Hi all,

I am trying to implement USB to RS232 converter using DLP2232M module which uses FT2232C(FTDI chip).

My connections are for USB self-powered configuration ( pins 17,18,19 connected to external +5V, while pins 22,23,24,25 are grounded).

I have downloaded Combined Driver Model CDM 2.00 from FTDI website, unzipped and installed.

On hooking the circuit, the PC detects it and after installation, it recognises the module as USB serial converter A and USB serial converter B.

But the device is not listed as virtual com port like com2,com3 or com4 so that it can be used as RS232 port. What could be the problem? Any suggestions to make the DLP2232M to work?

Thanks in advance
