Note
Inputs ALARM 0, 1 are passive, a positive 3-15 V voltage should be applied for accepting
functions. For the contact activacion can be connect the positive potential from pin No.

TP – Time Pulsered
St – Status (in progress)green
The GPS is providing the correct data if the red LED is flashing to the rhythm of time pulses (typically
1 s).
