Network Activity Indicator – Router 5000
Although the Router 5000 does not provide separate network indicator pins, you
can use the CP[4..0] pins with appropriate indicator circuits to provide this
functionality. For an RX network activity indicator, connect an appropriate LED
circuit with pulse stretching to the Router 5000 CP0 pin. For a TX network
activity indicator, connect an appropriate LED circuit with pulse stretching to
the Router 5000 CP2 pin. If you add LEDs to the CP0 or CP2 pins, you must
add a buffer to ensure that the LED’s operation does not interfere with network
communications.
