I’ve just bought a Skywatcher EQ6-R Pro. I’m trying to drive it from Stellarium using EQMOD but I’m running into a problem I haven’t the experience to solve.
This is my set up:
Windows 7 Laptop > 10m active USB 3.0 cable > 4 port powered Atolla USB 3.0 hub > Lynx Astro EQMOD cable > Mount (plugged directly into hand control socket)
When I first connected the mount to the laptop (a 2015 Dell Inspiron) Windows 7 searched for a serial/USB driver and installed it on COM 8 (according to Device Manager).
In Stellarium I created a profile for the mount but it wouldn’t autodetect the COM port. So I manually set it to 8.
When I try to connect to the mount it sits for a while and then tells me the connection has timed out.
Anyone have any suggestions as to where I should start to try and get the connection sorted please? Thanks.
I own a NEQ6 mount and EQDirect cable, but the RJ45 version. The NEQ6 uses a DB9 port, so I got an adapter but I need to wire it myself. See attached picture of my adapter + EQDirect. I am quite unsure how to wire my adapter. The first diagram here should tell me how, but I'm still not sure I get it. If I look at the EQDirect adapter (see attached close-up), it looks like on pin 1 & 2, when the diagram says there should be ground there. Also someone in an INDI forum told me I could ignore the 12v pin as it would be supplied by the mount, but the RJ45 actually seems to have something on those pins.
It's tempting to just look at the wiring of both adapters and trust the colors, but I'm afraid making mistakes here might damage the mount...
EDIT: I own this RJ45 to DB9 adapter. Would any of the proposed wirings in this document work for my need?
Hi, all..I need to change the AZ EQ6 GT pulse guide rate. I know there are direct commands that I can send via EQDIRECT to change the pulse guide rate of the mount. At the moment the max rate I can get is 0.9 x 15arcsec/sec. I am told this is too slow for fast guiding using the new Astroart7 full frame guide system.
Does anyone know the mount serial command string to change the guide rate?
Has anybody else had this problem?
I use a single, ageing laptop (HP620 8Gb RAM) running Windows 7 Pro 64bit to control my imaging setup using the following software;
Cartes du Ciel and EQMOD to control EQ5 Pro mount via EQDIRECT cable connected via powered USB Hub
BackyardEOS to capture images from Canon 450D via same USB powered hub
PHD2 for guiding using GP-CAM 130C and EQMOD pulse guiding
What confuses me is that some evenings everything works absolutely fine. Another evening, using exactly the same hardware, software and even connections (ie I always plug the leads into the same ports) the system will be working fine but then suddenly fail. The failure affects EQMOD indicating a timeout or port not available issue and the Canon 450D also 'locks' requiring a restart of the camera and BackyardEOS.
I have run USBTree during such a failure and it is showing that the EQDIRECT cable (ie serial converter) is still connected to COM4 (which is correct) and the Canon 450D is also still connected. I basically have to ensure that all the software is closed and any associated services also stopped. Of course, the scope is now pointing away from its home position so I have to move it manually back to 'home' before starting again.
My thoughts are that there could be a number of issues;
1. Use of a USB hub
2. A dodgy EQDIRECT cable
3. USB cables too long (ie about 5m)
4. Windows is turning off a connection (I have set the power management for each USB port to 'off')
5. Canon 450D somehow 'freezing'
When using this laptop, I turn off the Wifi and Anti Virus and Automatic Updates are also off.
It just baffles me that sometimes this system works flawlessly for hours and yet other nights it keeps failing.
Any suggestions gratefully received.
Thanks for looking.
