    I'm new to multi-video recording and I have a question - does the RS232 allow me to plug the USB end into a laptop and use with the software ProPresenter so that I can view each camera from this switcher? And also switch views from the software?? Hope I'm making sense...

    BEST ANSWER: No, the RS232 port is only for controlling the switch. There's no way to view any video over the RS232 port. Video only goes out over the BNC connector labeled "OUT". You can use software to switch the output but I don't see any documentation that suggests ProPresenter knows how to control this device.
    How long is the cable on this?
    A shopper on Nov 13, 2017
    BEST ANSWER: It is about 5 feet long.

    Got it working in Win 7 64-bit
    I had the same stupid problem with "error code 10" after installing the latest drivers from Prolific that everyone else listed. A Monoprice RMA support person referred me to the driver at the following link, which worked for me. It had the error immediately after I ran the installation, but it started working a moment later (apparently it took a moment for Windows to get it going after the installation).

    Essential Item for any Tech's Kit
    This USB-to-RS232 cable is the core item in provisioning a full RS232 serial port communication capability for your PC, Mac, or laptop. Note that RS232 is no longer routinely provided in most electronic components in favor of Bluetooth, WiFi, Ethernet, USB, or other communication interfaces. That said, RS232 is still widely encountered in current industrial applications, custom audio-visual control applications, and especially when dealing with older, still useful devices of various makes, models, and applications. In order to connect and communicate successfully with the various RS232 connectors found in the field, this comm cable only requires the addition of a few other Monoprice items:

    Item 1170 - Gender changer for 25-pin connectors

    Item 1186 - Gender changer for 9-pin connectors

    Item 1203 - Null modem adapter (9-pin)

    With the addition of these three adapters, there is no DB9 or DB25 serial connection to a USB port that cannot be made. In conclusion, an investment of less than $15 will provide any tech with a bulletproof capability to deal with RS232 communication challenges whenever and wherever they appear. Nice job, Monoprice!

    PROS: - Superior construction

    - Variety of drivers available

    - Attractive connectors and cabling

    CONS: None
