MOVIA, 2-Axis Scan Head – User Manual, 1040–0004 Rev. 03
12
Channels
Behavior
X Y Z DATA
The vector controller used to drive the scan head will deliver
set values for X, Y and the optional Z axis.
The X, Y, and Z Data are three 20-bit serial data streams that
consist of one 3-bit control code, one 16-bit position word
(unsigned, MSB first), and an even parity bit.
Improper control codes, parity error, or a missing sync on
the 21
st
clock cycle will cause the position data word for the
affected channel to be discarded. 001 is the only supported
control code.
GROUND AND
VOLTAGE
The ground and voltage channels provide power to the scan
head.
