DB9 Interfaces
The interface box, the Quadcable, and the Octacable all
feature DB9 ports, labeled from 1 to 8,which correspond to
the jumpers on the card.
Note: Although the RocketPort 485 card supports eight
ports, if you have a quadcable connected, you will
only have four ports available for use.
DB9 Pinouts
Each connector is a DB9 male, with pins numbered as
shown below:
Pin 1
Pin 6
Depending on jumper configuration, the pins carry the
following values:
Pin

RxD

TxD
4
DTR

Signal ground

Ports 1 and 2 can be either RS-232 or RS-485, while
Ports 3 through 8 are RS-232 only. All RS-232 control
signals are present in RS-485 mode, but not used.
** Ports 3 - 8 can be configured to carry +5V on Pin 9.
Do not use the +5V power option with the Quad/
Octacable. Using this feature with interfaces
other than the DB9 box may result in
unacceptable voltage loss.
Caution
Building DB9 Female Loopback Plugs or Cables
To perform loopback testing of DB9
ports in RS-232 mode, use a female
DB9 connector with the following
pins wired together:
•
Pins 2 to 3
•
Pins 7 to 8
•
Pins 1 to 4 to 6
Note: If you use the +5V Power feature, either remove the
jumper or disconnect the power supply cable before
running the diagnostics. If you do not do so, the
diagnostics fail.

RJ45 Interfaces
The Octacable RJ45 fanouts use RJ45 connectors.

Ports 1 and 2 can be either RS-232 or RS-485, while
Ports 3 through 8 are RS-232 only. All RS-232 modem
control signals are present in RS-485 mode, but not
used.
While the RocketPort 485 card can be configured
to supply +5V, this voltage is not accessible on
the RJ45 connector. Therefore this option should
not be used with the Octacable RJ45.
