Paramount MX User Guide
Software Bisque has experimented with many inexpensive USB extenders and most of them just do not
work. Even worse, some work "some of the time" but often result in strange or unpredictable behavior.
After adding any USB extender to the Paramount MX, if you encounter any unusual behavior with the
Paramount MX or device connected to the USB ports on the Instrument Panel, please see
"Troubleshooting Communication Problems" below.
Using Multiple USB Devices
Unfortunately, Software Bisque cannot guarantee the Paramount MX will work with every possible
USB/USB Hub/USB Extension/USB Device configuration. The number of hardware permutations is
virtually endless, and, based on our experience, inexpensive USB extenders or inexpensive USB hubs
usually introduce communication problems.
For example, we've encountered a configuration where an "innocent looking" USB hub in the chain of
computer/Paramount MX/Apogee Instruments CCD camera not only caused artifacts on the CCD
photos, TheSkyX Professional Edition would lose communication when the camera download photos.
No USB hub, no problems.
Generally speaking, do not buy inexpensive USB extenders or to connect a wide variety of USB devices
(hubs) You will regret it.
Troubleshooting Communication Problems
After adding a USB hub, USB cable extender or any other USB peripheral device to the Paramount MX
USB cable, if TheSkyX Professional Edition is unable to connect to the Paramount MX (with frequent
timeout errors or poor communication errors), remove every USB device except for the supplied 15-foot
USB cable. Then use the process of elimination and add one USB device at a time to determine which
one is problematic.
