number Description
4.4 Analog backplane
The Model 7001 has a three-pole analog backplane that
allows the rows or banks of a Model 701X series card
installed in one slot to be connected to the rows or
banks of a second Model 701X series card installed in
the other slot. The three-pole analog backplane of the
mainframe is shown in Figure 4-4.
For example, if the backplane jumpers of two Model
7012 matrix cards are installed, the rows of the two
cards are connected together by simply installing them
in the mainframe. The result is a single 4 × 20 matrix. If
the backplane jumpers on one or both of the matrix
cards were removed, the two cards would be electrical-
ly isolated from each other resulting in two separate 4
×
10 matrices. Figure 4-5 shows how the Model 7012
matrix card is connected to the analog backplane. Note
that the matrix card has only two poles (High and
Low). The third pole (Guard) of the analog backplane
is not used.
Keep in mind that not all Model 701X series cards can
be connected to the analog backplane of the Model
7001. The Model 7013 Relay Switch Card is made up of
20 individual IN/OUT relay channels. Each channel is
electrically isolated from each other. A Model 7013 in-
stalled in a slot of the mainframe will be electrically iso-
lated from any other card installed in the other slot.
NOTE
The Model 7001 does not provide an
analog backplane for non-701X series
cards (such as the Model 7052). A non-
701X series card installed in a slot of
the mainframe will be electrically iso-
lated from any other card installed in
the other slot. The only way to connect
one of these cards to a card in the other
slot is to wire them together.
