Building RJ45 Loopback Plugs or Cables
To perform loopback testing of RJ45
ports in RS-232 mode, obtain or
create an RJ45 connector with the
following pins wired together:
• Pins 4 to 5
• Pins 1 to 8
• Pins 2 to 6 to 7
To test RJ45 ports in RS-485 mode,
obtain two RJ45 connectors and
create the cable shown below:
Setting the DIP Switches
The RocketPort ISA card uses a DIP switch to set the base
I/O address range. The default value is 180 (hex). If you
are installing more than one RocketPort card, or if you
experience an I/O address conflict with another device, use
the DIP switches to change the I/O address.
For example, if you install two RocketPort cards and are
using the default address range:
The following table lists possible DIP switch settings. We
recommend starting with the default settings and making
changes only if the default values produce conflicts.
Notes:
1. If installing a single RocketPort ISA card, set the DIP
switches as shown in the table.
2. If installing two ISA cards, set the DIP switches on the
second card the same as the switches on the first card,
EXCEPT SWITCH 5 OFF.
3. If installing three ISA cards, follow Note 2 for the second
card, then set the DIP switches on the third card the
same as the switches on the first card, EXCEPT
SWITCH 6 OFF.
4. If installing four ISA cards, follow Notes 2 and 3 for the
second and third cards, then set the DIP switches on the
fourth card the same as on the first card, EXCEPT
SWITCHES 5 AND 6 OFF.
