RS232 Monitor/Control Cable (Half-Duplex)

This machine-made half-duplex RS232 monitor/control cable allows you to monitor RS232 data communication one direction at a time. It comes with a 6.6 ft (2 m) long straight-through cable for debugging (when used together with the optional Null-Modem converter - a unique and handy tool, it becomes a Null-Modem crossover cable), joint with a 3.3 ft (1 m) long monitoring cable.

NOTE: One COM port is required (Use the USB-232-1 to add a COM port to your PC if there is no COM port available).
