Introduction 2.1. Highlights · Mini-ATX Single Board Computer The ATX baseboard is a small single implemented by an ATX baseboard board computer having industry and a Computer-On-Module standard Mini-ATX form factor. Single Board Computer functionality · Works with all CompuLab's is implemented by a combination of CoM's: X255, X270, F82, i686, a Computer-On-Module and an ATX iGLX, iVCF baseboard. · PCI slot · COM1 - 4 with RS232 / RS485 / The ATX baseboard can use any RS422 / TTL driver options CoM (Computer-On-Module) available from CompuLab. Several · LPT, GPIO, PS/2 keyboard and additional functions are implemented mouse interfaces on the ATX board itself. Functional · Host USB ports content provided by the ATX · Hard Disk Interface baseboard varies according to the module selected, enabling the · Connectors for an LCD panel and flexibility required in a dynamic CRT monitor market where application · One to three 10/100BaseT Ethernet requirements can change rapidly. ports · Single or Dual PCMCIA / CardBus slots · Video input processor CompuLab LTD. 5 ATX baseboard Mini-ATX Single Board Computer 2.2.
