Ray,

 

    I have been away from the APCC for quite a while. Please remind me

- Does the APCC  firmware itself, check whether it is communicating with a CP3, CP4, or CP5 – and handles the “software mode” Limits & Meridian switch points,  itself? Or, does the user have to make  sure the controller is “user configured” in the APCC, as is done for the Keypad?

    I assume it is  automated, to avoid confusion and possible improper mount behaviour.

Hi Alex,

Are the collision zones you mentioned in counterweight-up or counterweight-down position?

APCC's Meridian Tracking Limits feature is designed to stop *tracking* at an hour angle limit and define mount flip points. If your 1100 has a CP4 its firmware handles counterweight-up slews in a "safe" manner by always moving RA first to a counterweight-down position, then slewing to a target. Additionally, if the target is counterweight-up, then the last slew will be in RA only also. (If your mount has a CP3 controller, then APCC performs these moves instead of the mount firmware.)
