GSM Gate Opener and Remote Controller

RC11 is a GSM communicator that can be used for remote controlling and for notification sending. The
device has an optocoupler input and a potential independent relayed output that has normally closed (NC) and
normally open (NO) terminals as well. If there is a change on the input it will send only SMS or an SMS and a
call to a phone number. Output control is achieved by calling the module. Depending o n the setting controlling
can be made with or without caller identification. Output can be set to switch to its other state when called or
to switch for a given time to its other state from its default. Module settings can be adjusted by using DIP
switches and SMSs.
