DSF22 UNIQUE MONITORING TERMINAL
6
INSTALLATION AND SETUP GUIDE
Note!!!
Both diodes must be with appropriate forward current, at least 3 Amps, otherwise terminal may
have power drops during data transmissions.
Recommendation!
To keep backup battery charged, we suggest adding a resistor, connected to backup battery
positive terminal and vehicle’s ignition. This connection will provide small charge current for
backup battery during driving.
To activate SMS alert, follow these steps:
1. Set universal digital pin to digital input working mode, P35 must be set to 0;
2. Define User phone numbers to receive SMS alerts, set P42 and/or P48;
3. Enable digital Input status change alert, define alert condition; P62 set to 2
From this moment digital input status change alert is enabled, in case if voltage in green wire will be
lost, terminal will send SMS alert to defined numbers.
Note!!!
In case of digital input status changes, terminal will send only one SMS alert to each defined number,
after that digital input status change alarm becomes passive. Switch ignition ON and then OFF to
activate input status change alarm again.
