7: Configuring and Using External Devices

This chapter explains installing and conﬁguring these devices in the following sections:

• “Conﬁguring and Using the Sony (P2) Protocol” on page 88

• “Conﬁguring the SGI Media Server to Control a VTR” on page 91

• “Conﬁguring the SGI Media Server for Control by VDCP” on page 93

• “Using House Timecode Readers with the SGI Media Server” on page 98

• “RS-232 and RS-422 Cabling” on page 99

Conﬁguring and Using the Sony (P2) Protocol

The Sony (P2) protocol is partially supported by Video Server Technology (VST) so that

the server can be controlled by standard VTR controllers. The conﬁguration information

makes the server behave similar to a video tape deck.

Note: P2 is an alternate name for the Sony protocol. For the remainder of the chapter, the

term “Sony” represents both Sony and P2.

The following sections describe how to conﬁgure the server to work with the Sony

protocol:

• “Conﬁguring Sony Protocol Control Ports” on page 89

• “Changing the Clip Loaded in a Sony Controlled Logical Unit” on page 91

Caution: Opening a unit owned by a Sony port using MVCP commands (for example,

UOPN) causes unpredictable behavior and is unsupported.

The SGI Media Server does not currently support the entire Sony protocol speciﬁcation.

It does not support the following:

• Video output parameter selection

• Audio output parameter selection

• Audio split editing

• Insert editing for anything less than all video/audio tracks
