Mating the Adapter to the Plug-In
ij CAUTION
Do not exert excessive turning pressure on
the clamp adjust knob
(Figure 2-7)
or
damage to the clamp mechanism may result»
Mate the Plug-In Interface Connector PI of the 11869A Adapter with
the corresponding connector on the RF Plug-In. Make sure that the
top and bottom frames of the Adapter and the RF Plug-In are
aligned.
If an Option 004 rear-panel RF output cable or an Option
006 rear panel auxiliary output cable is being installed, connect
the SMA end of the semi-rigid cable to the inside of the
corresponding output connector on the rear panel of the 11869A
Adapter. Rotate the black clamp adjust knobs on the top and bottom
of the 11869A to the TO CONNECT position to retract the clamps and
lock the two units together.
9.
Connecting the BMC Cables
Three BNC interconnect cables are supplied in a separate package
with the 11869A. The blue cable is the FREQ REF cable;
the white
cable is the EXT ALC IN cable;
and the gray cable is the PULSE IN
cable. Lock washers and hex nuts are supplied for all three cables,
as well as two flat plastic insulators for the EXT ALC IN cable.
The purple BNC to SMD cable for the FM Input is factory installed,
with the BNC end held in a restraining clamp.
Push the female BNC connectors of the cables through the
appropriate holes in the 11869A rear panel from the inside, and
secure each with a lock washer and a hex nut on the outside. When
installing the white EXT ALC IN cable, place plastic insulators on
both sides of the hole. Tighten the hex nuts with a 9/16-inch
wrench.
Connect the male BNC connectors of the cables to the corresponding
female BNC connectors on the rear panel of the Plug-In. If the FM
input is to be used, connect the purple cable to the FM connector
of the Plug-In.
10.
Setting the Plug-In Identification Switch
Locate the Plug-In Identification Switch A1S1 on the top panel of
the 11869A Adapter. From the CODES list above the switch, select
the code that corresponds with the Plug-In to be used, and set the
four switch rockers to that code. If the exact model number of the
RF Plug-In is not listed above switch A1S1,
it is a factory
modified Special Plug-In requiring the installation of a special
matching PROM
(see paragraph 2 above). If the Plug-In is a factory
modified Special, encode switch A1S1 to 1111.
