Synscan power supply wrong figures in manual?

Recommended Posts

I recently purchased a EQ5 mount with synscan. But rather then use the car adaptor running though a 3 pin convertor i bought a 12v 500mA DC power supply. The back of the manual states it requires 100mA (see image). So here i am thinking great this will do. Wrong. Its enough to start the hand controller and go through all the set up but it doesnt seem to move any motors. This being my first attempt i wasnt sure if i was doing something wrong. Did the brakes need releasing? - No. are the cables going to the right sockets? - Yes. After much head scratching i went back to to start and used the supplied 12v car style plus in a convertor i had. Sure enough it all worked perfectly. okay went back to my 500mA and nope nothing worked. After searching the house for a 12v 1A DC supply with the correct plug and trying that, Sure enough it all works fine. Have they simply missed a '0' off the manual or am i missing something else here? Tomorrow i'll probably go an exchange it for this 12V 1000mA Power supply. I'll let you know how i fair. And for anyone checking for power supplies (Like i did) your looking for a 5.5mm x 2.1mm power tip to for the unit.

Yes I remember going through two different adaptors before finding a 1200mA 12V supply worked. You know it works when you hear that click followed by the beep from the hand controller.

Perhaps the manual is referring to the amperage required to power the hand controller alone, a useless number since the motors require at least 1A when slewing at full speed.

The voltage and amperes in the photo only refer to the requirements for updating the handsets firmware. The mounts requires  11-15v dc with a continuous current of 2 amps (more is better) to ensure it functions properly.

Thats handy to know. Im not great on electronics but Amp wise it will only take what it requires? So if i was to get 3000mA id not damage the system?

Yep, I use 10\20 amp supplies (useful for powering cameras etc.) with no ill effects.

That psu should be ok.  The minimum requirements for a psu are 12v dc with a continuous regulated output of 2 amps.

Couldnt get anything closer then 1A today the 1.5 was a detachable end with different sizes. But as its outside im not willing to risk to many connections in the system.

But have tried it on the set-up and it works. But will be searching works psu stock for a compatable one with more Amps.

1.5 amps might work for a short while but if the mount tries to draw more current than the psu can supply then you will get problems.

      So I have an ETX 70 but I would much rather not use batteries, would prefer just connecting straight to the wall. Was wondering how I would go about that, there doesn't seem to be anything now-a-days because of its age. Thanks for any help

      I was hesitant to write this earlier, but I wanted to try all possible ways to get my new SkyWatcher 250P GOTO allgined, but to no avail.
      I have followed the instruction manuals of both the synscan and SW, and managed to get the message "alignment successful" multiple times on the handset or the app. The closest I got when I tried to dial a different star was a 20 to 25 degrees off on the azimth axis. Most times it's off by a margin on both axes.
      I have tried aligning around 30 times on more than 5 diffrenet occasions, different locations as well. I end up ignoring the thing and switch to navigating manually as the eager friends want to observe instantly, but we ran out of objectes and the planets are not close anymore, so I figured it's time to get deeper DSO's and sort out the GOTO.
      Here is what I do:
      • I level the scope to the zero reading on top of the base
      • I make sure the base is level with a spirit level I bought recently
      • I point the scope northish, but latley I bought compass to pinpoint north
      • I plug all equipments in and then switch on the power from a lead acid battery
      • I enter the date ( US fromat, month before day 😕 )
      • enter correct time zone obviously
      • the coordinates in the format of E 000 00 , N 00 00 
      • As for  elevation I use "my  elevation" app, not sure if it's accurate. Does this entry have to be that accurate?
      • I tried both brightest star and the 2 star align methods on the handset (which seems to be the same thing apart from the brightest method having an extra menu asking for which direction you are pointing at)
      I even used the synscan app and the synscan pro, and tried the 3 star align method. The app uses location and enters all data automatically
      •I use the top and right arrows as the last press before centring the star in the eyepiece as  recommended by the manual
       
      These are the steps I follow when I align , is there anythung I missed? Your kind help is much appreciated.
       
      Update: issue solved, check the reply in the second page

      Sooo...I'm getting quote frustrated here. This spring I tested my HEQ5 with guiding. The synscan controller was connected to the computer trough the USB plug on the hand controller. This worked like a charm in my living room. On the new controllers you dont need the rs cable. But when I tried the whole thing with guide cameara for some live shooting, it just did not work. I get something wrong with the com port in decice manager, driver not working. I have tried 3 different drivers. The whole thing responded, connected and was guiding when i did a dummy test before the summer. So setup is pc-synscan via usb for pulse guiding. Can it be a problem with windows 10? What t h.... just happened? Where can I find a driver that works? And believe me it worked 5 months ago, argh. Thanks for any respons and support

      With several clear nights over the past week,  I've been playing with the Synscan Pro app (Android) in conjunction with a Synscan WiFi adapter on an EQ3Pro mount.  I have to say I'm generally quite impressed.  Much cheaper than buying a traditional handset.  
      However,  this evening I was trying to "creep up" on the Andromeda Galaxy by star hopping towards it via Mirach,  Mu Andromedae and Nu Andromedae.  Mirach was no problem but the other stars were not available for selection in the app.  Am I missing something?  I couldn't find any way to enter an SAO number or any other catalogue number to find the minor stars.  
      Is this a limitation of the app?  Or the adapter perhaps?  Or is it me? 
      Clear skies, 
      Mark.

      What is your experience with the small Tracer 12v lithium batteries?
      My new manually driven dobson will have a mirror cooling fan and, although I might not using it, I would like to think ahead about potential power sources. 
      What are your recommendations for a small power supply?
      Thanks,
      Piero
