FUNCTIONAL DESCRIPTION
Figure 2.1 - Ultra High Density Matrix Module 40-534A: Functional Block Diagram
A functional block diagram is provided in Figure 2.1. The Ultra High Density Matrix Module is powered by a +5V
input via Compact PCI connector J1. The interface to the user test equipment is via the front panel mounted 200-pin
LFH connector, J2. The module comprises two PCBs populated with single pole, screened single pole or two pole
relays, depending on the module type. The PCBs are connected via a ribbon cable (for digital control signals) and
a socket (for switch signals). The relays are energised via control signals from relay drivers. The relay drivers are
addressed by PCI bridge U1 to output the required signal. Module configuration, i.e. dual 32x4 matrix, is determined
by hardwired links and data stored in EEPROM U8. PCI Bridge U1 is configured by EEPROM U2.
