Using the IR 452 with the DVCM 50
4 . Press the IR 452 button for the function you want to initiate. The following
takes place:
• The remote control sends an infrared (IR) signal to the IR Link or IRL 20.
• The IR Link or IRL 20 relays the IR signal to the DVCM through the
DVCM’s IR In port, to which the IR Link or IRL 20 is connected.
• The DVCM recognizes the signal it receives via the IR In port, and
responds as if its own equivalent button were pressed, issuing the
command to the DVD/VCR.
Setup operations on the DVCM 50 cannot be performed from the IR 452.
Buttons on the IR 452 remote control
The buttons on the optional IR 452 Remote Control duplicate the DVCM 50’s front
panel controls for normal operation. The DVCM responds to IR signals from the
IR 452 as if the corresponding button were pressed on the DVCM.
The IR 452’s Display Power button and the VCR and DVD control buttons do not
function until commands have been stored in the DVCM’s memory. The IR 452’s
VCR buttons control the fi rst (lowest address numbered) VCR connected to the
DVCM. The DVD buttons control the fi rst (lowest address numbered) DVD
connected to the DVCM.
Commands are transmitted from the DVCM’s IR Out port via the IR Emitters to
the DVD/VCR when the corresponding button is pressed on the IR 452 or on the
DVCM’s front panel.
The following IR 452 buttons do not have equivalents and cannot activate
