FUNCTIONAL DESCRIPTION
A functional block diagram is provided in Figure 2.1. The Switched Guard Module is powered by +5V and +3.3V
inputs via Compact PCI connector J1. The interface to the user test equipment is via front panel mounted male
26-pin MS-M multi-way RF connectors, two for the 40-121-001/011 (J2 and J3) or one for the 40-121-002/012
(J2). The module comprises a PCB populated with 26 or 13 double pole reed relays arranged as SPST with
switched guard, or 32 or 16 double pole reed relays arranged as 16 or 8 two channel multiplexers with switched
guard. Each signal path utilizes one reed relay - one pole switches the signal, the other pole switches the guard.
The relays are energised with control signals from relay drivers U10 & U11 via digital isolator U9. The isolator is
driven by PCI bridge U3. Module conguration is determined by data stored in EEPROM U6. PCI Bridge U3 is
congured by EEPROM U8.

2. The chassis must be grounded.
Electrostatic discharge can damage the components on the module. To avoid such damage in handling the
board refer to page VII.
Ensure that there is adequate ventilation.
The module should be installed in accordance with the following procedure:
1. Ensure that the system is turned OFF but still connected to mains so that it remains grounded.
2. Choose an appropriate slot in the rack.
3. Remove the blanking plate for the chosen slot.
4. Ensure that the injector/ejector handle is in its downward position. Align the module with the card guides on
the top and bottom of the slot.
Do not raise the injector/ejector handle whilst inserting the module as the module will not insert properly.
5. Hold the handle whilst slowly sliding the module into the card guides until the handle catches on the injector/
ejector rail (refer to Figure 3.1).
6. Raise the injector/ejector handle until the module rmly seats into the backplane. The front panel of the
module should be ush with the front panel of the chassis.
7. Secure the front panel of the module using both screws to the chassis front panel mounting rails.
8. In a system employing a remote control interface to connect an external controller to a PXI chassis or to link
multiple chassis, power-up the system as follows:
a. For a system comprising an external controller and one chassis, power up the chassis before powering up
the external controller.
b. For a system comprising more than one chassis, turn ON the last chassis in the system followed by the
penultimate, etc, and nally turn ON the external controller or chassis containing the system controller.
9. For Pickering Interfaces modular LXI installation there is no requirement to use any particular power up
sequence.
