5. At the prompt, enter 1 and press Enter to select the DMH (datahub) option.
6. Follow the remaining prompts, and press Enter after each response you type.
7. Once the installation has completed, type $KIBIN/shutdown_S530.pl and press Enter to
power down the S530 system.
8. Power up the entire system.
9. Log on as kthmgr.
To upgrade systems with KTE version 5.5.0 and later:
1. Open a new Linux
®
terminal session.
2. Type licCheck and press Enter to check if the datahub license is installed correctly.

3. If it is not installed correctly, you will need to edit the file at opt/kiS530/.ki_setup.
4. Go to line 33 in the file and change it to setenv COMPUTERNAME q1234 (where 1234 is your
QMO number).
5. Go to line 61 in the file and change it to setenv KI_QMO 1234 (where 1234 is your QMO
number).
6. Reboot the computer to reinitialize the datahub.
LO patch panel
The S530 must have a single, direct connection between instrument lows and protective earth (safety
ground). Keithley recommends that a high-quality, low-impedance connection between low and
protective earth (safety ground) be made at the prober used with the S530. Because this is not
always possible, the LO patch panel provides alternative connections. The LO patch panel provides:
A common reference point for all the instrument low-side connections
In 4-wire systems, a common connection for the sense low terminals of the source-measure units
(SMUs)
Connections from low to sense low using a 100 kΩ resistor to enable autosensing
Different ways to tie low to protective earth (safety ground)
The LO patch panel is configured by the Keithley Field Service Engineer (FSE).
