1 Overview
The W5-JEM1 is a single-channel EtherNet/IP to Serial Device Gateway that provides a flexible EtherNet/IP interface to one or more ASCII or Modbus devices. This permits it to interface with a wide variety of TIA/EIA­232 (RS-232), TIA/EIA-422 (RS-422), and TIA/EIA-485 (RS-485) devices.
The W5-JEM1 does not interpret the data being transmitted across it, and so the transferred messages may contain data of any nature or definition. This allows you to use the same gateway for many different serial protocols.
The W5-JEM1 permits communication with serial peripheral devices in the same fashion as the other EtherNet/IP products in the system. Data may be read/written using either I/O messaging or explicit messaging.
The W5-JEM1 has a 9-pin D-sub connector for connection to the serial interface port on your devices, two RJ45 connectors for connections to the EtherNet/IP network, and one 3-pin connector for power and grounding. The W5-JEM1 serial parameters are software-configurable. Each W5-JEM1 has 2 standard green/red EtherNet/IP LED’s for module status and network status and two green LED’s for each serial port to indicate transmit and receive activity.

3 Hardware Installation and Set-Up
3.1 Installation
Follow the steps below:
1. In most cases it is recommended to set the device’s IP address prior to installation. See section
5.7 “Setting the Device IP Address” if required. a. The factory default IP address is 192.168.1.10 for all units
2. Mount unit onto DIN rail
3. Wire up power (24VDC typical), common, and chassis ground to the power connector. See section
2.3 “Connector Pinouts” for a diagram. a. If there is no chassis ground connection or the power supply is connected to chassis
ground, jumper the chassis ground connection to the common connection
4. Connect the device to the controlling PLC with an Ethernet cable a. The device may be connected directly or through an ethernet switch
5. Connect the W5-JEM1 to the serial device using a compatible serial cable a. This device requires serial cables with a special pinout. See section 3.5 “Serial Wiring
Diagrams” and section 2.3 “Connector Pinouts” for further information.
6. Apply power, device is ready for use with PLC.
7. Also see section 4 “Software Quick Start” for an explanation of how to use the W5-JEM1 with a
PLC
3.2 Power Supply
The device is intended to be used with standard 24V DC industrial power supplies. However, any voltage between 5V and 28V may be supplied to the device assuming sufficient current is provided.
3.3 Network Connection
The device must be connected to the controlling PLC either directly with a cable or through your local network Ethernet switch. Shown below is a diagram of some typical network setups when using a Rockwell PLC.
