Signal Connections
All portable instruments allow dual-access analog input signal connections. Connect your input signals to the
sheathed banana jacks or to the screw terminals. Digital inputs and outputs are accessible from the 37-pin AUXIL-
IARY PORT connector on DI-500-16, DI-750-16, DI-510-48 and DI-760-48 instruments only.
All desktop and rack-mounted instruments support screw terminal input signal connections only (no sheathed
banana jacks).
