Connecting Rotary Encoders
This camera can generate trigger signals or detect the scanning direction of the subject in
response to signals output from the rotary encoder.
■ Adjustment procedure
1
Input the two signals (phase A and phase B) from the rotary encoder.
Select which I/O on the camera (Line5:OptIn1, Line4:TTLIn1, Line10:TTLIn2,
Line13:TTLIn3) you want to input each of the two outputs from the rotary encoder
[phase A (Encoder Source A), phase B (Encoder Source B)].
2
Specify the number of triggers (number of vertical lines) to generate during
each rotation of the rotary encoder.
When [Encoder Divider] is set to [N], the rotary encoder generates 65536/N triggers.
When N is an integer multiple of 65536
Camera internal trigger is generated by decimation of output trigger of rotary
encoder.
When N is not an integer multiple of 65536
Using the time interval of the output trigger of the rotary encoder, Camera internal
trigger is generated so that the set division ratio is obtained.
Note
If the time interval of the output of the rotary encoder fluctuates greatly, the output
of the camera internal trigger generated may also fluctuate greatly.
In this case, by setting [EncoderAveragingInterval], it is possible to perform internal
processing with the value obtained by averaging the time intervals of the specified
number of signals.

If necessary, specify the strobe length of the generated signal.
When [EncoderStrobe] is set to [M], the strobe length will be [M]×10 ns.
3
If necessary, enable the low-pass filter for the signal to prevent unintended
operations due to signal noise from the rotary encoder.
Specify the number of cycles from a range of 0 to 15 (0 to 150 ns).
