LAMBDA 10-3 OPERATION MANUAL – REV. 3.03 (20110829)
113
Encoding filter wheel commands into a single byte:
Command byte = (
wheel
* 128) + (
speed
* 16) +
position
Where
wheel
= 0 (Wheel A or C) or 1 (Wheel B),
speed
= 0 through 7, and
position
= 0 through 9.
NOTE: Wheel C is differentiated from Wheel A by having its command byte preceded
by the “Wheel C First Byte” command (252 decimal (FC hexadecimal)).
Table F-5. Status command return codes and data.
