• KI_RPM_CV_2W or 1: Selects 2-wire CVU (4210-CVU)
• KI_RPM_CV_4W or 2: Selects 4-wire CVU (4210-CVU)
•
KI_RPM_SMU or 3: Selects SMU (4200-SMU)

Details
The 4225-RPM includes input connections for the 4210-CVU and 4200-SMU. Use this command to
control switching inside the RPM to connect the PMU, CVU, or SMU to the output.
When using the PMU with the RPM, rpm_config must be called to connect the pulse source to the
RPM output. Note that if there is no RPM connected to the PMU channel, the rpm_config command
will not cause an error. The RPM connection is cleared by the clrcon command.
Example
rpm_config(PMU1, 1, KI_RPM_PATHWAY, KI_RPM_PULSE);
This example sets channel 1 of the RPM for pulsing.
