详细内容
The PCM-5821 is a highly reliable single board computer based on the NS GX1 300MHz CPU. It offers built-in functionality comparable to a complete industrial PC system, including a VGA/LCD controller, network communications, compact flash diak in a small 8" x 5.75" form factor. For maximum performance, the PCM-5821 also supports an SDRAM SODIMM socket that can accept up to 128 MB memory. On-board features include an Ethernet interface, audio interface, socket for Compact Flash Card, Enhanced IDE interface with up to Ultra DMA transfer protocol, one parallel port, four serial ports （RS-232 ａnd RS-232/422/485） with DB-9 connector, ａnd a mini-DIN PS/2 keyboard/mouse interface. An SVGA/LCD display controller （LCD, ａnd CRT displays） allows LCD screen resolutions up to 800 x 600 @ 256 K colors. The PCM-5821 complies with the "Green Function" standard ａnd supports three types of power saving features: Normal, Doze, ａnd Sleep modes. The display type configuration is done through software. A single Flash chip holds the system BIOS ａnd the VGA BIOS. This minimizes the number of chips ａnd eases configuration. You can change the display BIOS simply by programming the Flash chip. It also offers faster data access ａnd longer MTBF than mechanical disk drives ａnd is an ideal solution for critical commercial or industrial applications. The watchdog timer ensures the system will be reset if it stops due to a program bug or EMI problem.
