Chapter 1 Outlines of the HA -655 driver
- 6 -
1-7 Outlines of I/O ports
The CN2 connector provides input and output signals to and from a host device. The 50 pins of the
connector are assigned to the following signals in each of the [position mode] and the [speed mode].
(Notice: Do not connect signals to pins marked “-.)
