Switching card considerations

Before operating a switch system, familiarize yourself with
the following switching card information.

3.8.1 Switching card simulators

Instrument operation can be performed without any switch-
ing cards installed in the Model 7002 by using the switching
card simulators. By selecting the appropriate switching card
simulator, the Model 7002 will operate as if a 40-channel
switching card or a 4 × 10 matrix card were installed. This is
useful if you want to develop a test program without having
a card installed.
When a slot is assigned the model number 9990, the main-
frame will operate as if a 40-channel switching card is in-
stalled. When a slot is assigned model number 9991, the
mainframe will operate as if a 4 × 10 matrix card is installed.
These simulator model numbers are assigned by setting card
TYPE in the CARD CONFIG MENU (see paragraph 3.8.3).
NOTE
A simulator cannot be assigned to a slot
that already has a Model 701X series card
installed in it.

3.8.2 Installing switching cards

The procedure to install switching cards in the mainframe is
explained in Section 2 of this manual. If using a switching
card simulator as explained in the previous paragraph, leave
the appropriate slot empty.

3.8.3 Card type

On power-up, the Model 7002 senses 701X type cards that
are installed and automatically configures itself for proper
operation. If a non-701X type card is installed in a slot, then
you will have to assign the model number of the card to that
slot.
Perform the following steps to check or change card assign-
ments for the mainframe slots:
1. Press CARD CONFIGURATION to display the CARD
CONFIG MENU.
2. Place the cursor on TYPE and press ENTER to select
SET CARD TYPE. The card type for the currently se-
lected slot will be displayed. For example:
SET CARD TYPE
SLOT-#1 #2 #3 #4 #5
In the above example, if #3 flashes, it indicates that the
Model 7012 is installed in slot 3.
3. To check card assignment types for the other slots, sim-
ply use the cursor keys (
on the slot number. Card type assignments are defined as
follows:
NONE = Slot is assigned as an empty slot (channel
LEDs disabled).
701X = High density card installed (i.e. Model 7011,
7012, 7013, 7014).
9990 = Slot is assigned to operate as a simulator (40-
channel multiplexer).
9991 = Slot is assigned to operate as a simulator (4×10
matrix).
7052 thru 7402 = Slot is assigned to operate for the se-
lected model number.
4. Perform the following steps to change the card type as-
signment for a slot:
a. Place the cursor on the desired slot number and
press ENTER. For example:
SLOT 5 CARD: NONE
The above message indicates that slot 5 is assigned
as an empty slot.
b. Use the cursor keys to display the appropriate as-
signment. For example, if you have a Model 7052
installed in slot 5, assign 7052 to slot 5 as shown:
SLOT 5 CARD: 7052
