DCF77 Radio Clock - PCI/PCI-X Bus
 The PCI511 is a DCF77 radio clock for synchronization of computers with a PCI or PCI-X slot. It receives the longwave radio time signal from the DCF77 sender located near Frankfurt/Main, Germany.
IRIG Generator
 The board TCG511 has been designed for the generation of IRIG and AFNOR standard time codes MEINBERG: Quality Management System
