XSY-AT1 VFD on/off and speed wiring enquiry

"someone knows how to use the rs 485 communication of this model of drives. and the language that is used if it is hexdecimal binary etc ..... a greeting"

Folks, for posterity (and hoping someone can help), here's some info on getting through to XSY-AT* VFD using Modbus ASCII protocol: https://www.chipmaker.ru/topic/21809...omment=4791765

I've written a little python program, but so far I've got only random garbage back (padded with lots of zeros) from the serial port, regardless of what command I send and baud rate used. The VFD works fine using panel controls.

# send the "jog" command
# ./send-cmd.py '3A 30 31 30 36 32 30 30 30 30 30 30 33 44 36 0D 0A'
ascii: 3A 30 31 30 36 32 30 30 30 30 30 30 33 44 36 0D 0A hex: bytearray(b':010620000003D6\r\n')

Hope someone has figured it out and can help..
