Several new “undocumented” features that can be useful for you.
1. All Eurosens Dominator RS sensors can work in frequency output mode same as Eurosens Dominator AF. Just turn frequency output ON in the sensor configuration. Frequency output has customizable range (500-1500 Hz or other) and you will have this signal at “K-Line” wire of Eurosens Dominator RS cable (blue wire).
2. The same “K-line” wire of Dominator RS you can use for remote sensor disconnection monitoring. Just connect this wire (with frequency output option “OFF”) to analog input of the GSM terminal. When the sensor is connected – at this wire will be constant voltage level, approximately equal to half the supply voltage. When sensor is disconnected – this voltage level will be turned to “0” immediately.
