I am trying to connect my new laptop to my LX200. I have an original
10" Lx200 (1998) and The Sky version 4 level 2. This works perfectly
on my old laptop with a serial port. My new laptop only has usb ports
so i have bought a serial port to usb adapter which seems to work ok.I
am connecting using the rs232 port on the lx200 but the software
settings in the Sky software only lists com ports 1-4 and baud rates.
I have tried these but with no success. Has anyone tried to connect
using this version of the software by usb ?.Any idea on settings?.
Andy. |

You need to make sure your USB adapter is mapped to one of the first
four COM ports. The details for doing the vary slightly with the adapter
you are using, but generally you can go into Device Manager and either
(1) find the adapter listed separately, and open its properties dialog
to assign ports, or (2) open the properties of your ports and assign the
COM number to the one being used by your adapter.

Critically important, and also Reason # 3x11e39, nudge-nudge, wink-wink

Actually, it's a problem caused by poor design of most of the adapters
themselves, not so much an OS problem. The USB spec provides a mechanism
for devices to uniquely identify themselves- something that is
critically important in the case of hardware that is mapped to a static
system resource. A few manufacturers (Keyspan, for instance) do this
properly, so there is never any problem. You install the device the
first time, the system asks you which port you want to assign, and
that's the end of it. But most USB/serial adapters fail to provide an id
code, so the system (any system) has absolutely no way of knowing how to
reassign ports, forcing a sort of guessing game that often results in
orphaned COM ports.
