and

change the value.

Setting the time and date is only required if

time synchronisation with GPS is disabled.

However the time zone and date needs to be

set for Nexus DSC to show the local time

correctly.

The easiest way to set the time and date

is to set the date and time zone and then

step outside to allow the GPS receiver to get a

fix and thus synchronise time from GPS.

It usually takes 30 to 60 seconds for the

GPS receiver to get a fix on the location

(under open sky conditions). Nexus DSC will

update the internal real time clock with the

time received by the GPS receiver at this time.

The GPS receiver will automatically be

switched into a power saving mode after it

acquired the location to conserve the battery

power.

Connecting to your telescope

Please plug the encoder cable into 'Encoders'

port on Nexus DSC.

To make sure that encoders are functioning

correctly Nexus DSC has a test mode.

Selecting 'Test' from the main menu activates

Then selecting 'Encoders':

angles:

In order for Nexus DSC to function correctly it

is required to adjust the encoder steps now to

make sure that:

• the RA/AZ current position in degrees is

increasing when rotating the telescope

clockwise around RA/AZ axis

• the Dec/Alt current position in degrees is

increasing when moving the telescope up

in declination/altitude

If either of those values is not increasing then

set the encoder steps for that axis to 'Reverse'

in the Telescope Settings.

Telescope Settings

Nexus DSC needs the mount type and

encoder steps to be set correctly before it can

be used to locate celestial object precisely.

The mount type and encoder steps are set in

the Telescope Settings that can be accessed

by selecting 'Setting' from the main menu:

then by selecting 'Telescope':
