Appendix A. Connector Pinout AssignmentsThis appendix describes the pinouts of the following external connectors on an Origin200 server:
For a description of cables that can be used with the serial and diagnostic ports, see Appendix B, “Cable Descriptions.”
Table A-1 shows the connector pin assignments for the serial ports in RS-232 mode.

The AUX port is used to communicate with the module system controller (MSC). You can attach a serial (ASCII) terminal to the port, or attach a modem for remote access. Table A-5 shows the connector pin assignments for the port.

 | Note: These pin assignments are the same as the ones for the serial ports on the Silicon Graphics Indy and Indigo2 workstations and the CHALLENGE S server. Cables that are appropriate for the serial ports of those systems can be used with the AUX port as well.

The external interrupt interface uses two 1/8-inch (3.5 mm) stereo jacks: one to generate interrupts and one to receive interrupts. The jacks are located on the back of the Origin200 server and are wired as indicated in Table A-6:.
Table A-6. External Interrupt Port Conductors

| Function
|
|---|
Tip
| Interrupt (active low)
| Ring
| +5 V
| Sleeve
| Chassis ground and cable shield
|
When constructing interrupt cables, use the two-conductor shielded cable type, wired straight through (tip-to-tip, ring-to-ring, sleeve-to-sleeve using the shield). For more information on the external interrupt interface, see the ei(7) man page.
