EKI-1331 cellular gateways can transparently bring RS-232/485 or Ethernet devices to a cellular network. They allow nearly any device with serial or Ethernet ports to connect and share a cellular network with easy and simple configuration. EKI-1331 cellular IP Gateway’s are compact, and can be DIN-rail or wall mounted and with front panel LED displays for easy identification. They come with DC power input from 12-24 VDC and have 2 KV EFT/Surge protection to prevent damage from various type of power resources. The serial ports are also protected by 15 KV ESD line protection to keep your system safe from unexpected electrical discharges. From the rugged design to the built in automatic recovery mechanisms, the EKI-1331 can ensure critical applications stay connected. While providing a suite of VPN features, the EKI-1331 guarantees data security.
