The HS-2604 is a 100/133MHz FSB VIA VT8606 chipset-based board designed for Mini PCI Local Bus VIA C3 EDEN 400/667MHz
Embedded CPU.

These features combine and make the HS-2604 an ideal all-in-one industrial single board computer.

Additional features include an enhanced I/O with CRT/Panel, three LAN, and 4COM ports interfaces.

Its onboard ATA/33/66/100 to IDE drive interface architecture allows the HS-2604 to support data transfers of 33, 66 or 100MB/sec. to one IDE drive connection.

Designed with the VIA VT8606 core logic chipset, the board supports VIA C3 EDEN 400/667MHz Embedded CPU. The VIA VT8606 integrated S3 3D supporting CRT/Panel displays up to 1920 x 1440.

System memory is also sufficient with the one SO-DIMM socket that can support up to 256MB.

Additional onboard connectors include an advanced USB and IrDA ports providing faster data transmission, a DOS-compatible DiskOnChip socket with a maximum capacity of 288MB. And two external RJ-45 connectors and one 10-pin header for 10/100 Based Ethernet use.

To ensure the reliability in an unmanned or stand alone system, the Watchdog Timer (WDT) onboard HS-2604 is designed with pure hardware that does not need the arithmetical functions of a real-time clock chip.

If any program causes unexpected halts to the system, the
onboard Watchdog Timer (WDT) will automatically reset the CPU or generate an interrupt to resolve such condition.
