Aggiornamento della Pulsantiera SynScan

126. Inserisci il connettore del cavo di collegamento computer nella presa centrale RJ-11 sulla Pulsantiera. Collega l’altra estremità del cavo, il connettore DB9, nella porta RS-232 del tuo computer (se il tuo computer non ha la porta seriale, dovrai acquistare un convertitore USB-Seriale e installare i suoi driver).

127. Premi e mantieni premuti i tasti 0 e 8 simultaneamente, poi inserisci il cavo di alimentazione nella Pulsantiera.

128. La Pulsantiera emetterà un suono indicante il riuscito avvio e sul display si visualizzerà SynScan Update Ver. x.x.

129. Avvia il software SynScanFirmwareLoader. Una volta che il programma è avviato, dovresti vedere una finestra come questa:

Il pulsante HC.VERSION fornisce il numero di versione dell’hardware, del firmware e del database. È solo per un tuo riferimento.

130. Clicca BROWSE per selezionare il file SynScanVXXXXEQ.ssf, poi clicca UPDATE per iniziare la procedura di aggiornamento del firmware nel SynScan. Puoi controllare la percentuale di avanzamento sotto i pulsanti UPDATE e HC.VERSION.

131. Quando la procedura di aggiornamento è completa, comparirà Update Complete. SynScan è così aggiornato con il nuovo firmware. Generalmente questa procedura dura circa 30 secondi, ma se stai usando un convertitore USB-RS232 potrebbe volerci più tempo.

Note di rilascio SynScan Firmware

  1. GPS function added. The SynScan hand control automatically retrieves Longitude, Latitude, and Universal Time for initial setup when the SynScan GPS is in use.

  1. Criteria for alignment star selection implemented in the software. The star alignment list contains only the appropriate stars for the time, location, and star alignment method selected.

  1. Automatic backlash compensation when under PC control or slewing using directional keys.

  1. Adjustable beeper volume under SETUP menu -- HANDSET SETTING.

  1. PAE function accessible from the UTILITY menu.

  1. Temperature and Power Voltage display under UTILITY menu -- SHOW INFORMATION.

Bugs reported in the 3.01 firmware fixed.

3.11,  2007.01.17

  1. Firmware version and warning message displayed at power up, before the Initializing message.

  1. Daylight saving setup required throughout the year instead of just in summer.

  1. The hand control displays hour angle and clock position of Polaris after location, date and time are entered.

  1. Fix default backlash retrieving bug and set the default backlash as 0°02'00" when the hand control is powered up for the first time.

Fix bugs in PEC Training and PEC replaying.

3.12,  2007.03.13

  1. More options available for alignment star selection, Auto select or manual select, and alignment stars sorted by magnitude or alphabet. See "Alignment Stars" under submenu "SETUP".

  1. "Clear PAE data" added under "Utility".

  1. Three parking positions available:

  1. HOME +90 degrees (Northern Hemisphere) or -90 degrees (Southern Hemisphere) in DEC.

  1. Current Position Park the scope at currently position.

  1. Custom Position Slew and park the scope to the previously saved parking position.

To save a parking position, choose one of the above parking positions under Utility-Park Scope, then turn off thepower. (ESC to cancel and escape from the Utility menu.)

If there is a parking position stored in the system, SynScan will prompt "Start from park position?" at power up.

  1. IMPORTANT!! Re-enter the Time Zone data on your hand control after installing the V3.12 firmware.

3.20,  2007.11.16

In this new released firmware, we have improved the planet orbital calculation and fixed the inconsistent in Double Star and Variable Star Catalogs. You may directly update the SynScan firmware from V.3.10 to V.3.20. Please refer to our web site at

All the modifications are described as follows:

  1. The time zone setting has been changed to more precise in minutes for locations with half hour definition. For example, if you live in a region with -3.5 hours of time zone, the setting will be -03:30, indicating minus three hour and thirty minutes.

  1. The planets' orbital calculations have been enhanced based on "Keplerian Elements for Approximate Positions of the Major Planets", published by NASA Jet Propulsion Laboratory. The calculation data are available and reliable from 1800 AD to 2050 AD. Most of the calculation precision will be within one arc min and others such as Jupiter and Saturn will be within a few arc mins.

  1. The Identify function has been improved to be able to identify planets.

  1. The inconsistency in Double Star and Variable Star database while scrolling the list has been corrected.

  1. In the SETUP menu, we add a Factory Setting function under the SETUP menu. You may choose to reset the settings to the default settings. Restarting the mount (switching off the power and turning it back on) is required afterward. Note: All the settings of Longitude, Latitude, time zone, daylight saving, backlash, PEC data, PAE data and previous alignment data will be deleted, except for the user defined object coordinates.

Frequent visit to the Sky-Watcher web site to check for new released firmware is recommended. If you have any suggestion, bug report or support request, please forward it to us at "".

3.21,  2008.02.04

  1. Smoother response to manual guiding and PC based autoguiding command.

  1. "PC Direct Mode" added. It allolws the PC to communicate directly with the motor controller via RS-232C connection. The RS-232C port of the PC should be configed as 9600bps, 1 start bit,  8 data bits, 1 stop bit, no parity check and no flow control. Activate "PC Direct Mode" under "Utility\PC Direct Mode>". Press the "ESC" key to exit. The 4 direction buttons and rate controlling function operate as usual under this mode. This feature is also designed for future applications.

3.22,  2008.06.05

  1. Add SAO submenu in Object Catalog. The total number of objects in database increased to 42,900.

  1. Enhance Show Position function: display telescope current position by RA/Dec, AZ/ALT or motor drive readings of both axes.The data display is accurate to one arc seconds.

  1. Add precession compensation in coordinates calculation.

  1. Additional information such as the rise, transit and set time of an object is available when browsing the information for an object. If a selected catalogue object is currently below horizon, the hand control will prompt "Below horizon!" for two seconds to notify user.

  1. Improve "PC Direct Mode" function and fix the directional key lock out problem in "PC Direct Mode".

3.23,  2008.07.30

  1. Fix bugs existed in firmware version 3.22--Now tracking mode is deactivated automatically when the goto object selected is an user-defined alt-azimuth position.

  1. Fix bugs existed in firmware version 3.22--Now the hand control will not lock up when the user chooses to advance directly to the Show Position option, skipping the initial alignment procedure.

3.24,  2009.01.26

  1. Fix bugs in firmware version 3.23--now the hand control setting will remain upon power up, after the PAE function was performed.

  1. Improve LED and LCD backlight performance.

3.25,  2009.06.24

  1. Fix the bug existed in the Time Zone Setting Problem: Unable to save the data entered by using the scroll-down key. Result: Now the user is able to enter the data by pressing either the scroll-down and scroll-up key.

  1. Fix the bug existed in the PAE Function Problem: Incorrect data calculation occurred when the RA axis of the telescope (AX2) was pointed at a negative angle. Solution: Now the PAE functions properly when the RA axis (AZ2) is pointed at a negative angle.

3.27,  2010.01.06

  1. Fix the bug in the SAO catalog regarding disabling the key-pressed slewing Problem: Unable to drive and slew the telescope with the directional keys after browsing the SAO catalog. Result: The directional keys are properly activated after browsing the SAO catalog.

  1. Fix the bug in the User Object coordinate editing. Problem: In the User Object function, under RA-Dec format, when the user enters an object with a declination angle between 0 and -1 degree the value becomes positive after the coordinates are saved. This causes GoTo pointing inaccuracy. Result: The user-entered coordinates are saved properly.

  1. Fix the error in the database of NGC, IC catalogs. Problem: In the NGC and IC catalogs, the coordinates of the objects located between 0 and -1 degree in declination always read as positive. This causes GoTo pointing inaccuracy. Result: The coordinates are read as their true values.

Aggiornamento del Firmware

Se compare il messaggio di errore Can not connect to a SynScan hand control (non posso collegarmi alla Pulsantiera SynScan), controlla il cavo di collegamento. Assicurati che sia in buona condizione. Chiudi tutte le applicazioni sul computer che possono occupare la porta RS-232 e riprova. Se ricevi il messaggio di errore Firmware update failed... (aggiornamento del firmware fallito), rimuovi la spina di alimentazione e ripeti la procedura di aggiornamento.

La velocità di comunicazione dei dati fra SynScan ed il computer di base è fissato a 115 kbps. La porta RS-232C su alcuni computer può non sostenere tale velocità. Se l’aggiornamento del firmware fallisce dopo alcuni tentativi, devi ridurre la velocità di comunicazione premendo il tasto SETUP sulla Pulsantiera dopo che hai inserito la spina di alimentazione elettrica. Ciò ridurrà la velocità dei dati a 9.6 kbps. Lo schermo LCD mostrerà la parola Lo nell’angolo destro più basso per indicare che è ora la velocità di comunicazione è bassa. La procedura per l’aggiornamento dei firmware rimane la stessa, ma per completare ci vorranno circa 240 secondi.
