S2C D-MAC Emulator



Overview

The S2C D-MAC Emulator is a software tool that offers extra flexibility for underwater network protocol developers and end-users of EvoLogics underwater acoustic modems and positioning systems.


A real-time emulator of the S2CR-series underwater acoustic modems, this tool is aimed at optimizing underwater network protocol development by taking out expensive modem hardware from the early testing stages - it emulates all features of the modem's data-link protocol layer and includes a phenomenological simulator of the physical protocol layer.

  • A great learning tool for end-users of EvoLogics modems: get familiar with the command set without the hardware
  • Allows testing new underwater network protocols and/or application solutions without underwater modems
  • A time-saver for code debugging and refinement
  • Test the interface between your software development and the acoustic modems
  • Supports several virtual modems at once
  • Offers the freedom of working over remote access
  • Solutions, designed and tested with the emulator, are easy to export to modem hardware

Optimize Development Costs


Any code, written and run on the modem emulator, can be later run on the actual modem hardware without any modifications, offering a time-saving solution that minimizes development costs for upper layer network protocols and simplifies integration of acoustic modems into underwater infrastructure.

AVAILABLE OPTIONS

Remote access subscription

A network of virtual underwater acoustic modems is configured and run on EvoLogics server. Access to the emulated environment is granted over VPN.


The service is offered on a subscription basis.


Standalone device

Standalone hardware: the EMULATOR BOX does not require a connection to EvoLogics' servers and is run on the customer's premises.


Specifications subject to change without notice.
