17394 Converter, USB to DB9 Pin (Male) RS-232

Overview

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.

Expand AllCollapse All

  1. Can a USB-to-9-Pin Pin (Male) RS-232 Cable (pn 17394) be used between a laptop and a CR10 datalogger, which has a storage module (SM192)?

    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 data logger will be able to communicate with the storage module. Any data to be sent to the storage module will be held by the data logger until the SC32B communication is finished.

  2. What is the pin connection between USB and DB9 (RS-232) connectors?

    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.

  3. If a computer does not have a serial port, how can the SC32B be used to connect to the data logger?

    There are several options:

    1. Use the SC-USB connector/interface instead of the SC32B.
    2. Use the SC32B with a pn 17394, USB-to-9-Pin Male RS-232 Cable.
    3. Use a user-supplied USB interface with the SC32B.

    If the data logger being used has an RS-232 port, only a serial cable is needed. 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.
