External IR Receiver Connections
Use an external Xantech IR Receiver in cases where a hand-held remote
needs to be pointed somewhere other than at the MRKP1 or in cases where
additional interference requires the use of a different type of IR receiver or IR
receiver mounting location. Typical IR Receiver locations are near a TV or other
equipment such as a Local Source (DVD Player, A/V Receiver,…etc.). A CAT-
5 cable can be used to extend the IR receiver’s wire, if necessary. Refer to the
bottom of the Specifications section (page 20) for wiring instruction when using
CAT-5 cable to extend the IR signal.
By default, the MRKP1 External and Internal IR receivers are both active.
Having both active, in some cases, can cause issues with IR signal reflection
and/or multiple processing of the same IR command. Therefore, in such
specific cases it is advisable to disable the Internal IR when using an external
IR receiver
(Internal IR can be disabled by removing jumper clip on item #2 of
Figure 2.3)
.
