The 17394 is a six-foot interface cable fitted with a USB connector on one end and a 9-pin 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.

The 17394 is compatible with any device that has an RS-232 port. It can also connect to the data logger's CS I/O port via the SC32B interface, and connect to some peripherals via the SC532A interface.
This driver is for the CB-FTDI USB to Serial cable (CSI Part# 17394 - Black Cable). Support is for Windows XP/Vista/7/8/10/11 32 & 64 bit. This driver is not compatible with the SC-USB Interface.
Note: Install the driver before plugging the cable into your computer. Once the driver has been installed, plug the cable into the computer to finish the installation.
This driver is for the SBT-USC6K USB to Serial cable (CSI Part# 17394 - Silver Cable). Support is for Windows XP/Vista/7. This driver is not compatible with Windows 8 and above or the SC-USB Interface.
Note: Install the driver before plugging the cable into your computer. Once the driver has been installed, plug the cable into the computer to finish the installation.

A USB-to-serial cable has electronic components in it to interface the USB to the RS-232. There is no pin correlation between USB and DB9.
The combination of the USB to serial (17394) and the SC32B is basically the same as the SC-USB. Both options enable communication between a computer and a data logger with a CS I/O port.

Many of our more recent data loggers have a Micro B USB port. Simply use a Type A to Micro B, male-to-male cable. Although any USB cable, with the correct connectors and drivers, should work, there is a better chance of success using a cable supplied by Campbell Scientific.
For data loggers with an RS-232 port, only a serial or USB to RS-232 cable (sometimes called a USB-to-serial-adapter cable) is needed. Although any USB to RS-232 cable should work with the appropriate drivers, there is a better chance of success using the USB to RS-232 cables sold by Campbell Scientific.
There are several options for data loggers that don’t have an RS-232 port but have a CSI/O port:
For data loggers with a CSI/O and RS-232 or USB port, it is not necessary to use the SC32B unless there is another device connected to the RS-232 port or there are concerns about low-level noise from a permanently connected, ac-powered computer.
Some possible causes include the following:
The Device Configuration Utility, under its Unknown device type, has an Identify Logger Type button. This button will attempt to identify the device type, protocol, or both used for the data logger and will attempt to do so at various baud rates. If the data logger is synchronized with a different baud rate or is set up at a fixed baud rate, this feature may provide the means of determining what baud rate should be used for successful communication.
Communication through the data logger’s CS I/O port requires an interface that converts the computer’s RS-232 voltage levels to the CMOS levels of the data logger. Typically, that interface is an SC32B. The SC32B connects to the data logger’s CS I/O port via an SC12 or serial cable and connects to a computer’s 9-pin serial port via a serial cable. When the computer does not have a serial port, a 9-pin serial-to-USB cable, such as pn 17394, can be used with the SC32B. Alternatively, instead of the SC32B, use the SC-USB.
