    USB to RS-232 DB9 Serial Converter.

    Good cable for laptops that do not have a serial port. Great for programming and capturing serial data from telephone equipment. Good dealer and price. Drivers on enclosed CD or directly from Trend-net website. Very easy to install.

  • TRENDnet TU-S9 USB to Serial Converter cable

    I purchased the TRENDnet TU-S9 USB to Serial Converter cable to use with my UNIDEN Scanner Serial Programming Cable. Once having the cables connected together and connected to the computer, XP did its thing automatically and installed the drivers. After that I plugged in the BC346XT and running FreeScan was able to reprogram the BC346XT into a more logical order. The TRENDnet TU-S9 USB to Serial Converter cable works good. No problems at all with the cable. 5/20/16

  • RS-232 to USB cable and PL2303 driver

    Just what I needed to connect my Amiga 2000's null modem adapter to a PC laptop. This, plus a little software allows transfer of files between the Amiga and PC.
