Button associations (virtual mapping) for an IRCM-DV+
By design an IRCM-DV+ can be assigned paired module addresses (by DIP switch) of either 1&2 or 3&4 only. It cannot
be assigned to addresses 2&3 or 1&4. The odd-numbered module address (1 or 3) is reserved for DVD control, the even-
numbered module address (2 or 4) is for VCR control. The address DIP switches must be set in order for the MLC to
recognize and reserve memory space for the module. Refer to the Control Modules User’s Manual.
To use an optional IRCM-DV+ with an MLC 226 IP, you need to associate the DVD portion of this module with an
MLC input selection butto, and also associate the VCR portion with a different MLC input selection button. The
associated button must be selected (pressed) in order to activate and use the VCR portion or the DVD portion of the
module. You cannot activate both parts (VCR and DVD) at the same time. If you do not associate (map) the IRCM-
DV+’s addresses (1&2 or 3&4) with MLC buttons, you cannot activate and use either the DVD or the VCR part of the
IRCM-DV+.
N
For MLC 226 Series MediaLink Controllers, you can assign both the DVD and VCR portions of an IRCM-DV+ to the
same input selection button. A and B must both be inputs that are set up for input switching mode (fi rmware control)
via Global Confi gurator.
Here is how to determine the value of
X? for the following commands:
