tility Functions

Utility Functions are useful tools that provide simple, one-step processes to your SynScan

TM

 AZ.

Show  Position 

-  This  displays  the  coordinates  of  the  location  where  the  telescope  is 

currently pointed. The coordinates can be displayed in Dec and RA, Alt and Azm, or Ax1 (the 

angular reading of the elevation) and Ax2 (the azimuth axes of the mount). Use the scroll 

keys to choose your desired reading.

Show  Information  - 

Under  this  submenu,  you  may  check  local  time,  local  sidereal  time, 

hardware, firmware and database version of the SynScan hand control. If the hand control is 

connected to the mount, this menu will also display the firmware of motor control board.

Park Scope

  - The  Park  Scope  function  is  useful  when  you  prefer  to  have  the  telescope 

start  from  a  certain  position  for  your  next  observing  session.  No  star  alignment  will  be 

required  in  your  next  observing  session  as  long  as  the  telescope  has  not  been  moved. 

There are three options to park your telescope:

PAE

 - Pointing Accuracy Enhancement. See page 13 for information.

Clear PAE data

 – This function clears all PAE data stored in the hand control.

GPS

 – This allows you to obtain information from the optional SynScan

TM

 GPS receiver. 

PC  Direct  Mode

  – The  PC  Direct  Mode  is  used  for  updating  the  firmware  of  the  motor 

control board. It allows direct communication between the computer and the motor control 

board of the mount. 

Time

 - This displays the local time and the local sidereal time.

Version

 - This displays the hardware, firmware and database version of the SynScan

TM 

AZ 

hand control. This menu also displays the firmware version of the motor control board, if 

the hand control is connected to the mount. Use the scroll keys to scroll up or down to 

view the version numbers.

Temperature

  –  This  displays  the  temperature  detected  from  the  thermal  sensor  in  the 

hand control in both Celsius and Fahrenheit.

Power Voltage

 – This displays the power voltage detected from hand control in Volts.

HOME 

position - This is the position where both Ax1 and Ax2 reads 0. If you have done 

the  star  alignment  for  GoTo  operation  or  followed  the  initial  setup  for  autotracking 

operation,  the  HOME  position  of  your  telescope  should  be  North  facing  and  the  tube 

parallel to the ground.

CURRENT 

position - This is the position where the telescope is currently pointed.

CUSTOM 

position  -  This  is  the  position  where  the  telescope  was  previously  parked 

before the power was last turned off. This option is useful when you prefer to always start 

the telescope from a certain position other than the HOME position.

S

etup Functions

Daylight Savings

 - Allows you to change the Daylight Savings option. 

Alignment

 - Allows you to perform the star alignment.

Alignment Stars

 -   

The Setup functions allow you to change any system variable or information regarding location, 

time, date, and alignment configurations. To access the Setup Functions, either press 

SETUP

 key 

on  the  key  pad  or  scroll  to 

SETUP

  under  menu  option  using  the  scroll  keys.  Below  lists  the 

different types of functions available to you, and their purposes.

Date

 - Allows you to change the date entered at the initial setup. 

Time

 - Allows you to change the current time. 

Observing site

 - Allows you to change the current location. 

Auto  Select  -  When  this  option  is  chosen,  the  hand  control  will  filter  out  the  star  not 

suitable for star alignment.

Sort  by  - This  allows  the  hand  control  to  generate  a  list  of  alignment  stars  and  display 

them alphabetically or by their magnitude.  

Backlash

  - This feature allows you to insert a value for each axis to compensate for its backlash. 

For better pointing accuracy, it is important that the backlash value is set to be equal or greater than 

the real amount of backlash between the gears. The default setting of the backlash is 0 d 00' 00" (0 

degree, 0 arcmin. and 0 arcsec.). Use the numeric keys to enter the desired value and press the
