RS232 computer to RS232 NEQ6 mount

[Nicola Hannah Butterfield]

As the title suggests, does a direct RS232 to RS232 cable work in this situation, this is not USB to RS232, I have read that bit up, but finding it unclear as to RS232 to RS232 needs anything in-between as RS232 cables I can get cheaper, the cable will be run from the computer system in the shed to the scopes final resting place (eventually).

e.g. 5m £6

I think you might just need to be sure that it is a Null Modem or Null Modem with Handshake cable.

But, wait for someone else to confirm, pretty sure a straight through cable won't work.

Connecting two pieces of equipment together just because they have the same type of connector isn't a good idea. You need an EQDIR cable compatible with your mount or use the supplied serial data cable to the handset and send commands through that.

Also, the serial port on your computer is for sending RS-232 commands to serial devices. It just happens that the port uses a DB9 socket similar to the one on the mount. The mount isn't a serial device, but the handset is.

I take it this is the usb D port on the controller, I don't think it came with a cable for that, the manual only has two ports on the controller, my controller has three, one to mount RJ-45 a six pin presume RJ-12 and a USB D, so I can connect using a USB to USB D cable using that port.

Yes you can.

@Cornelius Varley

cheers, have those in abundance.

I know not the best way but just setting it all up.

@Cornelius Varley5m USB D cable ordered, and a 5m USB B for the camera, anthing else for a basic computer controlled system

You will need a planetarium programme such as Stellarium or Cartes du Ciel . Stellarium has its own inbuilt drivers, so no more software is needed. CdC requires Ascom plus the Skywatcher ascom drivers from the same site. Another alternative is to use either Stellarium or CdC with Ascom and EQMOD .

Sorry, got the above, I have been using for years, just never applied it beyond casual use before.

I know of eos backyard, what other sort of software does similar image capture, if I may ask.

I am getting there, only got the new mount two weeks ago.

Well if nothing else I can at least now control the mount via the handset from the shed, and I won't need to go to the mount to adjust for any drift (hopefully)
