# Max232 TX working but Rx not working

I have two PCB which has PIC32 as a Controller and two serial port. I tested the 1st PCB and serial port was working fine. I was able to send and receive data. But when I started testing the 2nd PCB, it was only sending the data but was not able to receive any data. I am testing it by using a simple UART code. Both the designs are same. The Tx Rx pins of the controller are connected to a MAX232 IC and from MAX232 IC, a serial connector is connected. I tested for any break in the track but everything seems to be alright. What can be the issue.?

• I can't see the schematic. Send it harder. – user65586 Mar 30 '16 at 16:55
