2.1.3. Connectivity
WiFi connectivity. The antenna supplied with the device must be connected to the indicated
connector in order to use WiFi capabilities. In case the signal is not strong enough, a more
powerful antenna can be used.
Mobile network connectivity. The antenna supplied with the device must be connected to the
indicated connector in order to get signal from mobile networks. In case the signal is not strong
enough, a more powerful antenna can be used.

2.1.4. Configuration button (SMART)
This button allows to execute configuration actions. Press and hold the defined seconds to run the
associated action. The following ones are predefined:
•Automatic autodialer configuration: hold pressed between 2 and 6 seconds with the device
connected to only one elevator car. During the configuration the connectivity LED ( ) will remain lit
and will blink when the process ends successfully. In case the configuration is not successful, the
light indicator will turn off without blinking previously. This feature is only available for 72horas
customers using GSR devices and autodialers available in the platform. GSR users who are not
72horas customers can use this 2 to 6 seconds button press for a custom action.
•Factory reset: hold pressed between 15 and 60 seconds. All LED lights will turn on and off after
the device is reset to factory settings.
•Local configuration of the device / Offline mode: This mode allows you to make changes to the
device’s configuration when it does not have access to the internet. To use it, it is necessary to
download the Nayar Systems application. Download links: Android /iOS. Once the application is
open, click on “Device local configuration” and follow the steps described in the assistant.

2.2. Device rear panel
At the rear panel of the device can be found the following information:
DC IN
Input for the power supply. When possible, the device must be always powered with the original power
supply. In case the original power supply can not be used, it is recommended to use a 18V-24V and 2A
power unit for an optimal battery charge.
ON / OFF
Button used for turning ON or OFF the device. When OFF, all current passage is interrupted from both
power supply and the battery.
12V OUT
12V output with polarity as indicated in the graphic. It can be used to connect several autodialers in
case they need external power, taking into consideration that the maximal supported current is 1A.
WAN/LAN
•WAN: RJ45 connector to receive internet connectivity from other devices.
•LAN: RJ45 connector to supply internet connectivity to other devices.
PHONE / CAN
GSR can be connected to autodialers through the integrated SLIC or CAN modules. To do so, the
device has terminal connectors that must be used as described:
Nayar Systems GSR - 1_en
Page 11 of 35

•1 y 2 (phone line): the pair of phone line wires or TIP and RING have
to be connected to the first two positions as indicated. The order of the
connectors does not affect the signal.
•H, L and GND (CAN connection): to ensure a correct operation,
special attention must be paid when connecting H, L and GND. Please
follow the indica ted steps.
USB
Compatible with USB 2.0 (0.5A) devices like for example expansion modules, a bluetooth adaptor, a
webcam, etc.

4. SMS Configuration
GSR’s configuration parameters can be programmed sending SMS messages to the device. The
accepted format is as follows:
password,command,command, … ,command
A sequence is created starting with the password and continuing with a list of commands separated by
commas ( , ). The default password is 12345.
The commands used for the SMS configuration are:
•Sis used for configuring a parameter. The structure begins with ( S ), followed by colon ( : ), the
parameter to set, colon again ( : ) and the value assigned to that parameter.
•Cis used to run commands. The structure begins with ( C ), followed by colon ( : ) and the
command to run. Certain commands also use values, in these cases add colon again ( : ) and set
the value.
• Add Wat the end of the SMS to save the changes introduced through that particular message. In
case this command is not added, the changes will be lost after rebooting the device.
•Gis used to consult a parameter. The structure begins with ( G ) followed by colon ( : ) and the
parameter to consult. A response will be received with its current value.
Here follows an example:
Perform the following actions according to listed commands:
Nayar Systems GSR - 1_en

4.1. Consulting a parameter
G command is used to consult parameters as shown in the following example:
12345,G:$tro1
Response:
[“parametre_value_$tro1”]

4.2. APN configuration
The APN the device uses can be configured with the following parameters:
$apn – to set up UPN adres
$apnu – to set up user
$apnp – to set up password
The following SMS is an example of how to configure correctly APN settings:
12345,S:$apn:“apnaddress.com”,S:$apnu:“user”,S:$apnp:“password”
Response:
[“OK”,“OK”,“OK”]
This example sets the APN apnaddress.com ($apn) with the user user ($apnu) and the password
password ($apnp). These values must be inside quotation marks ( “ ) when setting up APN
configuration.
