GENERAL
MATRIX CONFIGURATION: 6 rows × 8 columns.
CONTACT CONFIGURATION: 2 pole Form A.
FIRMWARE: Specified for Model 2700 rev. B03, Model 2701 rev. A01, and Model 2750
rev. A01 or higher.

CAPABILITIES
DMM CONNECTION:
2-Wire Functions
Row 1, channels 1–8, through channel 50.
4-Wire Functions
Row 1, channels 1–4 (Source) through channel 50 and Row 2, channels 13–16
(Sense), through channel 49.
CLOSE CHANNEL: CLOSE command connects channels 1–8 to DMM. For 4-wire,
channels 1–4 are automatically paired with channels 13–16. ROUTe:MULTiple
allows any combination of rows and columns to be connected at the same time.
