Hi there, I am working with a large number of the Keithley 2231A-30-3. I would like to communicate with it VIA PC but Tek, states you must use the Keithley USB adapter ($$$) I have found the pin-out of the propriety connector (2=rx,3=tX). Has any one been able to get this power supply to communicate to their pc? ( may only respond to read only commands) Thanks. |

So I connected a FTDI TTL adapter tx/rx and tried with EEZ studio to get a response for a *IDN? command. I cant get a response in the software but i can see that both Tx/Rx lights illuminate. (there is a response of some kind.) Any ideas where the issue could be? I will try with "Test controller" software. |

Did you try different baud rates / flow control / parity / stop bit configurations? If it outputs anything on power on, you could capture that with a scope or logic analyzer and check the repetition rate and count the number of bits. |

I will try and scope the RX Line. |

was you been able to communicate with the device ? It uses 3.3V level RS232 signals at 9600 baud. I found it to be very slow for the measurements of the output Voltage and Current (300+ ms per query) Have you come around this problem ? Benno |
