This appendix describes various cables that can be used with an Origin200 system, including:
serial
AUX port
The following sections contain descriptions of various types of serial cables that you can use to attach devices to Origin200.
Use this cable to attach a printer or a character (ASCII) terminal to Origin200. The server ships with a cable of this type, and you can purchase an additional or replacement cable from Silicon Graphics or your local service provider.
Table B-1 shows the cable connector pin assignments.

This 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 will also work 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 Silicon Graphics or from your local service provider.
Table B-2 shows the cable connector pin assignments.

The Origin200 AUX port is an 8-pin, mini-DIN connector and 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.
Use this cable to connect the Origin200 AUX port to a terminal. Note that this cable is identical to the one used to attach a terminal to a Silicon Graphics Indy, Indigo, or Indigo2 workstation and CHALLENGE S server. The cable is available as Silicon Graphics part number 018-8114-001.
