For the command Position Write (PW) it states that the minimum is 0 and the maximum RR (which is logical). However, the provided example is @PWR,-1000 which should not be issued as -1000 is not in range.
Moreover, Position Read (PR) gets the current position as a signed integer. However, since position should always be in [0, RR] it has no sense that the value is signed.
I'm checking the firmware protocol (I assumme is version 4.0.0): https://github.com/nexdome/ASCOM/wiki/Firmware-Protocol
