Front I/O Characteristics

Note The 32 front I/O channels are organized into two banks consisting of two ports with eight channels per port. Port0 and Port1 are in Bank0; Port2 and Port3 are in Bank1. At least one Vsup must be present and routed to the banks. Each bank can be powered by either Vsup_0 or Vsup_1.
Note The mapping between the 32 rear I/O channels and the 32 front I/O channels is one-to-one. DIO0 maps to P0.0, and DIO31 maps to P3.7.

Caution Do not connect the SLSC-12201 to signals or use for measurements within Measurement Categories II, III, or IV.
Attention Ne connectez pas le SLSC-12201 à des signaux et ne l'utilisez pas pour effectuer des mesures dans les catégories de mesure II, III ou IV.

Measurement Category I is for measurements performed on circuits not directly connected to the electrical distribution system referred to as MAINS voltage. MAINS is a hazardous live electrical supply system that powers equipment. This category is for measurements of voltages from specially protected secondary circuits. Such voltage measurements include signal levels, special equipment, limited-energy parts of equipment, circuits powered by regulated low-voltage sources, and electronics.

Note Measurement Categories CAT I and CAT O are equivalent. These test and measurement circuits are for other circuits not intended for direct connection to the MAINS building installations of Measurement Categories CAT II, CAT III, or CAT IV.
