Products Usage Instructions

Wiring and Installation

1. Connecting network line or RS232 serial port

2. Connecting the lamp and power into the corresponding output pole, according to      below diagram.

relay interface

3. When need to control one group or groups lights, connecting the line into the corresponding output poles.

4. Connecting the 12V power adapter to charge

5. When the detection sensors are available, connecting them into the input port.

Software Operation

1. Opening the network debugging tool to detect the IP address and port of the device (see below figure)

hardware config

2. Clicking【Device】, see below figurenetwork config

3. Double clicking 【the Name】, set up the network parameter of the device smart-home-config

4. Choosing the working mode, TCP is for local area network setting or secondary  development; UDP is for APP controlling.

5. Opening 【Relay】software, inputting IP address and port, clicking 【connecting】(see below figure)


6. It’s 8 ways, choosing 8 output is ok.


Secondary Development Communication Protocol

1. Relay Controlling(SET):


RETURN: RELAY-SET-x(1bytepack_num),x(1byterelayserialnumber),x(1byteaction0/1),



2. Relay Status(READ):


RETURN: RELAY-READ-x(1bytepack_num),x(1byterelayserialnumber),x(1bytestatus0/1),OK/ERROR


3. Input Status(GET_INPUT):


RETURN: RELAY-GET_INPUT-x(1bytepack_num),x(1bytestatus),OK/ERROR


4. Trigger Alarm(ALARM):



Re: Without receiving the RETURN, ALARM will be re-triggered every 3 seconds, totally re-triggered 3 times.


5. Scanning(SCAN_DEVICE):




6. Serial Number acquisition(HOST):

RELAY-HOST-NOW(under TCP working mode)

RETURN: HOST-CHKLIC-97813679bd8cc4c42ddb6c27(return host serial number)


7. Relay Groups Controlling(SET_ALL):


RETURN: RELAY-SET_ALL-x(1bytepack_num),D3,D2,D1,D0,OK/ERROR


8. Relay Groups Status(STATE):


RETURN: RELAY-STATE-x(1bytepack_num),D3,D2,D1,D0,OK/ERROR


9. Status Testing(TEST):



Re: under this status, the pack_num isn’t working.

Secondary Development Program Toolkit

We supply complete source program Toolkit of VS2005(Microsoft Visual Studio 2005) , and we give the controlling examples through RS232 serial port and Ethernet socket,to help customers carrying on the secondary development.

The upper monitor can control the relay switch, and also show the input state.Details showed from below screenshots.
