RS232 Monitor/Control Cable (Full-Duplex)

This machine-made full-duplex RS232 monitor/control cable allows you to monitor RS232 data and line states (CTS, RTS, DTR, DSR, DCD and RI) in two directions at the same 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 3.6 ft (1.1 m) and a 3 ft (0.9 m) long monitoring cables.

NOTE: Two COM ports are required (Use the USB-232A-1 to add 2 COM ports to your PC if there is no COM port available).
