Hi,
We have an SR510 Lock-in amp in our lab that doesn't have a GPIB port. I am trying to communicate with it via its RS232 port but with a GPIB-USB-HS+ to the computer end. Therefore we've got a GPIB-RS232 converter in hope to work. So far it is not working at all.
Since I am using the converter just to convert I've set it at D mode. I cannot query its "*IDN?" with Max, neither "*IDN?\n" or "*IDN?\r" works. I've also tried it with G mode. query function only works when the converter was set at configuration mode but not at normal mode. I've made sure the switches at the back of the lock-in matches the setting during the configuration. At least to my best knowledge...
I'm at the end of my rope here. Anyone who knows how to set this GPIB-RS232 box so I can talk to the lock-in? Thank you so much in advance.
