About HT12D

Don't worry about Phil Allison - he's best dealt with by ignoring him.

Sorry I can't help you with your question, )-; but there are experts around here who probably can. :-)

Good Luck! Rich

Dear All,

I am using a HT12E & HT12D with a RF transmitter and a RF receiver to do a radio transmission link. Two serial clock pulse (30-100Hz) will be sent with this link. When I do the testing, the clock pulse can be sucessfully sent to the receiver. However, the clock pulse has been slowed down after the decoding. The output signal from the HT12D become very slow. Also, the HT12D will only output 'high' (5V) if I change the input frequency of the clock pulse below 80Hz or larger than 100Hz. That's mean, it only works with frequency range 80-100Hz and the outuput frequency is slowed down as well. How can I solve this problem? Thanks for your help.

Best Regards, Lok

Sorry, I can't really understand what do you mean...

Asinine, self appointed "net cops" are just about the lowest piles of scum on earth.

Yet they are 100 dB higher on the list than you.

Anyway, thanks for your reply.

I'm sorry I don't understand your question.

Which are the two serial clocks?

As far as I understand the bit rate of transmission is adjusted by Rosc, and the data is encoded from the data and address pins.

So where does the serial clock/clocks come into the picture?

Sorry if question is dumb!
