Mostcommandswithvariables(exceptsetcommands)usetheVXM'sprogrammemory
space. Therequiredmemoryneededpercommandisspecifiedinthissection. TheVXM
has256bytes
ofprogrammemoryforeachprogram. Thereare5(0,1,2,3,4)programs.A
programcanbeclearedbya"C"andselectedbythe"PMx"command. Thedefault
programwhentheVXMispoweredupis#0. Usingdifferentprogramsisonlyrelevantto
userswhowillbeoperatingthe
VXMinastand-alonemode(P8.) UsingtheVXMina
RS-232interactivemode(P9.)wouldonlyrequirethatthedefaultprogrambecleared
aftertheRcommand.
AnabsoluteIndexis,amoverelativetoabsolutezeroposition,adistanceanddirection
fromthepresentpositioncalculatedbytheVXM
basedonabsolutezeroposition.
AbsolutezeroisestablishedwhentheVXMispowered-up,byuseofthe"N",orthe
" command.
Sending Commands to the VXM:
ThestandardRS-232communicationsettingsontheVXMare9600baud,8data,no
