The 17394 is a six-foot interface cable fitted with a USB connector on one end and a 9-pin male RS-232 connector on the other end. The USB connector attaches to the USB port of a PC. The RS-232 connector attaches to the RS-232 port of a data logger or peripheral, such as an MD485 Multidrop Modem or RF401-series Spread-Spectrum Radio. Alternatively, the RS-232 connector can attach to an SC32B interface, which attaches to the CS I/O port of a data logger via the SC12 cable.
