SC929 线缆连接数据采集器和电脑,一端连接数据采集器的CSI/O接口,另一端直接连接电脑的9针端口。SC929 不带光电隔离,所以其只能用于电池供电的笔记本电脑(不连接交流电源)。
The SC929 cable connects the data logger'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 data logger 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 data logger over CS I/O utilize Modem Enable mode (ComME). It does not provide Synchronous Device Communication (SDC).
