Digital I/O
The 44-pin Digital I/O port on the IC-317x offers 8 isolated inputs, 8 isolated outputs, 2
bidirectional differential inputs (RS-422) or single-ended input lines that can be used with a
quadrature encoder, and 8 bidirectional TTL lines. The Digital I/O port can be connected to
any appropriate shielded device or connector block using a shielded cable.
NI recommends the following digital I/O cables for the IC-317x.
