Description
🔧 Product Overview
The ProSoft ICX35-HWC-E is an Industrial Cellular Gateway designed for remote access, SCADA connectivity, telemetry, and machine-to-machine communication. It provides cellular connectivity together with Ethernet and serial interfaces, allowing industrial equipment at remote or difficult-to-access locations to communicate with control systems and networks.
The ICX35-HWC-E is the ETSI version of the ICX35-HWC family. It supports 4G LTE cellular communication with 3G fallback and provides an onboard 10/100 Base-T Ethernet port that can be configured for WAN or LAN operation. The gateway also includes a DB9 serial interface for serial tunneling and encapsulation.
ProSoft currently identifies the ICX35-HWC-E as a discontinued ETSI model, making available surplus units useful for maintaining existing installations where replacement with the same hardware is preferred.

🌐 Remote Connectivity
The ICX35-HWC-E is designed for installations where PLCs, RTUs, HMIs, and other automation equipment need to be accessed from a remote location.
Typical communication architecture can use the cellular network as the connection between a remote machine and a control center. The Ethernet interface can connect to an industrial network, while the DB9 serial interface can provide access to legacy serial equipment.
The gateway supports EtherNet/IP and Modbus TCP/IP communications, allowing compatible PLC or PAC systems to obtain gateway diagnostic information such as cellular signal and data-related information.
📡 Cellular Communication
The ICX35-HWC-E supports multiple cellular technologies and ETSI-oriented frequency bands:
- LTE Bands 1, 3, 7, 8, 20
- HSPA/HSPA+ Bands 1, 2, 5, 8
- Quad-band EDGE/GPRS/GSM
- SIM-based network activation
Two RP-SMA antenna connectors are provided. Antennas are separate components and should be selected according to the installation and supported cellular network.
🔐 Security & Remote Access
Security functions include OpenVPN client, IPSec client, and IP address filtering. The gateway also supports secure remote connectivity architectures through ProSoft/Belden remote-access solutions.
The built-in web server provides access to local or remote configuration, monitoring, and wireless network diagnostics.
🏭 Typical Applications
The ICX35-HWC-E can be found in applications such as:
- Remote PLC access
- SCADA systems
- Remote telemetry
- Water and wastewater systems
- Oil and gas equipment
- Pumping stations
- Industrial machinery
- Remote production equipment
- OEM machine monitoring
- M2M communication
- Legacy serial equipment connected to cellular networks
- Distributed industrial automation
For geographically dispersed installations, cellular communication can reduce the need for technicians to travel to remote equipment for routine diagnostics or troubleshooting.
🔌 Installation & Replacement Notes
Before replacing an existing ICX35-HWC-E, verify the exact regional model and cellular-band requirements. The E model is specifically the ETSI version and should not automatically be substituted with the FCC-oriented ICX35-HWC-A without checking the application.
Recommended replacement procedure:
- Confirm the original part number is ICX35-HWC-E.
- Verify the cellular network and supported LTE bands.
- Confirm the SIM card and carrier requirements.
- Check the existing antenna arrangement.
- Verify the 10/100 Ethernet connection.
- Check whether the application uses the DB9 serial interface.
- Record the existing network and VPN configuration.
- Verify the required power supply is within 10–30 VDC.
- Confirm adequate cellular signal at the installation location.
- Test Ethernet, serial communication, cellular registration, and remote access after installation.
Because the ICX35-HWC-E is discontinued, customers replacing an operating unit should verify compatibility carefully before changing to another cellular gateway model. ProSoft identifies the ICX35-HWC-A as the currently available FCC version while the ICX35-HWC-E is discontinued.
