1.b. Supported Operating Systems

The jrk works under Microsoft Windows 11, Windows 10, Windows 8, Windows 7, Windows Vista, Windows XP, Linux, and Mac OS X 10.7 or later.

The configuration utility works only in Windows, so the jrk must be initially configured from a Windows computer, but after that it can be controlled from a Linux or Mac computer.

Under Linux, the two virtual COM ports created by the jrk should appear as devices with names like /dev/ttyACM0 and /dev/ttyACM1 (the number depends on how many other ACM devices you have plugged in) and you can use any terminal program (such as screen) to send and receive bytes on those ports. Alternatively, you can use the Pololu USB Software Development Kit which supports Linux and has example applications that control the jrk using its native USB interface (see Section 6).

Under Mac OS X 10.7 or later, the two virtual COM ports created by the jrk should appear as devices with names like /dev/cu.usbmodem00034567 and you can use any terminal program (such as screen) to send and receive bytes on those ports.
