Figure 37: Rescaler
If the rescaler is enabled, the external line frequency will be modified using the Trigger
Multiplier and Trigger Divider commands, as shown above. For details, please refer to the
Rescaler section in the GURU section.
Note: the Trigger Multiplier takes the following three values only:
0 = frequency x 256
1 = frequency x 16
2 = frequency x 4096
For more information about the Rescaler, please refer to Rescaler in the GURU section.
External Line Trigger, External Direction Control from Rotary
Encoder
Physically connect rotary Encoder phase A to pin1-5 if using TTL, or pin 1-2 if using LVDS,
and phase B to pin 6-5 if using TTL, or pin6-7 if using LVDS.
In the Line Trigger Function Group > Set the Line Trigger Mode value to On.
Set Rotary Encoder Module to True.
