*For iXU-RS/iXU-R/iXU cameras, this connection is
mandatory.
The connection is not necessary for iXA-R/iXA cameras.
VIL — maximum voltage level that is interpreted as a ‘0’ by a input.
VIH — minimum voltage level that is interpreted as a ‘1’ by a input.
VOL — guaranteed maximum voltage level that appears on
output set to ‘0’.
VOH — guaranteed minimum voltage level that appears on
output set to ‘1’.
VIT+ — input threshold voltage when the input voltage is rising.
VIT– — input threshold voltage when the input voltage is falling
