简介
E-Lins工业路由器经过专门设计，可安装在极端环境条件下，例如外部机架、城市元素（路灯、信息屏幕、公交车站等）、工业仓库、生产线、车辆、外部远程监控系统等。
这些工业路由器的设计和制造采用了高强度元件，无论是在电气还是机械方面，都优先考虑了耐极端温度，通过使用低功耗组件和增加通风来达到此目的。
E-Lins开发了一款工业无线路由器H685，它还具有ADSL功能。这款工业2G/3G/4G路由器具有特定的特性，使其能够满足公用事业市场（电力、燃气等供应商）的苛刻要求，从而使其符合大多数工业路由器场景。
产品功能
获取并分享2G/3G/4G的自由！H685 2G/3G/4G无线N路由器允许用户在2G/3G/4G覆盖范围内的几乎任何地方与机器共享移动2G/3G/4G宽带连接。插入SIM/UIM卡（某些网络将SIM/UIM卡刷入路由器），通过简单配置，即可创建蜂窝宽带连接，并立即建立Wi-Fi热点。
2G/3G/4G无线共享 H685系列路由器具有极高的速度，允许用户通过有线或无线连接与不同设备共享2G/3G/4G移动宽带。
现场测试——高兼容性
兼容性是选择2G/3G/4G路由器时最重要的考虑因素。为确保最佳兼容性，E-Lins已确保我们的3G/4G路由器与销售区域的ISP兼容。我们全球的团队不断测试我们的路由器与网络和运营商的兼容性，以确保最终用户可以放心地在他们生活和工作的地方无缝操作他们的路由器。
3G/4G和有线WAN连接冗余（备份策略）
H685路由器以其2G/3G/4G和WAN连接备份而脱颖而出，当一个连接失败时，它能保持用户在线。E-Lins的2G/3G/4G路由器为用户提供了2G/3G/4G优先和有线WAN优先两种备份模式，而其他品牌只提供其中一种。这为用户在考虑连接成本和停机时间时设置网络带来了高度的灵活性。
无线N速度和范围
H685路由器符合IEEE 802.11n标准，可建立传输速度高达150Mbps的WiFi无线网络，同时在小范围本地内，可减少长距离和穿透障碍物时的数据丢失。最重要的是，用户可以在距离路由器更远的地方轻松接收无线网络信号，而使用传统的11g产品时，他们必须离路由器更近。
亮点
兼容TDD-LTE/TD-SCDMA/TD-HSUPA/TD-HSDPA/EDGE/GPRS/GSM网络，经过现场测试（详情请参阅数据表）。2G/3G/4G和WAN连接备份保证“始终在线”的互联网连接

The H685T supports TDD-LTE Band 38 (2600 MHz), Band 39 (1900 MHz), Band 40 (2300 MHz) and Band 41 (2500/2600 MHz), with fallback to TD-SCDMA (2010–2025 / 1880–1920 MHz) and EDGE/GPRS/GSM quad-band (850/900/1800/1900 MHz). Other TDD-LTE band combinations are available on request — see the datasheet for the full band list.
Yes — the H685T is carrier-unlocked and accepts any standard SIM/UIM card. APN is auto-detected for most carriers. Before ordering, confirm your carrier operates TDD-LTE Bands 38/39/40/41; for FDD-LTE regions (most of Europe / the Americas), choose the H820 series instead.
Yes. With the RS232 or RS485 option (H685T-S / H685T-S485), the router works as a serial-to-cellular DTU gateway, transparently tunneling Modbus RTU traffic from meters, PLCs and RTUs to your SCADA center over TCP/UDP. Configuration takes minutes in the Web UI.
Insert an activated SIM, connect power (5–40 V DC — 12 V / 24 V cabinet and vehicle supplies work directly), attach the antenna, and the router registers on the network within about a minute. Default Web UI is at 192.168.8.1; APN, failover and VPN are configured in a guided flow. Most sites go from unboxing to online in under 10 minutes.
Yes — the compact metal enclosure is designed for street cabinets, pole boxes and control panels, with a −35 °C to +75 °C wide-temperature design and enhanced ventilation. Wall-mount and DIN-rail kits are available as accessories; the Hardware Installation Guide covers grounding and wiring.
Yes. The H685T supports three-way failover between 4G/3G/2G cellular, wired WAN (xDSL via RJ45) and Wi-Fi client mode. You can choose cellular-preferred or WAN-preferred backup strategies, and a built-in watchdog automatically restarts the link if the connection drops — an always-online design.
Yes — a full VPN suite: PPTP, L2TP, IPsec and GRE, with IPsec PKI digital certificates and extended authentication for compatibility with third-party VPN concentrators. IP/MAC filtering and an SPI firewall protect against DoS attacks.
All E-Lins routers integrate with the E-Lins NMS cloud network management system — remote monitoring, bulk configuration, firmware upgrades and alerts. SNMP (MIB-II + private MIB), Telnet, SSH2, Web UI and SMS status control are also built in. Learn about NMS →
Yes — firmware updates run over the Web UI, via the Configuration Tool over LAN, or in bulk through E-Lins NMS for entire fleets. Dual-image fallback means a failed update never bricks a remote unit; the step-by-step procedure is documented on the Wiki ("H685T Firmware Update Procedure").
Every H685T carries a 5-year limited hardware warranty, a 30-day return policy on standard units, and lifetime firmware updates. Extended warranty and advance-replacement SLAs are available for volume and OEM projects.
Yes. E-Lins has provided OEM/ODM services since 1999: custom firmware, branding, enclosure and feature options (RS232/RS485, GPS, SMS/voice control, RIP/OSPF/BGP, PoE). Evaluation customization starts from a single unit; production branding typically starts at 50 units.
Standard models have no MOQ — order one sample to validate your application. Standard lead time is 2–4 weeks depending on options and quantity; volume pricing starts at 10 units, OEM pricing at 50+. Request a quote and receive a formal offer within 4 business hours.
