PL2303 with Arduino UNO

Hi, I am using the PL2303 serial communication device to try and upload my code in a stand alone Arduino. my connection is as follows:
5V---> 5V
GND---> GND
TX---> RX
RX---> TX
There is no DTR or RST pin
and i keep getting " an error occured while uploading the sketch" how can solve this problem?
thank you in advance.

When the IDE shows the sketch size, tap the RESET button on your stand alone.

Thank you so much!!

Happy to help.
