ZXPand+ TTL Serial/USB cable (6 pin colored)

Post by tdg8934 » Thu Aug 03, 2017 7:43 pm

All,

I found what I believe is a USB to TTL Serial cable (6 pin colored) cable for a past micro-controller project (5vdc).

This should be the connections:

Code: Select all

Color    Name    Type     Description
Black    GND     GND      Device ground supply pin.
Brown    CTS#    Input    Clear to Send Control input / Handshake signal.
Red      VCC     Output   +5V output
Orange   TXD     Output   Transmit Asynchronous Data output.
Yellow   RXD     Input    Receive Asynchronous Data input.
Green    RTS#    Output   Request To Send Control Output / Handshake signal.
(EDITED in CODE window)

I'm hoping I can use the new SERIAL command and baudrate to use HyperTerminal or something to communicate to the ZX81/TS100 and also the Parallax Serial LCD I will connect to the IDC connector on the ZXPand+

Interesting test. My ZXPand+ should arrive any day now.

Tim

Tim, the forum software makes a mess of tables, so put your tables in a "code" box (the </> icon above the edit box) like so...
Note you do still have to play with the spaces a bit...

Perfect. That's a FTDI USBSerialTTL that is. I have a couple. Great kit. It's the same pinout as my 'super serial' board that is on GitHub if you care to peruse ;)
