RoHS-Compliant Version RoHS-Compliant Version The EPM-4g and EPM-4h are RoHS-compliant. These models are functionally identical to the non-RoHS version of the boards. ABOUT ROHS In 2003, the European Union issued Directive 2002/95/EC regarding the Restriction of the use of certain Hazardous Substances (RoHS) in electrical and electronic equipment. The RoHS directive requires producers of electrical and electronic equipment to reduce to acceptable levels the presence of six environmen

2 Configuration / Operation Overview ELECTROSTATIC DISCHARGE Warning! Electrostatic discharge (ESD) can damage boards, disk drives, and other components. The circuit board must only be handled at an ESD workstation. If an approved station is not available, some measure of protection can be provided by wearing a grounded anti-static wrist strap. Keep all plastic away from the board, and do not slide the board over any surface. After removing the board from its protective wrapper, place

Console Redirection Console Redirection If there is no video device detected during boot up, BIOS keyboard and screen I/O can be redirected to the COM2 RS-232 serial port. CMOS configuration can be modified over this redirected console. ANSI or VT102 terminal emulation is recommended. When console redirection is enabled, press CTRL-C on the terminal emulator to enter CMOS Setup; the BIOS ignores DEL from a PS/2 keyboard. This is normal operation of the Lynx. COM2 is configured for st

CMOS Setup / IDE Configuration CMOS Setup / IDE Configuration IDE The Lynx has a single IDE channel to connect up to two hard disks, CompactFlash modules or CD-ROM drives. This basic IDE interface operates using PIO mode 0, resides on the ISA bus, and does not support the drive address register at I/O address 3F7h. It has been tested successfully on a wide variety of operating systems. IDE SETUP IDE devices include hard disk drives, CD-ROM drives, and some CompactFlash modules. Th
