Connecting Rotary Encoders

Related Setting Items:
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 (EncoderSourceA), phase B
(EncoderSourceB).
2. Specify the number of triggers (number of vertical lines) to generate during each rotation of
the rotary encoder. When EncoderDivider is set to N, the rotary encoder generates
65536/N triggers.
When N is an integer multiple of 65536: The camera's internal trigger is generated by
l
the decimation of the output trigger of a rotary encoder.
When N is not an integer multiple of 65536: Using the time interval of the output trigger
l
of the rotary encoder, the camera's 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.
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) in EncoderFilter.
4. If necessary, specify the strobe length of the generated signal. When EncoderStrobe is set
to M, the strobe length will be M×10 ns.
