between source and destination channels. Ethernet audio channels only go to those destination channels that
request them, and the coordination of these sources and destinations is handled by the IGMP switch/router.
USB
Like the ethernet connection, the USB connection can be used to program, monitor, and control the MAP-6L
(no USB connection available on a MAP-3 unit). This connection can be used to send and receive files from the
MAP unit, as well as configure the unit, and control any system layout. Unlike the ethernet connection, there
are no audio channels available via USB.
Logic I/O
The Logic I/O ports on the rear panel of a MAP unit are RS-485 communication ports for Ivie SmartControls

as well as physical controls, such as potentiometers, contact closures, and LED outputs. Any Ivie SmartCon-

r24VDC power, which is supplied on pins 4 and 5 of the
RJ45 connector. For consistency in iFlex installations, and assistance in technical support, Ivie
uses the TIA/EIA 568B standard for RJ45 connector wiring. Care should be taken in the wiring
of RJ45 connectors on the CAT-5e cable, as cross-wiring of the +24VDC can cause damage to
the RS485 communications electronics inside the MAP unit.
