Here is a link to the datasheet for the FTDI FT232R chip that is used in the iEXOS 100. This datasheet has reference schematics for the connector pinout and how it is connected to the

I don't know how much Bresser Germany would give you for your damaged mount in exchange for a new one. We have not had to replace or repair any of the iEXOS 100 mount electronics thus far after

sooo ... board is broken ... red led does not shine anymore how expensive is a new board ????? Gesendet von Mail für Windows 10 Von: rene schoffelke via Groups.Io Gesendet: Samstag, 7.

Hi is there a circuit diagram of the mini usb connection? then I can solder a cable to other solder points. the area of ​​the mini usb so yes, so not the whole board. rene

That’s a question for Jerry. Post it on the forum. I found your Facebook profile I’ve emailed Bresser, which is in Germany, to see if they can repair it. Kent

how expensive and where can I get a new board? the mini usb port has been torn off the board ... 3 of the solder joints have come off the board ... are there any other points where I can

The RS232 header (with no header pins) is provided for testing purposes and communications traffic monitoring only. The pinout for this header is 1-GND, 2-DTR, 3-TX, and 4-RX. Pin 1 is the square pad.

a schematic would be great, then you can solder a new usb plug with cable ... Would be a pity if I could not use the mount anymore ... a factory reset or hard reset, so that the mount goes

Hi, Jerry, I noticed there is an UART header on the board as well, but its pinout is not described anywhere (for some reason, I suppose). Also, is this UART different from the one connected to the USB

Hi Rene, I assume you mean that the mini usb connector on the iEXOS 100 is damaged and you cannot connect to it anymore. Unfortunately, there is no simple way to connect to the serial port on the

Hi today I demolished the mini usb ... the mount is on serial ... per config, I can not switch to wlan ... is there a possibility for a factory reset on the board? Warranty is not broken. Can I

Can I possibly use the rs232 port on the board? .. There is a cable with usb USB to RS232 TTL PL2303HX PL2303 Converter USB to Com Serial Adapter 4 Pin from ebay

Hi Mark, Thanks for the detailed replies. For my case, I do have excessive backlash or rather, loose gear coupling, since I purposely left the RA mesh extra loose with an East heavy weight bias to

Vince, I find I don’t have to make a special effort – just do normal polar alignment with the polar scope. There is usually enough error so that the drift is noticeable but not awful. As to what

I think there is no good answer. Be interesting to hear what he thinks. Polar misalignment means the arcs cut by the scope are not centered on the arcs cut by the stars. Thus the mount might be

Mark, Good advice. I had forgotten about dialing in a little PA offset. Just to be sure, is this using Az adjustment or altitude? How much off is enough to force north or south only? -- Scope:

Vince, If you bias the mount slightly heavy east and guide at less than 100% correction, the RA never reverses and backlash there is irrelevant. Trying to remove backlash by tightening the gears can

Vince, A 1200 second exposure. TWENTY MINUTES. Two periods. Swinging an 8" newt, for goodness sake! I think you now hold the record for exposure length. Congratulations! :-) - Bob -- Mounts:

All, I've been doing a series of test to try to extend my total guide time and here is what I've been able to do so far: 1x 1200 second exposure @ ISO50 (too much light pollution), no UHC filter and
