Are you useing only one jaguar connected to the black jaguar at one time?
And to confirm that your cables are properly made when you hold the RS-232 and the RJ-11 cable face up so the contacts are facing you, are they the same or reversed. If there the same there made correctly if not you must make the cable so that they appear the same.
If they are done correctly the cables will resemble the cable
pictured here.
Lastly can you move the motors in BDC-COMM
