Cabling Connections
Cabling specifications for each adapter type (DCP286 i -SBC, DCP386 i and
DCP486 e) are found in the following section. Cabling differences will be
noticed when connecting a DTE port to a DCE device (normally a straight
through cable), and when connecting a DTE port to a DTE device (normally
a null modem cable). Factory setting on all cabling is DTE.

DCP286i-SBC Adapter Cables
The DCP286 i -SBC adapter is shipped with two standard adapter cables
which convert the Micro-D25 male output to a standard DB25 output. Install
the adapter cable for the environment in which you are working:
−
RS232, Emulex part no. PT1011208-01
−
V.35, Emulex part no. PT1011213-01
DCP386i/486e Daughterboard Cabling
This section discusses the default cable connections between the 8-port
daughterboard on the DCP386
i and DCP486 e adapters and external devices.
RS-232 Cabling
The serial ports on the 8-port daughterboard are connected to external
devices via an 8-port breakout cable, also known as an Octopus cable. Each
output provides a standard 25-pin male RS-232C connector for attachment to
external devices.
NOTE: All connections to the board should be made using
shielded cables to reduce radio frequency
interference.
