Module expands PC/104 platform capabilities.

Press Release Summary:

Measuring 1.65 x 3.55 in., XBLOK® modules provide expansion capabilities to PC/104 platforms by providing up to 2 functional additions, such as Ethernet and digital I/O. Unit increases stack height by 0.6 in. and is designed so that there is 0.75 in. gap between opposing modules, allowing true conduction cooling. Available XBLOKs include 10/100 Base Ethernet; quad USB 2.0; four 48-line DIO; dual serial port; and fail-safe, battery-backed static RAM disk.

XBLOK®s Cut PC/104 Expansion Costs

Westminster, CO, January 07, 2005 - The XBLOK is a new product family from Octagon Systems that provides cost-effective expansion to the PC/104 platforms. The tiny modules are only 1.65" x 3.55", 44% the size of a standard PC/104 expansion module. Up to two functional additions, like Ethernet and digital I/O, may be added to a PC/104 system, increasing the stack height by only 0.6". This is half that of two traditional modules and with a cost savings of nearly 40%. The XBLOKs are designed purposely so that there is a 0.75" gap between opposing modules. This offers a significant advantage to those who have higher power processors. In the traditional solution, the heat is trapped under the first expansion module overheating both the CPU and expansion modules. The XBLOK gap allows true conduction cooling and the elimination of hot spots. This can be critical when A/D cards are stacked above the CPU.

Available XBLOKs include 10/100 Base Ethernet; quad USB 2.0; 4, 48-line DIO; dual serial port; and a fail-safe, high-speed, battery-backed static RAM disk. XBLOK prices range from $60 to $104. XBLOK modules are all rated for -40°C to +85° C operation. Availability is stock to four weeks.
