Cable Usage Guide
Introduction
Digi Neo and AccelePort® Xp adapters easily expand the number of
EIA-232 ports available on your computer, allowing you to cable addi-
tional peripheral devices, such as modems, terminals or serial printers,
directly to your computer.
This Cable Usage Guide describes the different connector options avail-
able from Digi, and methods in which they may be used.

† DSR (Pin 2 on a 10 pin connector, Pin 1 on an 8 pin
connector) can be swapped with DCD by using the ALTPIN
configuration option. ALTPIN reverses the position of these two
signals in 10 pin connectors and allows DCD to be used instead
of DSR on an 8 pin connector.
Consult the driver documentation for how to do this in your
specific operating system.
Connector Assembly Options and Part Numbers
Various connector assembly options are available for use with Digi Neo
and AccelePort Xp adapters. The tables below provide the Digi part num-
bers for these options.
CAUTION: Many SCSI adapters use the same HD-68 connector type as
the Digi adapters. Do not plug SCSI devices into the Digi connector, and
do not plug Digi peripheral cables into SCSI adapters.
Fan-out Cables and Part Numbers
Use the table below to obtain the part numbers for fan-out cable options:
Fan-out cables are four feet in length, and can be used with adapters sup-
porting four or more ports.
NOTE: For AccelePort 16p adapters, use two 8-port fan-out cables.
Connector Boxes and Part Numbers
Connector boxes are available in the following configurations:
The 4-port and 8-port connector boxes may be placed on the desktop or
floor, or wall-mounted by attaching a bracket (included with the connec-
tor box). The wall-mount bracket can also be used for rack mounting.
NOTE: Two 8-port assemblies may be used with an AccelePort 16p
adapter (for example, two DB-9 boxes, or two different connector types).
Connector Box Interconnect Cable
The 4- and 8-port connector boxes have a 6-foot (1.82m) cable attached
equipped with a high-density HD-68 connector on the end that connects
to the adapter.
The 16-port connector boxes have two 10-foot (3.05m) cables included
with the system. This is a separate cable with HD-68 male connectors on
both ends
HD-68 to DB-78 Adapter and Part Number
If you already have connector assemblies for an AccelePort Xr, Xe, PC/X
or ClassicBoard adapter, you can use them with a Digi Neo or AccelePort
Xp adapter by installing an HD-68M to DB-78F converter assembly:
Connector Box Mounting Options
Installing Brackets on 4- and 8-Port Connector
Boxes
Use this procedure to install the wall-mount bracket on 4- and 8-port con-
nector boxes. Wall-mount brackets are included with the connector
boxes.
1. Remove the two screws from the end of the connector box opposite
the cable connection.
2. Use the screws to attach the wall-mount bracket as shown in the fig-
ure below. The 4-port DB-25 connector box is shown; the procedure
is the same for all 4- and 8-port connector boxes.
Figure 1. Attaching the Wall-mount Bracket to a 4-Port Box
Installing Rack-mount Tabs on 16-Port Connector
Boxes
Use this procedure to install the rack-mount brackets on a 16-port con-
nector box.
1. Remove the front two screws from each end of the connector box
assembly (the assembly may be installed with either face in front).
2. Use the screws to attach the rack-mount tabs as shown in the figure
below (the figure shows an RJ-45 box; the procedure is similar for
DB-25 boxes).
Figure 2. Attaching Rack-mount Tabs to a 16-Port RJ-45 Box
Installing 16-Port DB-25 Connector Boxes on a
Desktop
When a 16-port DB-25 connector box is fully loaded, the weight of the
attached cables may exceed the weight of the connector box itself. This
can cause the box to tip over if placed near the edge of the desktop. To
prevent this, position the connector box sufficiently far from the edge of
the desktop so that the connectors are supported by the desktop.
To add stability to a connector box placed on a desktop, install the rack-
mount tabs as shown in Figure 3.
