    First Impression

The U0902A is a communication devices design for IPC. Provides a simple method of adapting legacy serial devices with RS232 9pin interfaces to modern USB 9pins ports.
This is accomplished by incorporating the industry standard FTDI FT232R USB-Serial bridge chip.
The integrated electronics of the U0902A utilize the FTDI FT232R and includes RS232 level shifters plus TXD/RXD LEDs to provide a visual indication of data traffic through the module solutions worldwide.
