## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA5446:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/ADA5446:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

This USB Type C cable adds a DB-9 (DE-9) serial port to your computer or laptop. Works with MacOS X, Linux, and Windows. Note that this provides (approximately) +-6V serial (RS232) not 5V serial (TTL), good for old devices like GPS, handhelds, programmers, etc with chunky DB9's on the side. Some cheaper RS232 cables 'cheat' and only give you 0-5V which won't work with some devices - this one has a true voltage doubler/inverter to make it more compatible.

These are tested and work great with bit-bang serial programmers and adapters - note that they are slow compared to hardware serial ports due to the high overhead of USB.

They're now FTDI-chip based for better performance and reliability. The drivers are rock solid and available for pretty much every operating system you will run across.

[If you need to use RS-232 with a computer that has only Type A ports, check out this cable here](https://core-electronics.com.au/usb-serial-converter-ft232rl.html).
