6.5.1 Setting the MACHINE #
The MACH. # determines the position of an
OMX-SW5x5
unit, specifying
which
OMX-SW5x5
unit is being controlled when several
OMX-SW5x5
units connect to a PC or serial controller. Set the MACH. # on an
OMX-SW5x5 unit via DIPS 1, 2, 3 and 4, according to Table 5.
When using a stand-alone
OMX-SW5x5
unit, set the MACH. # to 1. When
connecting more than one
OMX-SW5x5
unit, set the first machine (the
Master) that is closest to the PC, as MACH. # 1 (dipswitches are set to OFF).
