FUNCTIONAL DESCRIPTION
A functional block diagram is provided in Figure 2.1. The Matrix Module is powered by +5V and +3.3V inputs via
Compact PCI connector J1. The interface to the user test equipment is via the front panel mounted 8-pin D-type
connectors. The module comprises a mother and two daughter PCBs which are mounted together in a sandwich
arrangement. The inner daughterboard is tted with the solid-state relays and associated driving circuit for switching
crosspoints X1/Y1 to X4/Y2. The outer daughterboard is identical to the inner and has the switching circuit for
crosspoints X5/Y1 to X8/Y2. The relays are energised via control signals from relay drivers on the daughterboards
which are fed with serial data from the control logic on the motherboard. The control logic is addressed by PCI bridge
U1 to output the required signal. PCI Bridge U1 is an FPGA which is congured by EEPROM U2.

SECTION 2 - TECHNICAL DESCRIPTION
HARDWARE INTERLOCK
The 40-555B-011-HI modules have an interlock feature that can be used to return the relays (assuming they are fully
functional) to their default unpowered state if the interlock connector is not in place or if the connection between the
two interlock pins is open-circuit.
Note: The mating half to the hardware interlock connector is supplied with the module in an unwired state,
the user must implement the link connections as detailed in this section to permit operation of the module.
The user connector has the following control pins:
●Pin1: A 3.3V output from a 100Ω series protection resistor
●Pin2: An Enable pin which is by default pulled low by a 10kΩ resistor. NO RELAYS WILL BE
SWITCHED BY THE MODULE UNLESS THIS PIN VOLTAGE IS RAISED TO 3.3V.
The pin can be raised to 3.3V by connecting to the supplied 3.3V pin above. This is a global Enable for
all the relays on the module. If the Enable pin is allowed to be set low then the module will continue to
disable the relay operation until the software resets the channels to be on.
●Pin3: A Status Readback pin which is raised to 3.3V when the Enable pin is set high AND the software
has reset the module to enable relay control. This is available as physical signal on the user connector
and its status can be read back by the software driver.
●Pin 4: A connection to PXI Ground
The interlock can be used in a variety of ways when multiple modules are used in a system:
●All the Enable pins can be linked together and a single switch used to pull the Enable high to 3.3V. The
enable pin can be pulled high using a user connection. The software driver can then enable or disable
individual channels.
●All but one of the Enable pins can be connected together and connected to the Readback Status pin
of one of the modules (Master Module). The Master Module then has its Enable pin connected high
(3.3V). To restart the system the software driver would then have to enable each module through the
Master Module’s Module Enable and then turn on each 40-555B through its Module Enable.
●Each module can be independently controlled by linking its Enable pin to its 3.3V pin, if the user
connector is disconnected or if the link between the interlock pins is open-circuit all the relays will return
to the default unpowered state and will require restarting through its software driver control.
●The Status Readback output from one module can be connected to the Enable of the next module in
the series chain. Disconnection of the user connector or if the link between the interlock pins is open-
circuit will result in the relays of all the modules further returning to their default unpowered state. As in
the previous cases when the user connection is re-established the software driver will need to restart
the system.
It should be emphasized that if the Enable pin of the module is set low, even temporarily, the module will not
automatically turn back on when the Enable returns high. The software driver must be used to turn the channels
back on.
If required, spare / replacement hardware interlock connector(s) can be purchased, please refer to Support Products
in Section 1 for details.
