All Keithley Instruments that use serial (RS232) require a straight-thru cable.
Secondly because this is an IVI driver it is using VISA and VISA (by default) requires that the instrument send a linefeed at the end of any data it sends back so you need to select on the instrument line feed (LF) and NOT CR or CR + LF. This setting is after the baud rate and flow control and call "Tx Term".

Thanks for your suggestions everyone, they are very much appreciated!
Developments since I got the correct cable:
MAX: I can write *IDN?\n and then it reads and outputs "KEITHLEY INSTRUMENTS (etc.)" so there is some communication there. However I still also receive the BFFF0015 timeout error. The communication is also showed by the fact that when I execute the 'write' command the front display of the picoammeter goes into remote operation mode.
LabVIEW Instrument I/O assistant: When I 'Query and Parse' I still get the timeout error and error 113 (undefined header) is displayed on the front of the picoammeter
