Signals on J10 change as follows:
Pin From To
35 ANIN0 /EXT_IRQ3
37 ANIN1 VDDX
39 ANIN2 MIC_GND
41 ANIN3 MIC_GND
46 /SHDN_RS232 VCC
DIP switch signals SW2 and SW3 on connector J3 have been eliminated
JP4 is now the Vee selector. The panel data voltage is factory-selected with R288 or R289
JP1, JP2 and JP5 (formerly Vee settings) have been removed
JP4 has been changed from flat panel voltage select to Vee polarity select
The BATPOS input no longer powers the system in sleep mode. It only powers the RTC
The "30V" output has been removed
UCB1200 codec and I/O chip has been removed. Digital I/O functions (EIO0-9)are handled by a
programmable logic device. The mono microphone and speaker are no longer available, nor are
the four analog input channels that the UCB1200 formerly provided. A/D inputs are still available
on the ADSmartIO.
Option to pull /BacklightOn signal up to 12V_IN (J3.48) is no longer available (this can be done
on the personality board).
3.3V pull-up on /IRDAON signal removed
/EXT_IRQ1 and /EXT_IRQ2 interrupts are mapped to different SA-1111 ports
/EXT_IRQ2 doesn't have pull-up or pull-down
