a matrix with multiple mainframes is tO connect up to five units in a masterlslsve configura- tion. 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 ad- dressed 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 bet- ween 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. 27 chnology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.

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 pro- cedure can be performed over the IEEE-488 bus. Figure 3 shows the setup data paths for these steps. Figure 3.

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 us- ing 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 chnology Group - Quality Instrumentation ...

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 DISPLAY- MEMORY 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 chnology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www

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. 33 chnology Group - Quality Instrumentation ...
