of the pier. Once the desired slew limit position is determined, click the

Reset Software Slew Limit (Hours Beyond Meridian)
Use this group of controls to configure the mount’s software slew limit hour angle. For example, when a
GEM is tracking near the meridian, at what hour angle should tracking be halted to prevent the possible
collisions or equipment damage? Additionally, when commanded to slew from
TheSkyX Professional
Edition
, should the OTA switch sides of the pier when the destination of a target object is on the opposite
side of the meridian? See “Hour Angle” on page 18 for more information about this topic.
Hours Beyond Meridian Pop Up Menu
The combination text box and pop-up menu, immediately to the left of the
Set To This Value
button, can
be used to either manually enter the “hour angle hours” for the software slew limit, or to choose from
one of the default values in the list. Click the
Set To This Value
button to permanently save this setting to
the control system’s firmware.
The table below shows lists Paramount model specific maximum hour angle. The Paramount ME II has
configurable “hard stop positions” (page 90) and the maximum hour angle depends on the position of the
