thanks for your time and help.

listed below is what i was reading on the pdf. page 12. this might not be enough information for you but then again it might.

and if the netduino board can not handle that much current would i be abnle to add restistance to the line in return lowering the voltage so that reads below 20mA for alarm and even lower for standby?

 

what i am trying to do is make a functional security system using the honeywell key pad with my netduino. i want to keep all the function of the security keypad. so correct me if i am wrong. but with the current listed below if i program the netduino to light up an led with the alarm set and the sensor breaks connection would it work? and not light up the led if the keypad is set for standby and a sensor breaks?

 


 

DEVICE CURRENT # UNITS TOTAL CURRENT

 

6148 Fixed-Word Keypad 30mA standby/55mA alarm

my adviser (college teacher) has the all the necessary equipment to test this data line.

Do you think that data line pulses?
