NOTE
1 The plus (+) sign of IiH/IiL represents the direction of flow
into the receiver. The minus (–) sign of IiH/IiL represents the
direction of flow out of the receiver.
2 The high–speed skip signal is assumed to be 1 when the
input voltage is at the low level and 0 when it is at the high
level.
3 The input level for the CNC receiver is high when the circuit
is open. So, the input level for the external driver must be
low.
