The lockout key configuration for the 1260-64 is slightly different
from that of the other 1260 modules because the 1260-64
occupies two VXI slots. Lockout key mounting holes are present
in the front panel for each of the occupied VXI slots.
If the module is not the leftmost nor the rightmost module in the
group, lockout key "A" (Racal Instruments P/N 455540) should
be installed in the location corresponding
to the module's left slot. Lockout key "C" (Racal Instruments
P/N 455541) should be installed in the location corresponding to
the module's right slot.
If the module is the leftmost module in the group, lockout key
"C" should be installed in the location corresponding to the
module's right slot.
if the module is the rightmost module in the group, lockout key
"A" should be installed in the location corresponding to the
module's left slot.
Installation of the 1260-64 Switching Module into a VXI
mainframe, including the setting of DIP switches, is described in
the Installation section of the 1260-Series VXI Switching Cards
Manual. The ID byte DIP switches should be set as follows:
1260-64A
5=OFF 6=OFF
1260-64B
5=ON
1 260-64C
5=OFF 6=ON
Note that incorrect setting of the ID byte DIP switches will cause
an incorrect module ID to be reported to the user in response to
a PDATAOUT command. All other module functionality is
unaffected by the setting of the ID byte switches.
If two banks of DC relays are to be used, various internal
jumpers must be installed. Examples of four possible
configurations are shown in Figures 4-3 through 4-6. The card is
shipped from the factory without any jumpers installed.
To access the jumpers, remove the right side cover from the
module. The jumpers are located on the large PCB Assembly.
There are two banks of relays. Each bank is configured
independently, and the two configurations do not have to match.
The banks are designated Bank A and Bank B.
