Believe me, it's easy. Here's the reference: https://z-uno.z-wave.me/Reference/Serial/ Here's the example using Serial and Serial0: https://z-uno.z-wave.me/examples/rs-485/ Serial pins are: USB port for "Serial" TX0 RX0 for "Serial0" TX1 RX1 for "Serial1" Z-Uno pinout.j...

Good job! Thanks a lot!

Hi kjetilhansen, AFAIK, Z-UNO is based on Sigma Designs ZM5101, which is 8051 architecture, while original Arduino is based on Atmel AVR. For a shame, standard SoftwareSerial library from arduino has a lot of AVR_specific binary code inside. Therefore, it's not portable. How about to use hardware se...

This shield looks great! I'm looking forward to buy one or two and fit them inside a DIN rail casing. Is the shield available already, please? Where can I order it? Idea: I'd like to have voltage divider for 10V ADC input, as 0-10V is the standard for many industrial sensors. But 12V divider can be ...

That's a great news, thanks a lot!

For a shame, adding another bridge is too complex for me.
A change in HW UART to support 2400 baud would be perfect for me, even if I had to buy a new HW version of Z-UNO.

Regarding Software Serial, I know that library from Arduino, but it's unportable, as it uses too much of ARK-specific code.

As for <9600, we will do it soon and release for public as there are many requests.

I'm looking for baudrate 2400 too. Is there a roadmap on this already?
Thanks!

Now it works
Z-UNO is sending a text and also able to receive info from RS232. Finally!

I've changed baudrate from 2400 to 9600 on both sides (sketch and Putty) and it started working.
Shame, I need 2400 baud as UPS has fixed baudrate

- Swapped Z-UNO board for a new one. - Swapped RS232 module for 2nd. - Probing RX/TX pins with a LED+resistor. LED slightly changes brightnes in both cases: 1) when I'm sending a string from Z-UNO, and probing TX pin 7 2) when I'm typing into Putty, and probing RX pin 8 So, the TX pin is able to sen...

For this particular model, there are just 3 pins in the supplied cable: - TX - RX - GND So, there's no need for hardware signalling CTS etc... :) Just checked Z-UNO, and RX/TX pins of UART0 are fried. But RX/TX pins of UART1 are still working in digital_out mode (LOW/HIGH). So, I will connect the RS...
