1. Introduction
NOVA-4898 is designed for limited space applications with only
the size of a 5 1/4 " hard drive. It supports the full functions of an
AT& ATX-compatible industrial computer on a single board. The
NOVA-4898 is equipped with a low-power consumption and high
performance GX1 processor on board. It also contains an SDRAM
DIMM socket that can support up to 512 MB memory.
The NOVA-4898 provides an Ethernet interface, audio interface,
and socket for DiskOnChip, EIDE interface, one parallel port, three
RS-232 serial ports, one RS-232/422/485 serial port with
auto-direction, and a PS/2 keyboard/mouse interface. The built-in
SVGA/LCD display controller supports both the CRT and LCD display
simultaneously. It offers the resolutions of LCD screen up to 800 x
600 and CRT resolutions up to 1280 x 1024 @ 256 colors &1024x
768 @ 16 bpp. It also provides TV-OUT interface for PAL or NTSC TV.
The display type is configured through software utility. The Flash
ROM contains both the system BIOS and the VGA BIOS. If
necessary, reprogramming the Flash ROM allows modifications.
The RS485 has an outstanding feature of intelligent directing
control, which eliminates the extra control signal such as RTS. With
this feature you can develop your program using your normal RS232,
no need to change to a special control routine. This feature is
especially important in WINDOWS programming where the program
do not allow you to catch the control pin freely.
Finally, one PC/104 connector and one PCI slots are included for
the future application that might come in handy.

3.15 Digital I/O (CN12)
One characteristic of digital circuit is its fast response to high
or low signal. This kind of response is highly needed for
harsh and critical industrial operating environment. This is
the reason we designed 4-bit digital inputs and 4-bit digital
outputs on the NOVA-4898.
Digital Input and Output, generally, are just control signals.
You can use these signals to control external devices that
needs to turn On/Off circuit or TTL devices. The register
address is 240H, 260H or 280H, which is selected and setup
in BIOS SETUP MENU. You can read or write data to the
selected address to enable the function of digital IO.

Appendix A. Watchdog Timer
The Watchdog Timer is a device 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 normally, hardware
on the board will perform hardware reset (cold boot) to bring the
system back to a known state.
Three I/O ports control the Watchdog Timer.

This action will enable and activate the countdown timer, which
will eventually time out, and reset the CPU to ensure that this reset
condition does not occur. The Watchdog Timer must be periodically

refreshed by reading the same I/O port 043/843H and 443H. This
must be done within the time out period defined by software setting,
please refer to the example program.
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.
Note:
When exiting a program it is necessary to disable the Watchdog
Timer, otherwise the system will reset.
