|Banner Wireless I/O Modules|
The hot topic in just about any article you read or hear about is going wireless. There are many products available but Banner has a product which helps take the guess work out of the application with their DX80 line of Products. Probably the biggest single issue of whether to use a wireless unit is whether it is going to work or not. With the Banner DX80 system a site survey can easily determine this. All that is required are the DX80 modules themselves.
By going through a couple of pushbutton commands, the strength of signal is shown on the unit display and without any other device (such as a laptop) you know the application will work and how well it will work.
For an example of a site survey and to see the modules go to the link below for a sample demonstration.
