K8048 PIC Experemental board

[Pat]

Need advice please, when i try to download a program, SW5 set to 'Prog', LED's, LD8 steady and LD9 flashing, I get a message 'K8048 not found on Com1' , and LD8 goes dark.
I now have the comms cable wired pin to pin 2-2, 3-3 etc.
I have tried all handshaking options for the port on my PC.
I have also replaced the PIC, 16F627.
Can anyone help please.

Check that asll components are in right place.

Check you have proper power supply connected to circuit.

Recheck the cable.

Tell what operating system you run in your computer.

Hi. I have the same problem. The programmer work OK with PC Desktop, but in my Laptop, appear the message: ""K8048 not found at COM1".... I don't know but may be beacuse of the voltage levels....

Please, if you find the solution, write me... please!!!

Thanks,

Change the serial cable to another one. I had the same problem and the solution was to change the cable.
