I’m replacing an old, analogue focus, zoom, pan and tilt head system to operate fairly large cameras and I’m loving the JRK for it’s size and versatility.
However, this is on a bench. In real life it will mostly operate a camera 6m (20ft) from the operator but occasionally needs to operate 30m (90ft).
This presents me with two options. 1) Keep the controllers close to me so I can programme it easily but have a long run of cable to the motor with an equally long run back for the analog feedback. 2) Have the controllers near the motors, be unable to program on the fly and have long runs of analog control.
Are there any issues with long cables and PWM?
It seems the ideal situation is to cut the JRK in two and have the input half, with its joystick calibration, 12 bit input and other benefits close to me, and the output half near to the motors!!
Can anyone with more experience than me cast a fresh mind on my dilemma. Incidentally, I would dearly love to make this into a radio system later, but for now…
Many thanks for reading.
