But I can get it to work using LC Technology's own windows based serial coms client. You can download it along with a user guide for the relay module from:

Good luck.

#65332 Hi,
I tryed even with the lc official program from the link above. but my relays doesn't works...
Can some one please explain me how to use the lc program or what i am doing wrong ?

I tryed:
connect 5V to the board ( i tryed 7v with the same resault )
connect the serial to ttl ( i sent and recieved AT commands using the lc program)
in the lc tool i typed A00101A2 , send as HEX , press send and nothing happend....

What i did wrong?

Thanks
Benny


UPDATE:
I think, i have found the problem:
in both my boards the resistors R3 = 4.7Kohm and R4 = 10Kohm, but according to the datasheet they should be R3=10Kohm and R4 = 4.7Kohm
