Other Parts Discussed in Thread: TRS3232E
I am using the TRS3232E to interface an embedded system to a serial port on a PC. The TX waveform from the DOUT pin of the TRS3232E looks correct when there is nothing connected (open circuit). When it is connected to the PC serial port, the waveform becomes severely distorted.
It would appear the distortion is related to the loading effect of the PC serial port.
I am using capacitor values recommended in the data sheet. Can the distortion be corrected by selecting different capacitor values for the TRS3232E?
The exact capacitors I am using are:
Thanks for looking.
