If the Jrk is connected to your PC via USB, you will need to set the JrkРІР‚в„ўs serial mode to РІР‚СљUSB dual portРІР‚Сњ in the РІР‚СљInputРІР‚Сњ tab of the Jrk G2 Configuration Utility. Also, you might need to change the line that sets port_name in order to specify the correct serial port. The JrkРІР‚в„ўs input mode should be set to РІР‚СљSerial / I2C / USBРІР‚Сњ, or else the РІР‚СљSet targetРІР‚Сњ command will not work.

Python read serial input how to#

It demonstrates how to set the target of the Jrk by sending a РІР‚СљSet targetРІР‚Сњ command and how to read variables using a РІР‚СљGet variablesРІР‚Сњ command.

pyserial module encapsulates python's access to serial ports, providing a unified interface for the use of multiple platforms. Serial port is a very general equipment communication protocol on computer. This communication mode uses fewer data lines and can save communication cost in long distance communication, but its transmission speed is lower than that of parallel transmission. Serial communication is a kind of communication mode between peripherals and computers, which transmits data bit by bit through data signal lines, ground lines, control lines, etc.
