ISA and PC/104 are sought-after standards in the industrial PC sector. The VDX3-6724 ISA slot CPU in half-size format from Comp-Mall has a PC/104 slot and can therefore be supplemented with measurement and control cards in ISA format via a backplane or PC/104 slot to suit specific applications. In addition to retrofit applications, the slot CPU is suitable for machine control and industrial automation where low power requirements play a role. The Vortex86DX3 processor with 1 GHz is onboard and the DDR3 memory can be expanded to up to 2 GB. Displays are connected via VGA (1920 × 1080 pixels) or LVDS (1024 × 768 pixels). 1 × LAN, 1 ×GbE LAN, 2 × RS232, 2 × RS232/485, 4 × USB 2.0, 16-bit GPIO and 1 × parallel port are available for data output. A programmable watchdog timer improves the system's reliability. The current requirement is specified as 1000 mA at 5 V. The operating temperature is between -20 °C and +70 °C and can optionally be extended to -40 °C to +85 °C. The slot CPU supports DOS, Windows XP and XP Embedded, Windows 7 Embedded, POS Ready, Embedded Linux, but also real-time capable operating systems such as Windows CE 6 and 7, QNX, FreeBSD and VxWorks.
