Relay Matrix Switches Description
The E1468A and E1469A Relay Matrix Switch modules are VXIbus C-Size
register-based modules and operate with an E1406 Command Module.
EachRelayMatrixSwitchconsistsofacomponent module with 64 two-wire
relays and a terminal module for connecting user inputs. The component
module (E1468-66202) is the same for the E1468A and E1469A. The
terminal module for the E1468A (E1468-90011) and the terminal module
for the E1469A (E1469-80011) are different for the two Relay Matrix Switch
modules.
E1468A Switch
Description The E1468A Relay Matrix Switch module provides an 8 x 8 two-wire
crosspoint matrix. Multiple modules can be wired together creating 8 x 16
(two modules), 16 x 16 (four modules), 8 x 24 (three modules), or larger
matrices. Figure 1-1 shows a simplified schematic of the E1468A
component module and terminal module.
E1469A Switch
Description The E1469A Relay Matrix Switch module provides a 4 x 16 two-wire
crosspoint matrix. Multiple modules can be wired together creating 4 x 32
(two modules), 8 x 16 (two modules), 4 x 48 (three modules), or larger
matrices. Figure 1-2 shows a simplified schematic of the E1469A
component module and terminal module.
E1468A/E1469A
Connector Pin-Outs Each Relay Matrix Switch module consists of a component module and a
terminal module. Figure 1-3 illustrates the front panel of an E1468A/E1469A
component module and the connector pin-out. The terminal module makes
the row and column connection to form the matrix configuration (see Figures
1-1 and 1-2).

Configuring the Relay Matrix Switches
This section gives guidelines to configure the Relay Matrix Switch modules,
including:
•Warnings and Cautions
•Setting the Logical Address Switch
•Setting the Status Register Switch
•Setting the Interrupt Priority
•Installing Relay Matrix Switches in a Mainframe
Warnings and
Cautions
WARNING SHOCK HAZARD. Only service-trained personnel who are
aware of the hazards involved should install, remove, or
configure the Relay Matrix Switch modules. Before removing
any installed module, disconnect AC power from the VXI
mainframe and from any devices connected to the Relay
Matrix Wwitch modules.
WARNING CHANNEL WIRING INSULATION. All channels that have a
common connection must be insulated so that the user is
protected from electrical shock in the event that two or more
channels are connected together.
CAUTION Maximum Inputs. The maximum voltage that can be applied to any terminal is 220
Vdc/250 Vrms. The maximum current that can be applied to any terminal is 1A at 30
Vdc/Vrms, or 0.3A at 220 Vdc/250 Vrms. The maximum power that can be applied
to any terminal is 40 VA.
CAUTION Static Electricity. Static electricity is a major cause of component failure.
To prevent damage to the electrical components in a Relay Matrix Switch module,
observe anti-static techniques when removing or installing the module or when
workingonthemodule.

16 Getting Started Chapter 1
Setting the Logical
Address Switch The logical address switch (LADDR) factory setting is 112. Valid addresses
are from 1 to 255. See Figure 1-4 for switch information. The address switch
value must be a multiple of8 ifthe module is the firstmodulein a "switchbox"
used with a VXIbus command module using SCPI commands.
Setting the Status
Register Switch Four bits of the status register switch (bits 10-13) define whether the relay
matrix switch module is an E1468A or E1469A. These bits are set
automatically when the terminal module is installed.
To ensure proper operation, even without the terminal module, set the
status register switch as shown in Figure 1-5. However, if the status register
switch is set for the E1468A, but the terminal module is an E1469A (or
vice-versa), the interface will not be able to correctly identify and an error
will occur.

Chapter 1
Setting the Interrupt
Priority The E1468A/E1469A Relay Matrix Switch modules generate an interrupt
after a channel has been closed. These interrupts are sent to, and
acknowledgments are received from, the command module (such as an
E1406) through the VXIbus backplane interrupt lines.
For most applications where the relay matrix switch module is installed
in a C-Size VXI mainframe, the interrupt priority jumper does not have to be
moved. This is because the VXIbus interrupt lines have the same priority
and interrupt priority is established by installing the modules in slots
numerically closest to the E1406 Command Module. Thus, slot 1 has a
higher priority than slot 2, slot 2 has a higher priority than slot 3, etc..
See Figure 1-6 to change the interrupt priority. You can select eight different
interrupt priority levels. Level 1 is the lowest priorityand level 7 is the highest
priority. Level X disables the interrupt.
The module's factory setting is level 1. To change the priority level, remove
the four-pin jumper from the old priority location and reinstall the jumper in
the new priority location. If the four-pin jumper is not used, the two jumper
locations must have the same interrupt priority level selected.
NOTE The interrupt priority jumper must be installed in position 1 when using the
E1406 Command Module. Level X interrupt priority should not be used
under normal operating conditions. Changing the interrupt priority level
jumper is not recommended.

modules, including:
•Wiring the Terminal Module
•Creating Larger Matrixes
•Attaching a Terminal Module to the Relay Switch Module

Modules Guidelines to wire the E1468A and E1469A terminal modules follow.

Connectors Figure 1-8 shows the E1468A terminal module connectors and associated
row/column designators. Shielding jumpers JM1 - JM10 are shown. See
"Creating Larger Matrices" for information on using the expansion
connectors J1 - J4 and for shield wiring details.
NOTE Jumpers JM1 - JM10 on the E1468A terminal module connect row/column
shields to earth ground through the VXIbus backplane. You may want to
remove one or more of these jumpers to reduce common mode noise.
