Configuring Non-701X Series Cards for

Model 7001/7002 Switch Systems

Introduction

This addendum explains configuring cards originally designed for the Model 705/706
Scanners with newer mainframes, such as the Model 7001/7002 Switch Systems. It
supersedes descriptions in the non-701X card manuals concerning the programming
of pole mode, channels/crosspoints, and settling time.

In general, the Model 7001/7002 mainframes detect (on power-up) Model 701X
series cards that are installed. If using older cards, you must assign a model number
to the appropriate slots.

After Model 7001/7002 mainframes are configured for any non-701X series cards,
relay closures on these cards can be programmed from the front panel or IEEE-488
bus. Switch and multiplexer cards are programmed by slot and channel (S!C), while
matrix cards are programmed by slot, row, and column (S!R!C).

Card configuration

The CARD CONFIG MENU of the Model 7001/7002 Switch Systems configures the
card slots. Press the CARD CONFIGURATION key to display the following:

CARD CONFIG MENU

TYPE #-OF-POLES CARD-PAIR

DELAY READ-I/O-CARD

TYPE

Use TYPE to assign a model number for each non-701X series card installed in the
mainframe. The model number assignment determines the relay settling time and
front panel relay status display. From the CARD CONFIG MENU, perform the fol­lowing steps to assign a model number to a slot:

1. With the and keys, place the cursor on TYPE and press ENTER. The model
number for the presently selected slot is displayed. For example, with a Model
7002 mainframe:

PA-400 Rev. A
September 1993

SET CARD TYPE NONE

SLOT-#1 #2 #3 #4 #5

SLOT-#6 #7 #8 #9 #10

A flashing “#5” would indicate that slot 5 is assigned to be empty (NONE). To
check assignments for other slots, simply use or .

2. Move the cursor to the desired slot number and press ENTER. An example dis­play follows:

SLOT 5 CARD: NONE

3. Assign a model number to the slot. For example, if a Model 7062 is installed in
slot 5, use or to scroll to “7062”.

4. With the model number assignment displayed, press ENTER.

5. When finished, use EXIT to back out of the menu structure. Note that the relay
status display changes to show the channel or crosspoint configuration of the
card.

#-OF-POLES

While installed in Model 7001/7002 mainframes, two of the non-701X series cards
(7056 and 7156) can have their pole configuration changed. The following table
shows the pole configuration for all non-701X cards.

From the CARD CONFIG MENU, perform the following steps to check or change
the pole configuration of a switching card:

1. Place the cursor on #-OF-POLES and press ENTER. The following is displayed
for a Model 7002 mainframe:

SELECT # OF POLES

SLOT-#1 #2 #3 #4 #5

SLOT-#6 #7 #8 #9 #10

2. Move the cursor to the desired slot number and press ENTER. The pole configu­ration for that slot is displayed. For example, if you selected slot 7, the following
is displayed:

# OF POLES SLOT-7

1-POLE 2-POLE 4-POLE

The flashing menu item indicates which pole configuration is presently selected.

3. To retain the present pole configuration, press ENTER or EXIT. To change the
pole configuration, move the cursor to the desired selection and press ENTER.
Note that you cannot select an invalid pole configuration.

4. When finished, use EXIT to back out of the menu structure.

CARD-PAIR

This menu item lets you pair cards so that corresponding channels/crosspoints oper­ate together as a pair. For example, with a Model 7002 mainframe, closing channel 2
of slot 1 also closes channel 2 of slot 6. Card pair can only be enabled for cards that
are similar (multiplexer or matrix) and have the same number of channels.

From the CARD CONFIG MENU, perform the following steps to check or change
card pair:

1. Place the cursor on CARD-PAIR and press ENTER to display the card pair
selections. For example, with a Model 7002 mainframe:

CHOOSE CARD PAIR

1&6 2&7 3&8 4&9 5&10

2. Move the cursor to the desired card pair and press ENTER. If you select card
pair 1&6, the following message is displayed:

SET CARD PAIR 1&6

OFF ON

The flashing menu item indicates the state of card pair for the two cards.

3. To retain the state, press ENTER or EXIT. To change the state, move the cursor
to the desired selection and press ENTER.

4. When finished, use EXIT to back out of the menu structure.

DELAY

This user-programmed delay (1ms to 99999.999s) is the time delay between channel/
crosspoint closures during a scan. It is in addition to the internally set relay settling
time delay.

From the CARD CONFIG MENU, perform the following steps to set a delay:

1. Place the cursor on DELAY and press ENTER to display the following mes­sage:

SET DELAY FOR:

SLOT-#1 #2 #3 #4 #5

SLOT-#6 #7 #8 #9 #10

2. Move the cursor to the desired card slot and press ENTER. If you select slot 6
and it presently is set for a one second delay, the following message is dis­played:

(06) DELAY=00001.000

3. To change the delay period, use and and the numeric keypad to key in a
new value, then press ENTER.

4. When finished, use EXIT to back out of the menu structure.

Additional information on configuring switch cards can be found in “Card configura­tion” in Section 4 of the Model 7001 and 7002 Instruction Manuals.
