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),D0,OK/ERROR


8. Relay Groups Status(STATE):


RETURN: RELAY-STATE-x(1bytepack_num),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 PC software can control the relay switch, and also show the input state.

Details showed from below screenshots.

We can supply the DEMO code of C++Builder, Delphi, VB.Net, Python , Andorid and iOS versoins.

This is a Hello World hareware verion of Demo code.

Follows are our demo video on youtube can help you(The video is KC868-H32 for 32 relays. Because of  KC868-H8 and KC868-H32 using the same communication protocol, so you can refer to the videos below. KC868-H8 have 8 relays, KC868-H32 have 32 relays):
