did any one figure out how to connect a PC to its serial port ? nothing seems to work please tell me how you did it ? |

Hi, We got the ST2830 from Sourcetronic, which seems to be 1:1 the same. https://www.sourcetronic.com/shop/de/kompaktes-lcr-meter-st2830.html You can download usb driver, but the software isn“t for free. Maybe it will work with the one from member HKJ. Nevertheless, I could call the german support and ask them for the RS232 interface(not mentioned in the manual), would post the answer here. Martin |

I am only interested in the serial port, since my PC is too far away from the instrument for USB connections. a serial cable can easily be 10meters, but usb can not. RS232C in a DB9 connector should be a very simple industrial standard, some variations exist, so for clarify it could have been nice to see the pinout and handshake requirements explained in the user manual, i dont get any answers on *IDN? i am in 8n1 9600 baud and scpi mode i also tried the talk only mode, and still dont see any kind of data out, double checked with a scope. any kinds of help you maybe able to come up with, is much appreciated, |

Usb can if you have an usb cable repeater or extender, some have 15 feet in length ... or you can use usb to fiber converters an can go to higher distances ... |
