Page 22: Irda Infrared Interface Port
IrDA Infrared Interface Port WAFER-4821 has a built-in IrDA port supports Serial Infrared (SIR) or Amplitude Shift Keyed IR (ASKIR) interface. If you want to use the IrDA port, you have to configure the SIR or ASKIR model in BIOS>Peripheral Setup>COM4. Then the normal RS-232 COM4 will be disabled. -
Page 23: Digital I/O
This kind of respond is badly needed for harsh and critical industrial operating environment. That is why we design 4-bit digital inputs and 4-bit digital outputs on the WAFER-4821. Digital Input and Output, generally, are control signals. You can use these signals to control external devices that needs On/Off circuit or TTL devices. -

Page 33: Appendix A Watchdog Timer
Appendix A Watchdog Timer Watchdog Timer is provided to ensure that standalone systems can always recover from catastrophic conditions that cause the CPU to crash. This condition may have occurred by external EMI or a software bug. When the CPU stops working correctly, hardware on the board will perform a hardware reset (cold boot) to bring the system back to a known state. - Page 34 A tolerance of at least 5% must be maintained to avoid unknown routines within the operating system (DOS), such as disk I/O that can be very time consuming. Therefore if the time out period has been set to 10 seconds, the I/O port 443H must be read within 7 seconds.
