ATTACH THE POWER/DATA CABLE TO THE SCAN HEAD
With power off, use the power/data cable to connect the MOVIA scan head to the
system controller and ±15 V power supply. It is recommended that the power
supply voltages are verified before connecting the cable to the head to avoid any
damage.
The usage of cable channels and pin assignments are described in Table 1 and
Table 2.
