Duet 3 UART

dc42

for the IO1 Connections, Does RX Terminate to Duet3 IO1 Out and TX Terminate to Duet3 IO1 IN?
Ground and Voltage is Easy.

The other way round. Tx (which you must connect to Rx on your other device) is on IO_1_OUT, and Rx (which you must connect to Tx on your other device) is IO_1_IN. Logical, because Rx is an input and Tx is an output.

I setup the Board In the Config File with M575 P2 S2 B9600 (Baud rate is 9600 on this Item)

Im trying to Send Commands to this Board Using M118 P5 S"XXXXXX" and I get an "Error: M118: Invalid message type: 5"

But in the Reference it Mentions #5

M118: Send Message to Specific Target
Supported in RepRapFirmware 1.21 and later.

Parameters

Pnnn Message type (0 = Generic [default], 1 = USB, 2 = PanelDue/UART, 3 = HTTP, 4 = Telnet, 5 = second UART) (optional)

@Toastinator said in Duet 3 UART:

"Error: M118: Invalid message type: 5"

is the duet's firmware up to date? (run M115 to verify)

dc42

Support for the second UART is not yet on released firmware. It will be in 3.2beta1 which is imminent.

albertshao

@dc42 which version have second uart, 3.2.2? or 3.3?

dc42

@albertshao 3.4.0 is the current supported firmware version.

@dc42 I test with my duet2 wifi board.
M575 P2 B57600 and reply "Error: M575: parameter 'P' too high".
Where do I miss ?

@albertshao I believe it's duet 3 only

albertshao

@jay_s_uk thanks

@albertshao that's correct, Duet 2 boards have only one externally-visible UART port.
