Hi,
I have a board with with a microcontroller. This board also has the serial port wired up and is provided with a female db9 connector. I want to connect this to another board that i will use for data transmission. The data transmission board has a female db9 connector too, I tried the following but in vain
1. use a male gender changer between the two boards - no interrupt on the controller side for the data that is sent
2. a null modem cable with female on one end and male on the other, i attached the gender changer to the female end and there is no communication either.
I have been searching the internet for cables that connect two DCE(modem) devices but havent found one.
Please let me know your suggestions.
TIA,
Bob
