SAFETY PRECAUTIONS
2. Inspect the connecting cables and test leads for possi~
ble wear, cracks, or breaks before each use.
3. For maximum safety. do not touch the test cables or any
iktrumenfs while power is applied to the circuit under
test. Turn off the power and discharge any capacitors
before connecting or disconnecting cables from rhe
InmiX car*.
5. Da not exceed the maximum allowable input of the
matrix cards. as defined in the specifications and operas
tion sections of their manual.

MASTER/SLAVE SYSTEMS
A method of expanding a matrix with multiple mainframes
is tO connect up to five units in a masterlslsve configuration. This is done by connecting the rows of like cards in
separate units and by connecting the units in a closed loop
of OIN cables for communication and canfrof. A
masterislave system configuration appears as one unit with
expanded card capacity. That is. only the master unit is addressed by the IEEE-488 bus CO”~,O,,B, and controlled from
the front panel.
A mesterhlsve configuration extends matrix rows yielding
a long, narrow matrix. Figure 2 shows the connections between two units having Model 7071 cards. With five units.
the maximum matrix size is 8 rows by 360 columns. Table
2 shows the column assignments for the maXimm
configuration.
If the mainframes of a master/slave configuration contain
different card models, group like csrds 8s much as possi~
ble. This will reduce the need to extend the analog buses
with exfernsl cables.

BASIC SWITCHING OPERATION
The following paragraphs will take you through a simple,
general, step-by-step procedure to edit a matrix setup, store
it in memory. and send the setup to the relays. Althwgh
ihe steps are described with front panel operations. the procedure can be performed over the IEEE-488 bus.
Figure 3 shows the setup data paths for these steps.
Figure 3. Setup Data Transfers
30
Selecting Make/Break and Break/Make ROWS
Select make-before-break, break-before-make. or don’t care
operation for the rows. The selections will be in effect for
alI relay switching. even if a stored setup is not used. IAs
a general rule, use makeibreak operation for current murces
and breakimake for voltage sources.,
“se the data entry keys to select a mw, then press
MAKE/BREAK or SREAK,MAKE fO toggle the state. lselec~
ting one state for a row de-selects it for th8 other.1 This
operation can also be performed with the light pen by using if to turn on/off the MAKWSREAK and SREAK,MAKt
LEDS.
Modifying a Relay Setup
Step 1: S&et a Stowd Setup
If you want to modify set”,, #I, just press the MEMORY
key. The MEMORY indicator light will light. To select another
setup fup fo location 1001. use the numeric data entry keys
(leading zeros are not necessaryl. then press the MEMORY
key.
Step 2: Modify the Displayed Setup
Use the data entry keys to select a crosspoint address IA1
fhrwgh H721. then press the OPEN or CLOSE key
Keystrokes will be shown an the alphanumeric display and
the CROSSPOINT DISPLAY MODIFIED indicator will light.
31
If You have the optional light pen. toggle the state of a crosspoint LED by holding the light pen perpendicular to and
touching the front panel overlaY and pressing the light pen
button.
Continue editing with the front pane, key or light pen until
the ~ros~point display shows the desired configuration.
Storing Setup and Sending to Relays
Step 1: Storing Setup in Memory
To store the modified setup at the location shown in the
MEMORY STEP field, just press the COPY DISPLAYMEMORY KEY. This action wewrites the old setup data
at that location with the newly modified setup.
To select a different memory location, key in a valid local
tion number, then press the COPY DISPLAY-MEMORY key
The MEMORY STEP field is se, to the new location.
Step 2.4: Sending Setup to Relays
To make the newly modified setup the current relay setup,
just press the COPY DISPLAY-RELAYS key. The relay states
will be changed to reflect the modified setup data. If the
MEMORY LED is lit. the RELAY STEP field will be set equal
to the MEMORY STEP field. In effect. this copies a setup
from memory to the relays.
32
Step 28: Triggering Setup to Relays
If you modified setup #I and restored it to memory at the
same location. a single trigger will copy the setup to the
relays. Do this by pressing the trigger SOURCE key. scrolls
ing to the “TRIG ON KEY” display and pressing ENTER.
Then press the trigger ENABLE key Pressing the trigger
MANUAL key will copy setup #I to the relays and set the
RELAY STEP field to 001.
