RS-422 Control— Two RS-422 auxiliary ports are provided:
Port 1 is a slave port that allows 2Xtreme to be controlled by an
external edit controller.
Port 2 is a master port used to control a VTR (Sony protocol).

GPI— The GPI (General Purpose Interface) port allows simple
“trigger” control of internal and external functions. Four input
GPIs and four output GPIs are standard:
• Input GPIs trigger programmed macros 1 through 4
• Output GPIs are initiated from the 2Xtreme keyboard

SCSI port— When used as a SCSI “master,” the Ultra SCSI-3
port provides backup and restore capability to or from a
streaming tape drive.
When used as a SCSI “target,” the SCSI interface allows fast pic-
ture transfer and control with SGI Workstations, or with a PC or
Macintosh computer (requires optional software such as Animaq
Digital from Diaquest).
The Ultra SCSI-3 port is standard. For intensive SCSI transfers
or longer cable runs, the differential SCSI board option is recom-
mended.

Ethernet port— The Ethernet port facilitates external control of
WSD/Xtreme as well as image transfer. Remote Shell and
Remote Login protocols are available. An extensive command
menu is provided.
External control of 2Xtreme is well documented in later chapters
of this manual.
