有關GPIB的ERR

請問我用labview控制一motech的power supply(pps1005),它是用gpib我用labview的measurment&automation要與儀器連線時卻發生

一些錯誤,它的信息是這樣的iberr = EABO

EABO indicates that an I/O operation has been canceled, usually due to a timeout condition after a GPIB read.  Before reading from the instrument, verify that the GPIB command you are sending is understood by your device and instructs it to place data in its output buffer.  For information on your device's command syntax, consult the instrument manufacturer's user documentation.

其中我的gpib都有抓到,我是用ni的gpib它對電腦是usb接頭,驅動程

式都裝了,而看它的意思是說我的機器的instruction打錯了,我是用

*IDN?這個指令,而且儀器的manual中說用來跟電腦做識別的也是用

這個指令,但不知為何會這樣?是我少裝了甚麼嗎?

其中measurement&automation中的device&interface裡面的

identification的value是the device did not respond to a *IDN?...

感覺上它好像真的不認這指令.為甚麼會這樣呢??

有高手可幫我解答嗎?謝謝!

這情形我遇過

茂迪的power supply 不支援一般GPIB指令

他有私立的COMMAND

請洽茂迪應用工程師索取該儀器之 GPIB PROGRAM MENUAL
