Appendix B. Cable Descriptions

This appendix describes cables that can be used with an Origin200 system, including

Serial Cables

The following sections contain descriptions of various types of serial cables that you can use to attach devices to Origin200 systems.

Printer/Character (ASCII) Terminal Cable

The cable described in this section attaches a printer or a character (ASCII) terminal to the Origin200 server. The server ships with a cable of this type, and you can purchase an additional or replacement cable from SGI or your local service provider.

Table B-1 shows the cable connector pin assignments.

Modem Cable (Full-Handshake)

This modem cable provides request-to-send (RTS) and clear-to-send (CTS) connections, and is appropriate for a modem with RTS/CTS flow control. This cable also works with other serial devices (except printers and terminals) that do not need RTS/CTS flow control, and you can use it with a null modem adapter to attach printers and character terminals. You can purchase this full-handshake serial cable from SGI or from your local service provider.

AUX Port Cables

The Origin200 AUX port is an 8-pin mini-DIN connector that uses the standard RS-232 serial protocol. The next sections describe cables you can use to connect a terminal or modem to the AUX port. Table B-7 summarizes the part numbers of the SGI cables described in this section.
