Connecting the temperature sensor and iButton key reader to Queclink GV300 / GV320 trackers
Queclink GV200 / GV200G, GV300 / GV320 car trackers have the ability to connect an external temperature sensor and iButton key reader to them. The temperature sensor can be used to monitor the temperature of the cargo being carried, and the iButton key reader can send a message to the server and control the status of one of the digital outputs of the tracker. This article describes the connection of the sensor and reader to the GV300 / GV320 trackers (the differences in these trackers are only in the number of supported GSM frequencies: 850/900/1800/1900 MHz and 900/1800 MHz, respectively).
The temperature sensor and the iButton reader are connected to the tracker through an optional interface conversion device (1-Wire / RS232-UART) type AC100. The AC100 is included in the 1-Wire Temperature Sensor Kits (kit with temperature sensor) and iButton Kits (kit with iButton key reader). To connect the AC100, the GV300 / GV320 tracker RS232-UART serial port is used.

To use the temperature sensor and iButton reader with the GV300 / GV320 tracker, you need:
The firmware version can be found by connecting the tracker to a computer and running a special program for setting trackers - Manage Tool. Select the Help menu, then About. In the window that appears, you can see the line with the firmware version in the tracker, for example, the following: Device Version: GV320R00A14V08M128_NMX
Firmware versions that support temperature sensor and iButton reader:
for GV300 - GV300R00A07V15M128_NMX and above
for GV320 - GV320R00A07V20M128_NMX and above
If the firmware version in the tracker is lower, then you need to update it. Instructions for updating the firmware in the tracker are given in the appropriate document (GV300 Track Air Interface Firmware Update V1.00 and GV320 Track Air Interface Firmware Update V1.00).
To work with the temperature sensor and iButton reader, you need to configure the following tracker parameters:
You can configure the tracker using the Manage Tool program or by sending several SMS messages with the corresponding commands to the tracker's SIM card number.
Together with the tracker, you can use one iButton reader and up to two temperature sensors. After connecting the new temperature sensors, you must reboot the tracker to determine them correctly.
To configure the serial port of the tracker, use the AT + GTURT command.
It determines which external device will operate the UART port, the exchange rate and the number of data bits, stop bits and parity in the parcel, as well as whether or not the power saving mode is enabled or disabled and whether digital input number 1 is allowed or not allowed to exit mode.
If you enable the power saving mode, the tracker’s response to the UART will become slow and to ensure a normal reaction, you must enable the tracker's wake up by affecting the digital input 1 (Input ID of Wakeup: Use digital input 1 to wakeup the device).
Setting up the UART using the Manage Tool:
- in the command browser (left panel of the Manage Tool program) select Other Settings;
- in the command browser, select the sub-item Serial Port Setting;
- in the settings panel of the command, set them in the following way:
Working Mode: Used for AC100 devices
Baudrate Index: 115200
Data Bits: 8
Parity Bits: None Parity
Stop Bits: 1
Sleep Enabled Disabled
Input ID: Wakeup: Do not use digital input to wakeup the device
Configuring UART2 tracker GV300 using SMS:
send a message with the following text from your phone to the SIM card number in the tracker: AT + GTURT = gv300,5,12,8,1,0,2,0 ,,, FFFF $
Configuring UART2 tracker GV320 using SMS:
send a message with the following text from your phone to the SIM card number in the tracker: AT + GTURT = gv320,5,12,8,1,0,2,0 ,,, FFFF $
The operation mode of the AC100 converter is configured using the AT + GTACD command.
Configuring the mode of operation of the AC100 converter using the Manage Tool:
- in the command browser (left panel of the Manage Tool program) select Other Settings;
- in the command browser, select the sub-item AC100 Devices Setting;
- in the settings panel of the command, set them in the following way:
I-button timer: 1 seconds
Temperature timer: 10 seconds
Output ID: 3
Out Status: check or uncheck
Duration: 0 x100ms
Toggle Times: 0
Comments on the parameters of the AC100 converter operation mode setting command:
- I-button timer sets the polling interval of the iButton key reader from 1 to 10 seconds, if set to 0, the reader will not be polled;
- Temperature timer sets the time interval for polling temperature sensors from 10 to 255 seconds; if set to 0, the sensor will not be polled;
- Output ID sets the number of the digital output on which the pulse signal will be generated if a key is applied to the reader. If Output ID = 0, then no digital output will be used to generate a pulse;
- Duration sets the pulse duration from 0 to 255 times 0.1 seconds;
- Toggle Times sets the number of pulses to be generated at the output from 0 to 255;
- Output Status is used only when Duration = 0 and Toggle Times = 0 and determines the state of the digital output after the end of the touch key to the reader. If Output Status 0, then the digital output is turned off, and if Output Status = 1, then the digital output is turned on, and it remains in this state all the time until the tracker is turned off.
Setting up the operation mode of the AC100 converter using SMS for the GV300 tracker:
send a message with the following text from your phone to the SIM card number in the tracker: AT + GTACD = gv300,1,3,0,0,0,10 ,,,,, FFFF $
Setting up the operation mode of the AC100 converter using SMS for the GV320 tracker:
send a message with the following text from your phone to the SIM card number in the tracker: AT + GTACD = gv320,1,3,0,0,0,10 ,,,,, FFFF $
IButton key can be used to turn off the ignition in the car. To do this, you must make the following settings:

AT + GTOUT = gv320,0 ,,, 0,0,0,1,0,0,0,, 0,0 ,,,, FFFF $
And connect the relay, switching the ignition circuit to digital output number 3. After energizing the tracker, it will turn on digital output 3, this will turn on the relay and power from the battery through the closed relay contacts will go to the car ignition lock. If you now touch the iButton key to the reader, the tracker will turn off output 3. The relay will also turn off, its contacts will open and the ignition lock will be de-energized. Further touches by the key to the reader will not lead to anything, the off state will remain until the next power off and on or reboot the tracker.
The temperature value is output by the tracker to the server in the message + RESP: GTERI (extended message about fixing coordinates). To configure the tracker in the mode of issuing such messages, you need to set to 1 bit number 1 in the ERI Mask bit mask of the AT + GTFRI command.

If the authorization mode via smart cards is enabled, the tracker will not issue messages to the server when the iButton keys are touched to the reader.
The authorization parameters are configured using the AT + GTIDA command. It allows you to allow or prohibit the use of authorization, configure the mode of sending authorization messages, create a list with smart card ID numbers, set a time interval for which no authorization will be needed again, and also assign a digital output that will control external relays, contacts which can be used to de-energize the starter or fuel pump. However, all these features are not used when working with iButton keys and authorization must be disabled.

The connection diagram of the temperature sensor and the iButton reader is shown in the figure below:
To ensure greater noise immunity, it is necessary to place the AC100 converter next to the tracker so that the length of the wires between them is no more than 50 centimeters. The AC100 power wire (VCC-AC100) must be connected to the contact wire 11 of the GV300 / GV320 tracker connector so that the total length of the wire through which the tracker power current and AC100 power current flows is as short as possible, no longer than 10 centimeters. Similarly, you need to connect the GND-AC100 common wire to pin 6 of the GV300 / GV320 tracker connector.
