4 Electrical Interface
P1 and P2 Connector Terminals
Table 3, Table 4 on page 5, and Table 5 on page 5 show the pinout of the P1
and P2 connector terminals for the Neuron 3150 Control Modules. The I/O pin
function names defined in Table 3 are the same as those used in the Neuron
Chip Data Book, which defines the functions and electrical characteristics for the
signal names. The I/O signals are connected directly to the Neuron 3150 Chip
without buffering.
