CAT5e will fit an RJ11 plug with difficult but as you have experienced
the cable is to stiff for a flexible installation. Try using BELDAN 4
PAIR STP this is a very flexible cable. However, fitting RJ11 plugs
will be a pain but it can be done with the correct tools.

I have recently moved my LX200 operations into my house from an
outbuilding
located within about 70 feet from the LX200. My computer is now
roughly
150 feet from the LX200. I image with a ST-8.

With an eye to the ground issue when remoting the keypad this
distance, I
have now tried several cables unsuccessfully. I'm wary of trying
telephone
cable based on Doc G.'s comments in the archives. I have now
tried his
suggestion of trying cables with multiple conductors combined for
the
ground. This has worked for a day or two, but then I find that
either I
trip over the cable and shear the connection, or any one of a
number of
things cause the cable to lose connection. As I believe I may
have fried
my control panel recently because of an inadequate ground, I'm
pretty
concerned I may do the same again ($$$! or in my case £££!). Most
recently
I tried shielded cat 5 cable which I think would be fine
electronically,
except (a) the pares do not fit the RJ11 (i.e., wrong gauge), and
(b) the
pared wires are simply too brittle to take constant dragging
around when I
move from scope to house.

OK, with that background, I would like to use Doc G.'s suggestion
of a
separate ground from the keypad to the control panel. I am not an

electronics expert. Does this mean that I can simply run a ground
wire
from the metal casing of the keypad to the metal casing of the
control
panel? Or does in need to be from ground connection to ground
connection. In looking at the schematic of the control panel, I
assume the
keypad ground is just that--to the metal plate of the control
panel which
constitutes the ground. Or indeed is there a simpler way of doing
it?

Thanks!

Bob G.
