Controlling nexstar via usb to rj45

Post by 2crows » Mon Feb 05, 2018 7:33 pm

Purchased astrotelescope software, hope to be able to control Celestron scope under Mac v10.3.3, using usb to the serial pc port on telescope.
Astrotelescope loads fine, “nexstar detected”at open. “No telescope” changed to “nexstar”, get error message “invalid echo response!”.
Home, slew, sync,stop and directional control stay grayed out.
Other info:
Under preferences, am using nexstar driver, serial port matches serial port shown in system information- usb.
Telescope has nxs 4.21,mc 5.14.
Usb/rj45 cable has ftdi chip, ftdil v6.00
Driver is ftdi 2.2.18
Have looked at various software logs, but I’m not sure what to look for, nothing obvious found.
Any thoughts?
Thank you.

Hi, what device name did you use in preferences? Make sure you use /dev/cu.something. There is probably also /dev/tty.something, but it is device with modem control. Peter

Hello, Peter.
Device name is /dev/cu.usbserial-A9078TPQ.
In Mac system information, under hardware/usb, I find
Ft232R usb uart:
Product ID 0x6001
Vendor ID x0403
Version 6.00
Serial number a9078tpq
Speed up to 12Mb/sec
Manufacturer FTDI
LocationID 0x14100000/2
Is there any other info that would help?
Thank you.

This looks correct. What telescope is it and what is the firmware version (of the hand controller)? Is there some more messages in console (/Applications/Utilities/Console). Thank you, Peter

hello again, Peter.
in response to your questions, telescope is a celestron cpc 800, HC (hand controller?)is NXS 4.21, MC is 5.14.
There are lots of messages in console (a shocking number, really), but I can't see that they are relevant. I included a sample below, from around the time I turned astrotelescope on.
I noticed something else.
First, with the serial cable plugged in, I got the following error messages on the hand controller:
No response 17 (some features will not work properly)
No response 16 (invalid model)
I also just noticed that the "invalid echo response" message comes up even when the serial plug is not connected to the telescope. If this means anything.
I am told that some of those who control their scopes remotely (Windows users) go through the rj25 aux (6p6c) port on the scope, just as the hand controller does. I don't understand why, though.
I have ordered another usb to serial cable, from a different supplier, with a different chip and driver. Unless you see something obvious that I'm doing wrong, I think you may best wait on your researches until I've tried that.
Thanks for your patience.

Hi, actually these errors are not related to AstroTelescope (you can filter them out by search box in top right corner) and don't worry, there is always a lot of messages.

It is probably possible to connect Celestron mount directly, but in this case you need different "programming cable" (and I'm not quite sure if it is still available and if it works with recent mounts). With the cable which came with the mount, you can connect just to the hand controller.

Do you have the original cable? I'm not quite sure if RJ45 is the correct one, it should be actually RJ11: http://www.nexstarsite.com/PCControl/RS232Cable.htm

Peter,
thank you, I will try this. The cable is still available, it should mate with the usb to serial cable I had ordered.
Will report on my success....

Peter, thank you for your help, and patience with a newcomer.
Everything seems to be working now.
For the reference of any other newcomers, the usb/serial adapter that is working is from Plugable Technologies, model pl-2303-db9, and the cord from this to the telescope handset is the Celestron part #93920.
Onward and upward to AstroGuider!

Thank you very much for info! PL2303 is Prolific chip, it always works with Mac unlike many others :) Peter
