J6A2 Jumper Block For Dcd Signal; J6A2 Jumper Block For Dsr Signal; Rear Com2 Port Adapter Pin-Out - Intel SCB2 - Server Board Motherboard Product Manual

NOTE
By default, as configured in the factory, the SCB2 baseboard will have the
rear RJ45 serial port configured to support a DSR signal.
For serial concentrators that require a DCD signal, the J6A2 jumper block must be configured as
follows: The DCD jumper in position 2 and 3 and the DSR jumper in position 2 and 3. Pin 1 on the
jumper is denoted by an arrow directly next to the jumper block. See Figure 3 on page 15 for the
jumper block pin-out of this configuration.
For serial concentrators that require a DSR signal, the J6A2 jumper block must be configured as
follows: The DSR jumper in position 1 and 2 and the DCD jumper in position 1 and 2. Pin 1 on the
jumper is denoted by an arrow directly next to the jumper block. See Figure 4.
For those server applications that require a DB9 type of serial connector, an 8-pin RJ45-to-DB9
adapter must be used. The following table defines the pin-out required for the adapter to provide
RS232 support.
