Tuflow and estry manual Version 3

4.1Installing a Dongle

A TUFLOW dongle is required to run TUFLOW, but is not required when using the GIS, text editor or viewing results in SMS.

Two types of dongles are provided:

• 
  Standalone Dongle – allows any number of TUFLOW processes to be run from the one computer.
  
• 
  Network Dongle – allows up to a specified limit the number of TUFLOW processes run from a computer network.
  

Dongles require a parallel or USB port and can be daisy chained with TUFLOW or other software dongles, printer cables, etc. USB dongles are only available from Build 2004-06-AC onwards. Version 1.05 of sl2inst.exe must be used for this build to work.
