r/PLC on Reddit: USB to serial adapter driver
March 26, 2025 -
Hey yall. New to the automation world. I've got a SLC5 that I'm trying to go online with using an rs232 adapter. I'm missing the driver. The adapter is old as hell so I cant tell the brand. Do I need to download the driver straight from the manufacturer's website? Or is there a general driver i could download.
Ive done this before using different adapters, but I knew the manufacturer in those cases
Thanks

Look in Device Mangler in the device properties and get the hardware ID. Then Google that, and it should point you at the adapter or chipset mfgr's website, to download the driver. For future though, just buy one based on an FTDI chip and it'll plug and play in Windows. Other common chips will too, but FTDI seems to be the most reliable in operation.

The adapter should have a part number on it.

Click to expand... The settings have nothing to do with "the cable" (i.e. the RS232-to-USB adapter) but rather the device itself. If you have a working serial connection you can use whatever adapter you want as long as you have a working driver for it. More on forums.freebsd.org

March 26, 2025Issues with rs232 serial to USB driver on Windows 11
Best option is to roll back to win10. Win11 has too much issues with serial or rs232 drivers. As a network engineer i have to console eah day. So we have two types...prolific and ch340. Win10 works fine with the built in ch340 chipset and can console to every switch/router. Prolific works if you manually install the latest driver. But in win11 i had endless issues with both chipsets..even if they say win11 compatible. More on reddit.com

October 29, 2021 - Yeah, keep in mind those USB-to-Serial adapters can have different chipsets, it's never just some wires. FTDI is a common USB serial chip, but there are others. Even if you buy two USB-to-Serial cables from the same vendor you can get different chipsets in them. I have a bunch of those cheap Sweex USB-to-Serial converters and they all use different chips. Super annoying. ... Click to expand... On windwos i've installed driver called 'ch340ser-wimdows.zip', and Yes I didnot miss spelled it.
