"It seems RS232 connection will result in communication error when trying to read the data according to  Kickstart, but setting seems working"
--> RS-232 has never been supported. GPIB is the proper communication pathway to use with KickStart for this instrument.

The Data Logger app requires the instrument to have at least one scanner card installed.
The Data Logger will then make use of all scannable channels.

The DMM app does not require a scanner card. It uses the front or rear terminals to measure.

DMM & Data Logger licenses are as follows:
KICKSTARTFL-DMM-AN :  KickStart Precision Digital Multimeter Application Software; 1 year Subscription Floating License Option
KICKSTARTFL-DL-AN      : KickStart Data Logger Application Software; 1 year Subscription Floating License Option

For a complete list of KickStart licenses, look for the datasheet on the KickStart page:
