Datenkabel / SC929
SC929 9-Pin-auf-9-Pin CSI/O auf RS-232 Kabel

Überblick

Das SC929  ist ein Interfacekabel zwischen Datenlogger und Computer. Damit wird der CS I/O-Port des Loggers mit dem seriellen RS232-Port des Compters verbunden. Das SC929 bietet keine optische Isolierung und sollte deshalb nur mit Notebooks oder Labtops verwendet werden, die mit internen Akkus laufen (keine Verbindung zum Stromnetz).

Technische Beschreibung

The SC929 cable connects the datalogger's CS I/O port directly to the 9-pin serial port of a battery-operated laptop. It converts the CMOS logic levels of the datalogger to the RS-232 logic levels of the laptop. The SC929 does not provide electrical isolation, so it should only be used with laptop computers running from internal batteries (not connected to ac power).

Communications with a datalogger over CS I/O utilize Modem Enable mode (ComME). It does not provide Synchronous Device Communication (SDC).

  1. Can an SC929 be used to connect a datalogger CS I/O terminal with a sensor that has an RS-232 output?

    Yes.

  2. How do the SC929 and SC32B compare?

    The SC929 has been functionally replaced by the SC32B. While the SC929 is still available, the SC32B has increased capability at a reduced cost. See the table for a comparison:

    Cables are an additional comparison point for these two products:

    • The SC929 cable directly connects the PC to the data logger’s CS I/O port.
    • The SC32B interface typically uses the 10873 serial cable to connect to the PC and the SC12 cable to connect to the CS I/O port. Both of these cables are shipped with the SC32B.
  3. How do the 17934, the SC32B, the SC929, and the SC-USB compare?
