Direct query command set
The only command required for this product is to query the status of the inputs if
needed. This may need to be done after a server reboot in order to get the current
status of inputs on the controller. This will be done via a TCP socket connection
to the controller’s IP address on the port number configured in the Listening Port
field during WiFi module setup in Base Station. While these are technically A/D
inputs we are simply using them as contact closure inputs. All inputs are pulled
low on the controller so if the input is not tripped its value will be 0. When the
input is tripped it will be pulled high and its status will be 255. It is recommended
that you assume any input above 200 is tripped with a contact.
