Is there any particular reason for using a console in this type of setup? Do people on site need to view the data etc
Depending whereabouts in the world you live, there may be little or no difference in the cost of buying an Envoy-based system vs a standard console. Here in the UK for instance, 6152+6510 is typically available as a discounted bundle whereas an Envoy system has to built up from its component parts.
So typically cost isn't a factor and many users will prefer to have the LCD screen available as a guide eg for setting up or troubleshooting checks, even if it's not going to be viewed routinely. It can also be handy to have the wireless diagnostic screens available if for any reason reception is marginal rather than easy.
The other pros and cons we've discussed before:
The Envoy console will auto-reboot, which can be a major plus, which the standard console cannot.
The Envoy console only takes AA batteries and so has much shorter life on internal batteries only.
If there is no other shelter available at the remote site and a Davis weatherproof box needs to be used then the Envoy will fit into the much cheaper 7728 shelter, whereas the std console needs the 7724 shelter.
