Serial port interface uses Max3232 device

What a pitty - I hoped to be able to connect th microcontroller directly ;-)

Good morning!

During weekend I figured out how to deal with the serial interface. I got it enabled and could decode the cylic output with my osciloscope as described by ytilu. BUT: The voltage range of TRX is from 0.0V to 1.5V relative to GND, not as expected from -12V to 12V. I don't think, this is normal, is it?

Interesting info, hope to try it soon.

One of examples - periodical sending of current coordinates to external serial device. E.g. to scan heights on reference points, etc.
So If I'd like to send current coordinates of X (just for example, purely for education needs) via current scheme ("signal bits") following information could be helpfull:
1. Are there bitwise operators being supported by the G-code intepreter? AND or XOR for example. I know Fanuc supports them, does DDCSV supports them too?
2. Ability to apply bitwise operator to the contents of the macro variable containing coordinate piece?
3. Bit format of the internal coordinate representation. Though it could be reverse engineered if it's possible to apply bitwise operator to the macro variable ;)
4. Frequency of packet sending
5. Port parameters (baud rate, bit configuration)

If DDCSV have no control on packet sending I'll need to reserve some bits for status indication (e.g. packet ready/finished), so speed parameters are crucial here (as several packets are needed to send a single coordinate piece, and to send all three/four - it's even more time).

Hello 71taa

Currently DDCSV2.1 only supports simple serial protocol, and can not use macro program to control sending and receiving.
The DM500 Handheld CNC Motion Controller supports the MODBUS communication protocol, and the data transfer can be controlled by a macro program to meet your needs, you can try it.

Hi all!

Concerning the default value of the Serial Output when enabled with parameter #108:
The value for #109 in the eng (rus...) file is defined as

#109 -t0 -s1 "M Bus IO default status" -m7 -min=0 -max=4294967295

But it seems, that the t0 type input with integer numbers is only possible for 16 bit unsigned values so that the maximum value, which can be set when using the parameter setting page is 65535.
Changing to

#109 -t0 -s1 "M Bus IO default status" -m7 -min=0.000 -max=4294967295.000

does not realy help. To conclude: it is not possible to set the default values for the 3ed and 4th byte of the serial stream. Not so important, but may be changed in a future version.

BTW: The 0V..1.5V output peak for TRX was my fault. I exidently got the neighbouring cable and the values there did only exist caused by a cross-talk effekt ;-(

Hi!
How to recofigure M-code in DDCSV2.1 ?

I wish to change M-code for my own needs.

Hey good afternoon!

I have a DDCS 3.1 and I really need help because I can't configure the functions that my machine has.

When I click RESET on the command, I need it to trigger an external relay that releases the brake of a motor. When the motor goes into alarm, it must activate the RESET and necessarily deactivate the motor brake relay.

Is this possible configuring only the DDCS or is it possible to do this through a macro?

I also have a spindle turning function for 2 sides and the M3 works correctly in my inverter but the M4 does not... is it possible to configure the M8 to trigger an external relay that can turn my inverter the other way?

Thank you very much and I hope I can solve this problem
