Low-Power Global LTE Cat M Modem with GPIO

The ZETA-NEP-LTEM (GL) is a cutting edge, low power industrial modem with general purpose interfaces. It will connect equipment to the new global LTE Cat M and NB IoT networks as they become available also providing backwards compatibility to the existing global 2G / GSM cellular network. The modem operates in a low power state which makes it ideal for use in industrial IoT applications today and for long term future developments.

The unique feature of the ZETA-NEP-LTEM (GL) allows it to run in a low power state due to its intelligent power saving design whilst monitoring general purpose inputs and driving full specification outputs. Additionally the range offers interface options including legacy RS232 for connection to existing equipment and a high speed USB interface.

The multi-function header also offers the following interfaces to the user:

  • 3 x General Purpose Inputs (0V-42V tolerant)
  • 2 x General Purpose Outputs (0V-42V @ 1A)
  • 1 x Analogue to Digital Interface (0-42V range)
  • 1 x RS232 debug serial port (3-wire interface)
  • 1 x Peripheral Power Interface / Output Supply (Vcc)

The powerful C development environment reduces redundancy and lowers system component costs, allowing developers to maximise the power of their application directly on the device and eliminating the requirement for an external microcontroller. The application programming environment can provide cloud edge processing for interfacing to equipment in the field and offers the ability to make intelligent decisions without requiring a permanent online connection to a gateway server.

As a result the ZETA-NEP-LTEM (GL) lends itself to rapid proof-of-concept developments with minimal investment, providing fast time to market and maximum scalability offering intelligence and decision making at the cloud edge.

linkCONNECT - Intelligent Management Solution

Siretta industrial managed modem solutions are intelligent modems which have been designed to connect remote equipment over a TCP/IP connection to a central location. Very little knowledge is required to setup the modem and configure the Siretta linkCONNECT solution. The unit can be setup to operate out-of-the-box and configured remotely via SMS once in the field or alternatively it can be pre-configured before deployment via a serial configuration tool.

The configuration of the managed modem solutions is controlled by the user simply using command SMS messages sent from a standard mobile phone. Alternatively when configuring large volumes of units there is a configuration tool which configures the unit over RS232 serial and can be replicated very quickly to aid the production programming. The configuration can be saved to a ‘.gtc’ file which can be deployed and re-used in multiple locations and production environments.

  • Automatic network detection and setup
  • Automatic APN setup (standard on UK networks)
  • Remote SMS configuration
  • Cellular and GPRS keepalive with mulitple options
  • Configurable automatic reboot timer
  • Configurable connection timeout
  • CSD backup for GPRS failure
