Figure 5. J5A2 Jumper Block for DCD Signal
For serial concentrators that require a DSR signal (Default), the J5A2 jumper block must be
configured as follows: The Serial Port jumper in position 3 and 4. Pin 1 on the jumper is
denoted by an arrow directly next to the jumper block.
Figure 6. J5A2 Jumper Block for DSR Signal
For those server applications that require a DB9 serial connector, an 8-pin RJ45-to-DB9 adapter
must be used. The following table provides the pin-out required for the adapter to provide
RS232 support. A standard DH-10 to DB 9 cable and 8-pin RJ45 to DB9 DCD & DSR adapters
are available from Intel in the Serial Accessory Kit.

Note: The RJ45-to-DB9 adapter should match the configuration of the serial device used. One
of two pin-out configurations is used depending on whether the serial device requires a DSR or
DCD signal. The final adapter configuration should also match the desired pin-out of the RJ45
connector, as it can also be configured to support either DSR or DCD.
