SNAP-RCK-B2M Rack Adapter Installation
Introduction
SNAP PAC racks are designed to be used with SNAP PAC
brains and rack-mounted controllers. However, if you
have an older I/O processor that you need to use with a
SNAP PAC rack, the SNAP-RCK-B2M rack adapter makes it
possible. The adapter can also be used with SNAP M-
series racks to accommodate processors that would
normally be used on a B-series rack.
The adapter works with the following part numbers:
Important Notes
Change in height: The adapter adds 0.595 inches
(1.511 cm) to the overall height of the unit.
Change in connector location: After installation of the
adapter, the brain or controller’s position will be reversed
on the rack (as well as being higher in relation to the
rack), and letters on the lid will be upside down. Make
sure that cables can still reach the connectors on the
processor.
No new features: The adapter does not change the
capabilities of the brain. For example, four-channel
digital modules still cannot be used in module positions
8 and higher.
Installing the Adapter
Requirements
Part number SNAP-RCK-B2M includes the following
pieces:
•Lock washer
•6-32 hex standoff
•Replacement baseplate
•Adapter
You will also need a medium-sized Phillips screwdriver
to install the adapter.
Installation Steps
1. Remove all SNAP-RCK-B2M pieces from their
packaging.
2. Turn off power to the rack.
3. If there is already a processor on the rack,
disconnect any cables connected to it. Loosen the
screw holding the processor on the rack and
remove the processor. Set it aside.
4. Turn the replacement processor (brain or controller)
upside down. Remove the four small screws
holding the black baseplate on the processor, and
remove the baseplate. Keep the screws.
5. Hold the replacement baseplate so that its
indentation is facing away from the brain (see the
following photo).
6. Align the brain’s hold-down screw with the center
hole in the replacement baseplate. Using the same
four screws, attach the replacement baseplate to
the new processor.
7. On the rack, set the lock washer over the hole next
to the processor’s connector, and then screw the 6-
32 hex standoff into the hole. Tighten the standoff
just to the position where two of the hex points are
parallel with the connector, as shown in the photo
on the following page.

8. Holding the rack adapter with its part number visible
on the top and the black connectors aligned
underneath, set it in position on the rack.
If it does not go on easily, make sure the hex nut’s
points are properly aligned, parallel with the proces-
sor connector.
9. Align the processor’s blue connector with the mating
connector on the rack adapter, and make sure the
indentation in the baseplate aligns with the silver pins
on the adapter.
The processor’s position is now reversed on the rack
(that is, letters on the processor’s lid are upside down).
10. Seat the processor onto the connector and use the
hold-down screw to secure the brain in position. Do
not overtighten.
11. Replace cables and restore power to the rack.
If the replacement processor does not have an IP address,
follow instructions in the PAC Manager User’s Guide to
assign it.
