If commands are being sent via a USB/serial converter then some things USB-related:



1) a bad USB/serial converter...

2) a bad or poor performing USB hub...

3) USB problems with your computer

Thanks Ray--seems like the obvious problem.�� I'll try my other usb-serial converter.Geoff

You don't say what servo control you have, but I suspect that you have a CP2, in which case you should not use the telescope as your guider input. Use only the relays. The CP2 does not have the proper command structure to accept an Ascom guide command.��Rolando

Do a calibration run with�� "telescope" and see if it works. You may have a buggy USB-Serial converter.��Rolando

I'll try that when I go down to my dark sky site next new moon.��
