Resumen
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.

This cable will work with the addition of an SC32B (pn 17229) to communicate with a CR10. A storage module connected to the CS I/O port with an SC32B will only be affected while there is communication via the SC32B. After communication via the SC32B is finished, the datalogger will be able to communicate with the storage module. Any data to be sent to the storage module will be held by the datalogger until the SC32B communication is finished.

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.

Hay dos opciones:
- Utilizar nuestro cable/interface SC-USB
- Utilizar un adaptador USB/RS232 disponible en el mercado informático. Pero cuidado que no todos funcionan adecuadamente. Consúltenos.

Many of our more recent dataloggers 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 dataloggers 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 dataloggers that don’t have an RS-232 port but have a CSI/O port:
- Use the SC-USB connector/interface instead of the SC32B.
- Use the SC32B with a 17394, USB-to-9-pin male RS-232 cable.
- Use a user-supplied USB interface with the SC32B.
For dataloggers 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.

Communication through the datalogger’s CS I/O port requires an interface that converts the computer’s RS-232 voltage levels to the CMOS levels of the datalogger. Typically, that interface is an SC32B. The SC32B connects to the datalogger’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.
-
Some possible causes include the following:
- The result of a hardware condition in the datalogger or the port driver
- Incorrect USB drivers (Even if the correct drivers have been successfully installed, the errors may still be related to the cable.)
- Note: Not all USB-to-serial cables are the same. 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. Cables that are not purchased from Campbell Scientific have not been tested and may result in errors when connecting to a datalogger. Furthermore, USB-to-serial cables with the FTDI chipset are easier to use and seem to perform better than cables with the Prolific chipset.
- Power supply or grounding issues on the datalogger
- The port configuration of the datalogger (If the datalogger RS-232 port is configured at a fixed baud rate other than 115200, it might cause the error messages.)
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 datalogger and will attempt to do so at various baud rates. If the datalogger 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.
