C.1.3 Digital Output Connections
To run the digital output sample programs, you must connect at least one demo board LED to a 100 mA
sinking driver on the RabbitFLEX board. There are four demo board LEDs, so you may connect up to four
100 mA sinking drivers.
Connect the green wire of the cable assembly that corresponds to the selected digital output to LED1,
LED2, LED3 or LED4 on screw terminal header J1 on the demo board. Connect the polarized connector
of the cable assembly to the connector that has the digital output(s) you selected on the RabbitFLEX
board. Figure C.2 shows the demo board LEDs connected to pins 2, 4, 6 and 8 of the cable assembly. In
this case, the polarized connector of the cable assembly should be connected to one of the connectors on
the RabbitFLEX SBC40 that has 100 mA sinking drivers on pins 2, 4, 6 and 8.
