MODULAR FIBER CAMPUS DRIVER, MFCD PLUS
2. Hold the module with the faceplate toward you and align the module with
the guide slots in the rear panel of the Campus Driver.
3. While keeping the module’s faceplate parallel with the Campus Driver rear
panel, slide the module straight in, so that the card-edge contacts line up with
the socket inside the chassis.
NOTE
The card-edge connector should meet the socket when the Module is
almost all the way into the chassis. If you encounter a lot of resistance,
remove the module and repeat steps 2 & 3.
4. With the card-edge contacts aligned with the socket, firmly seat the module by
using your thumbs to apply pressure directly to the right and left edges of the
module faceplate. Applying moderate and even pressure should be sufficient
to seat the module. You should hear it “click” into place.
5. To secure the module in place, push the thumbscrews into the chassis and
turn the screws clockwise to tighten.

ONNECTION TO A
“DTE” D
EVICE
The serial port on most interface modules (all except the X.21 module) is hard-
wired as DCE. Therefore these modules “want” to plug into a DTE such as a
terminal, PC, or host. When making the connection to your DTE device, use a
straight-through cable of the shortest possible length—we recommend 6 feet
(1.8 m) or less. When purchasing or constructing an interface cable, please refer
to the pin diagrams in the
Appendix
as a guide.
4.2.3 C
ONNECTION TO A
“DCE” D
EVICE
The serial port on most interface modules is hard-wired as a DCE (all except the
X.21 module). Therefore you must use a null-modem cable when connecting to a
modem, multiplexor, or other DCE device. This cable should be of the shortest
possible length—we recommend 6 feet (1.8 m) or less. When purchasing or
constructing a null-modem cable, use the pin diagrams in the
Appendix
as a guide.
NOTE
Pin-out requirements for null-modem applications vary widely between
manufacturers. If you have any questions about a specific application,
contact Black Box Technical Support at 724-746-5500.
