[. . . ] External view and measurements of the device Dimension: 90 x 58 x 53 (mm) i DESCRIPTION OF THE DEVICE AND PRINCIPLES OF FUNCTIONING The device VRT014 consists of a microcontroller and GSM modem. There are 4 light diodes on the external board of the device as shown in picture 2. Picture 2. Device VRT014 The light diode Power is directly connected to the Power supply chain of the microcontroller. The light diode Modem State is connected to the GSM modem and its status depends on the operation logic of the GSM modem and its specifications (The diode may have no flashing). [. . . ] The light diodes Relay and Signal Strength are connected to the microcontroller and reflect the status of the device. The light diode Relay reflects the signal status of activating the internal relay. The light diode Signal Strength reflects the Power of the signal received via the GSM modem. When the Power is supplied, the light diodes Relay and Signal Strength reflect the start of activating the programme and its various stages. If the connection is correct, the light diodes are flashing alternately as specified in the table below, and when the operation status is activated, they are operating in accordance to their main functions. 3 When the Power is supplied, the device checks the whole internal data base of numbers and operation of the memory chip. If there is a memory error, the device would not switch to operation mode and 2 pulses would be emitted by alternately by the light diode Signal Strength. If the GSM modem is not functioning, the device would not switch to operation mode and uninterrupted swift short pulses would be emitted by the light diode Signal Strength. In the device, the whole internal data base of numbers is being checked by checking the control counting (CRC). If the control counting does not match, the device would rewrite all settings back to manufacturer's values: · The enabling of the external switch signal. Recording a number in the data base of numbers Recording the time of the delayed switching-off-the-relay signal Recording the status of receiving an external switching-on-the-relay signal SMS message containing a command for recording a number is as follows: P#nnn=xxxxxxx; The symbol "P" should be in the first position, instead of nnn there must be a number to be recorded in the device memory, xxxxxxx means a recorded phone number which the device would respond to. 5 Example: P#001=+37012345678; - this message means that the number +37012345678 must be recorded in the first (1) position. SMS message containing a command for recording the time of the delay of the relay is as follows: PRTIMT=xxxxx; The symbol "P" should be in the first position, xxxxx means the recorded time in miliseconds within which the relay would be delayed. Example: PRTIMT =5000; this message means that the relay must be delayed for 5 seconds after switching on. SMS message containing a command for recording the altered status of receiving an external signal (external switch) is as follows: PSEN=x; The symbol "P" should be in the first position, x may mean 0 or 1. 0 means that the device would switch ON the relay after the external signal has been received. Example: PSEN =0; means that the device would switch on the relay after the external signal has been received. One SMS message may contain several messages containing commands, and the messages must be separated by the symbol ";". Example: P#001=+37012345678;#002=+37023456789;RTIMT=5000;SEN=1; This message means that the number +37012345678 should be recorded in the 1 (first) position and the number +37023456789 in the 2 (second) position, the relay must be delayed for 5 seconds after switching on and the external switch signal is disabled. The changes take effect immediately after the reception of the SMS message. 6 i · · · CONFIGURATION BY MEANS OF A PERSONAL COMPUTER In order to configure the device using a personal computer you should: Install Remote Switch Configurator Connect VRT014 to a PC using a configuration cable Start Remote Switch Configurator In picture 4. It is divided into 3 sections Relay configuration Search of a number in the list The list of numbers Control buttons Picture 4. The main window of Remote Switch Configurator Configuration of relay allows the device to switch from ON to OFF mode of the inner relay. [. . . ] It is divided into 3 sections Relay configuration Search of a number in the list The list of numbers Control buttons Picture 4. The main window of Remote Switch Configurator Configuration of relay allows the device to switch from ON to OFF mode of the inner relay. Device can switch modes automatically after a number of ms, which can be entered in Relay Timeout (ms) field. If an external source of a signal (button or other sensor) will be required in order to switch ON mode, you should no place a tick at Disable External Switch. [. . . ]
