 Expansion Interface: PC/104 (ISA)
 Battery: Lithium 3V/210 mAh
 Enhanced IDE interface: One channel supports up to two EIDE devices . Sup-
ports UDMA 33 mode
 CFC: Solid State Disk (SSD) supports one 50-pin socket for CFC type I (type II
optional) shared with primary IDE
 External SPI onboard Flash: Optional onboard 4MByte SPI Flash Disk (Sup-
port by request for boot device or storage on DOS OS)
 Serial ports: Four serial RS-232 ports, one of them can be configured to RS-
422/485 ports by jumper J2
1. CN7 provides two RS-232 serial ports (COM3/4).
2. CN12 provides two RS-232 serial ports (COM1/2).
3. CN6 provides one RS-422/485 serial port adjusted by J2, and you just can
select either COM2 (RS-232) on CN12 or RS-422/485 on CN6.
Note! For wide temperature version, CPU speed would be downgraded.
Note! When you use the CF socket , the IDE connector can only be attached
to one IDE device.
Note! 1. When RS-422/485 on CN6 is enable, COM2(RS-232) on CN12 will
be disable.
2. When using PWM Brightness control, COM2 will be configured as
PWM function using. You can select either COM2 or PWM Bright-
ness control function.
