the cameras only do one thing at once- movement zooming or whatever -
and they dont accept any new commands until the last one has finished-
so you cant do more than one thing at a time - and this is a camera thing -
it means you cant do smooth movements for example- this is how the cameras work - you cant use them as hot heads with live panning etc.
but the hysterisis in position repeatability is reasonable for a unit this size.
so you have to test to see if it does what you need to do-
there isnt any weird dmx/rs232 resolution loss- the integer number resolution is the same.
