Many items at NothingButSavings.com offer FREE Budget Shipping. Plus, as with many of our competitors which do offer free shipping, we don't ask you to spend a specified amount in order to qualify for FREE Budget Shipping.

1. Add the item(s) that qualifies for FREE Budget Shipping to your order's shopping cart.
2. If a product has our "Free Shipping" tag that item will qualify for FREE Buget Shipping regardless of its price.
3. Proceed to checkout and select Budget Shipping as your shipping option (items will take an additional 7-10 business days to ship).
4. Ship your item(s) to a valid U.S. address.
5. Then, complete your order. It's that simple!
6. FREE Budget Shipping excludes certain oversized and/or overweight items, and those products that do not include this tag.
Some items may be excluded:
If certain items in your shopping cart are not eligible for Budet Shipping then buedget Shipping will not be available and thus the offer for Free Budget Shipping will not apply.

These compact, isolated USB to RS-232 and USB to RS-422, and RS-485 converters allow you to add an asynchronous serial port to your USB only PC.

They are USB 2.0 compatible. Model USO9ML2 is the RS-232 version and supports hand shake signals as well as data at speeds up to 460.8 Kbps. Model USOPTL4 is the RS-422 and RS-485 version and supports data rates up to 460.8 Kbps. RS-485 2-Wire and 4-Wire modes are selected using a DIP Switch. If you don't need isolation, use model USPTL4. Windows operating systems up to Windows 7 (32 and 64 bit) are supported. The USOPTL4 is equipped with our signature high retention USB port. The RS-422/485 versions have a removable terminal block.
