Product description

1 channel SMS controller

Product introduction

Power supply interface: Power supply voltage: 6V-18V When using A 6V powersupply,ensure that the current is 1.5A or above.

Relay output interface: 250V10A relay,can directly operate most electrical appliances in the market.

SlM card holder: Insert SIM card in case of system power failure. Support mobile,J2G3G4G card, does not support telecom card.

Reserved interface: the reserved interface is upgraded to a switching interface.The signal detected is in a changing state,that is, the changing proce of the reserved interface from disconnected to connected.Through this interface, you can detect external signals and send SMS prompts to users.Currently, the software is supported, but the hardware is not supported by default.

Directions for use

For the following example, aume that the device key is 123456 and the authorization number is 18846919911.

Authorization number configuration:

format: *key *# 11-digit phone number #.Ar the configuration is succeful, the device will reply a text meage containing the 11-digit phone number set OK.The command sent is:*123456*#18846919911#.The system replies sYs Number: 18846919911 set OK.

Key setting:

format:* Key ** 6-bit key *.Ar the setting is succeful, the device will reply a meage with the content as follows: 6 digit key set OK. For ex ample, if the system key is 123456 and the key to be changed is 666666, run the following command:*123456**666666* The system replies with SYs Code: 6 66666 Set OK.

Switch alarm content setting:

format:* key *& content &, the content can only support digits, punctuation marks or letters,the maximum length is 11.Ar theSettings are succeful,the device sends an SMS meage containing the following contents: SYS ArmMeage: Set oK.For example, if the system key is 123456 and the content to be changed is ceshil, run the following command:*123456*& ceshi1&the system replies with the SYs Arm Meage: ceshi1 Set OK.Control device working mode: there are 4 kinds. Format:* key *So0000x$ wher e X is 1234.Ar the setting is succeful, the device replies with the meage SYs Mode: X Set OK! . lIf the device is configured to work in 1 mode, send the command:*123456*SO00001$, and the system replies with the meage: SYsMode: 1 Set OK!

Following describes the control mode in various modes:

1. When the device works in mode 1: The mobile phone rings. When the relay on the device is disconnected, the user makes a phone call to the card in the device with the authorized mobile phone, the bell will be automatically hung up ar 3 rings, and the relay will be in the suction state.The user is making a phonecall to the device with a mobile phone.The second ring is automatically hung up and the relay is disconnected. In this control mode, the state of the relay willbe saved.

2. When the device works in mode 2: mobile phone control.The user uses the authorized mobile phone to call the card in the device.Ar the call is connected (not connected), the relay will be in the suction state.Ar the user hangs upthe phone or fails to answer the phone due to timeout, the relay is disconnected.This control mode,the relay state is not saved.

3.When the device works in mode 3, that is,mobile phone tap control.The usercalls the card in the device with an authorized mobile phone. When the caloes through, the relay will merge for 1-2 seconds.Then the relay is disconnectedand the call is automatically hung up. This control mode, the relay state is not saved.

4. When the device works in mode 4, that is,SMS control. When the user sendsa switch to the device from an authorized mobile phone,the relay closes or disconnects.For these two commands, the relay state is saved; When the user sends a point command to the device with an authorized mobile phone,the relay will absorb and merge for 1-2 seconds, and then the relay is in the disconnected state.The state of the relay will not be saved by this command. When the user sends an on + time command to the device from an authorized mobile phone, the relay will merge the command and continue for the length of time set by the user, and then the relay will be in the off state.This command will not save the state of the relay.

User only needs to send a word, on,off, check command,can control the relay switch and query relay command. If the user controls the relay to close, the meage content is: open.

Begin to use

There are three steps in total: 1 is hardware connection; 2 is to send SMS to modify device ; 3 is to make a phone call or send SMS control relay.

Hardware preparations:

Ar getting the device，insert a SlM card (mobile or Unicom card) and power the device.Ar the D2 indicator on the device blinks, the system starts to sendSMs meages to configure the controller.

SMs configuration:

First, an authorization meage is sent,which allows the device to identify which phone number can control the device. For example,13477773699 is A number,and 15556664464 is B number.Edit SMS *123456*#15556664464# with any mobile phone card and send it to A number. Ar the modification is succeful, the mobile phone receives A reply meage from the device.The user can also send a meage to change the secret key (whether the secret key is changeddoes not affect the voltage output of the configuration control pin,just for safety, to avoid other people to change the system maliciously).

Working status of SMS configuration relay:

Ar the above work is completed, the mobile phone inserted into CARD B canbe used to send on, off,check and other commands to the device(card A) for control and query the device status.

When a user sends a timing command, the content of the SMS meage is set tothe specified time.Currently, the timing time ranges from 1 to 99 minutes. If the time is le than 10 minutes,0 must be added before the time. If the user needs to set the time interval for 1 minute,the meage content is set to 01.lf thecustomer needs to set the time interval for 11 minutes,the meage content is set to 11.

Product introduction

Overall d escription:

1. Control or query the relay output or status of the device by sending SMS meages with the contents of on 1,off 1, on 2,Off 2,and query.

The status of the relay is stored in the device and can be restored to the state before power failure when it is powered on again. Control can only be sent by authorized numbers，which are saved in the device.

3.You can change the authorization number by SMS. When changing the authorization number，you need to verify the change with a key saved in the device.The secret key can be changed by SMS, and the previous key authentication is required to change the secret key.

Hardware interface description:
