/Reset switch.

Package Checklist

MESR424 Modbus Gateways are shipped with the following items included:

MESR424 Modbus Gateway Module

Quick Start Guide

CD with User Manual, Quick Start Guide and configuration software.

MESR424 Modbus Gateway Enclosures and Mounting

All MESR424 Modbus Gateway models are built into similar enclosures. Modules are

DIN rail and panel mountable.

2. Hardware

LED Indicators

MESR424 Modbus Gateways have three types of LED indicators: Ethernet Link LEDs,

a Ready LED and Serial Port LEDs.

Figure 3. Port LEDs

E1/E2 Ethernet Link LED

The Ethernet Link LED (E1 or E2) illuminates (green) if the Ethernet is connected.

When the LED is blinking it indicates that there is data traffic on the Ethernet link.

The Ethernet Speed (E1 or E2) LED is OFF if the connection is 10BaseT and ON if the

Ethernet connections is 100BaseT.

E1 is used for all models to connect to the network. E2 is a pass-through Ethernet

connector.

Ready LED

The Ready LED (green) blinks if the system is operating correctly, once per second in

normal operating conditions, or three times per second in reset, configuration mode, or

when loading factory defaults. If the LED is off or steady, it indicates the system is not

operating correctly.

2. Hardware

Serial Port LEDs

MESR424 Modbus Gateways feature multiple serial ports. Each serial port has an

associated LED. Serial Port LEDs blink (green) when data is being transmitted or

received on the serial port.

Figure 4. Serial Port LEDs

Mode/Reset Switch

A recessed momentary Mode/Reset switch is located next to the power ports. To activate

the switch, insert a small plastic tool through the hole in the enclosure and press lightly.

Figure 5. Mode/Reset Switch

The Mode/Reset switch can be used to:

Initiate a Hardware Reset

Enter Console Mode

Reload factory defaults
