H685mg gprs industrial routerNewly published 2G GPRS Industrial Router H685mg is specially designed for industrial application. Durable, flexible, and user-friendly feature is widely used for different kinds of high data transmission applications.

E-Lins industrial mobile router establishes a secure, high-speed GSM/GPRS/EDGE or UMTS/HSDPA connection for up to 4 Ethernet devices, E-Lins Cellular Routers are industrial design, and support redundant power at 9V to 48 VDC and operating temperatures from -30° to 75°C, which is special suitable for different kinds of complex and dicky environment.


The E-Lins H685vg GPRS Router is designed for compact and cost-effective solution for easily connecting machines or computers on a LAN network to Internet/Intranet through GPRS cellular networks.


E-Lins H685vg GPRS Router provides a RJ45 ethernet port for machine communication connnection.


The H685vg cellular router is a GPRS router designed to be compatible with the current and future requirements of remote telemetry and industrial control systems applications. The unit has an integral Ethernet port and a 25 pin RS-232 serial interface for local connectivity. The inbuilt RS-232 port can be used to connect legacy serial based equipment such as PLCs, RTUs or IEDs.  Owning an integrated stateful inspection firewall and IPSEC VPN (Virtual Private Network), H685g GPRS router can be used with the latest security technology to resist denial of service attacks and hacking. The VPN’s can be used as a way of increasing security and to create secure tunnels, running between sites. The VPNs can be used to interconnect the sites effectively replacing the requirement for dedicated leased lines.

2.5G mobile communication technology (GPRS) has become widely used of industrials and utilities in recent years and many customers are seeking reliable, flexible and cost-effective data channel to build their information system. Many applications such as ATM, POS, SCADA and surveillance system will require data channels covered all country; this brings a bright future for GPRS data networks applications.Requirements towards information system are varied because of different features of numerous industrial applications. Mobile telecom service providers are required to provide industrial application solutions not only meeting common specifications and also individual special ones.

Ethernet is migrating from traditional IT equipment and being adopted as a standard interface for many types of machines, however challenges arise at customers sites where the LAN infrastructure is outside your control.

The wireless router creating a standalone network, where access to attached LAN-based devices is gained over wireless network for control and monitoring purposes.

The H685vg GSM Router is easy to install reducing the reliance on the end customer and enables direct access to your remote LAN devices for control and monitoring purposes.

It enables companies to remotely access equipment at mobile, remote networks and isolated sites.

GPRS Router offers wireless network routing optimised for machines, small networks and specialised Fixed IP services now available from wireless operators. It offers low cost router operation through Dial-out, Dial-in and Always Connected modes of operation.

The 3G Wireless Industrial Router is designed for establish a Wi-Fi wireless network and share a cellular broad band Internet connection. The 3G Cellular Router enables users to quickly create a secure Wi-Fi (802.11 b/g/n) network and provide access to the Internet using a cellular network. By connect to HSDPA network; an Internet connection can be accessed and shared virtually anywhere within a wireless broadband network.


E-Lins’ 3g industrial routers are widely used in more than 50 countries and regions, and more than twenty industrial fields, such as power control, water schedule, traffic, oil field, weather forecast, environmental protection, street lamp control, post, bank and many other areas.
