Re: Cable recommendation?

Hi Drew,

In case you are not aware of this just changing the button rate in the drop
down list of PulseGuide doesn't actually send any commands to the mount to
change the rate. Only when you press a button does the rate command get
sent, followed by a start move command. Then when you let go a stop movement
command is sent followed by a command to restore the button speed to the
guide rate that is set in PulseGuide.

Subject: [ap-gto] Cable recommendation?

I am having trouble with Pulseguide not always sending to the mount.
FFor example sometimes changing button rates doesn't take. I suspect
the problem is dodgy cables.

I have:
Mount >
Short Serial cables >
pretty high quality Serial to USB connection >
HP powered USB hub at the mount>
USB cable from hub to laptop (about 25 feet)

I suspect the problem is the Serial or the USB cables.

1) Do people have specific recomendations as to brands of serial and
USB cables and where to get them (preferably where to order
them online)

2) Should I have short serial cables, the hub on the mount, and a 25
foot USB run Hub-to-laptop or should I have a 25 foot Serial cable,
then convert to USB right at the laptop?

Thanks in advance
