不能和我的串行仪器通信 我正在和我的串行仪器通信。 在 HyperTerminal 输入指令时, 该装置正确地产生了回应。 但当我在 LabVIEW 输入相同的指令时, 我会得到不正确的回应或是 timeout。为什么我的装置可以在 HyperTerminal 使用, 却不能在 LabVIEW 使用? 即使我用 'LabVIEW Serial' 的范例也不能行 URL: http://digital.ni.com/public.nsf/allkb/8224EC54DF27BBB5482572270013B0BE
Preventing LabVIEW from Continuously Polling the Serial Port When I read from my serial port, LabVIEW continuously polls for data until the data is available on the port. This increases my processor and resource usage and prevents other loops in my program from executing smoothly. How can I prevent this?

병렬 포트의 출력 전압은 무엇입니까? 문제점: 병렬 포트의 출력 전압은 무엇입니까? 솔루션: 대부분의 새로운 병렬 포트는 TTL 레벨을 사용합니다. TTL 표준은 로직이 하이(HIGH)일 때, 2.4V에서 5V사이를 인정합니다. URL: http://digital.ni.com/public.nsf/allkb/591D115D70D44A7586256F5C00819651
How Do I Write Control Characters to a Serial Port? I need to send a string to a serial device that includes a control character such as "Ctrl+B", but LabVIEW will not display anything in the write buffer when I enter Ctrl+B on the keyboard.
