7. Connecting
7.1. Inserting SIM-card
Use a SIM-card with activated GPRS and SMS services.
Insert the card carefully without applying excessive force .
To eject SIM-card, press it.

Description
3 GSM-module is switched on
2 GLONASS-module is switched on
1 GLONASS and GSM-modules are switched off, Tracker is in operating mode.
8. Description of Tracker units’ operating
8.1. Description of universal input operation in analog mode
To attach external sensors, the tracker has a universal input, which, in accordance with settings, can be
analog-frequency input or interface 1-Wire. Input function is set in Tracker settings (see section
Inputs/outputs ). In section Contacts description input is set as IN.
Input specifications in analog mode:
Feature Value
Maximum measured voltage 33 V
ADC resolution 12 bit
Maximum transmitted signal frequency 4 kHz
In analog mode input has the following settings:
Parameter Explanation
Filter type (input
function)
0 - arithmetical average (also discrete input state is generated);
2 – frequency input.
Filter length to
calculate the mean
value
The greater this parameter, the more slowly the device responds to the input signal
change. With filter length equal to 1 - averaging does not happen.
It is necessary to set this parameter in 1 for frequency inputs.
Ranges for
response/
nonresponse areas
(logical 1 and 0)
To process discrete signals, it is needed to set ranges, where signal is equal to one
and zero. Discrete input statuses should be seen in the Status of Inputs field, but not
in the Input voltage.
While counting pulses or frequency, it is necessary to put the value equal to half the
pulse value into all the fields of the given group. (example: the pulses' amplitude is
5000 mV, so all the fields must take the value 2500 mV).
