DE535脉冲延时发生器

[Asill]

在NI官网下载了DG535的驱动例程后，连接到仪器上后程序无法运行且在NI-MAX上的端口上检测不到设备。且在程序过程中程序报错。有大佬知道是哪里的问题吗？

After downloading the DG535 driver routine from the NI official website, the program cannot run after connecting to the instrument and the device cannot be detected on the port on NI-MAX. And the program reports an error during the program. Does anyone know what the problem is?

Try Can’t See GPIB Instrument Using Scan for Instruments In NI-MAX before running the LabVIEW code.

I tried, couldn't detect the device in the scan, and the connection was fine... But the DG535 can enter remote control mode. Another question is that the DG535 driver downloaded by NI official website is plug and play? We don't have to make any changes, do we?

The drivers downloaded from the NI Idnet page are in fact examples of using NI-VISA API.

As long as you cannot detect the instrument using NI MAX, which uses the same API, the plug-and-play example/driver won't work.

Try the steps in Unable to Communicate with GPIB Instrument as well.

Hi Asill, 

What do you mean by the DG535 can enter remote control mode?

I had a quick look at the manual, and there are two possible things you can look at:

1. Check that the GPIB address is set properly.
2. On Pg.17, under the section "GPIB problems", it is stated the instrument will respond to commands only if the REN (remote enable) line is asserted. In NI MAX, you can explore this setting "Assert REN when SC" for your USB GPIB. You can see this under the Advanced Settings. If it was not enabled, enable it and save, then try to scan for instrument again.

Regards,

Victor

Thank you. I'll try again

I'm sorry, my description is wrong. After I connected the instrument, the DG535 REN indicator light turned on, but the program didn't seem to work properly when I ran it
