Hi,
I am now trying to have my master motor (SM34165DT) to send basic orders (change variable values) in a programmable stepper motor driver (LAM Technologies) using RS485.
I set up same parameters in both devices. Stepper driver is running with Modbus RTU Protocol.
If compatible, how should I send messages (in data mode or command, which synthax...)?
Exemple: Driver Adress: 10
Adress of word to modify: 0xA002
Thanks

The SmartMotors are only capable of acting as Modbus slaves. If you want to send the data as ASCII characters over RS485, see the OCHN command.
Did you restart it?
