AXC-SMPSMPTE Time Code

Audiovisual events, multi-imagepresentations, andmulti-scenelighting events require a standardized method of synchronizing material for presentations and performances. The Society of Motion Picture and Television Engineers (SMPTE) has formulated anindustry-widestandard by a digital encoding/decoding process. TheAXC-SMPSMPTE Time Code Card can receive time code from any audio source such as videotape, audioreel-to-reel, and cassette decks, allowing precise synchronization of Axcess functions and other events.

Sends the current outgoing time to the Master Card as a

 

string in the format "hh:mm:ss.ff".

Master Card.

’TFRAME ON (-<rate>)’

 

Variables:

 

rate = rate 1- 255 in tenth seconds

 

 

TFRAME OFF

Cancels a TFrame On command.

 

Syntax:

 

’TFRAME OFF’

 

 

RXON

Only sets (internally) bit 3 of INPUT STATUS.

 

 

RXOFF

Only clears (internally) bit 3 of INPUT STATUS.

 

 

Programming

The AXC-SMPuses the Axcess programming language. For more information, refer to theAxcess Programming Language instruction manual.

Example:

 

’TIME 2-01:06:05.15’

 

Sends a PUSH of channel 2 when time equals 1 hour, 6 min-

 

utes, 5 seconds, and frame 15.

 

 

CLEAR

Clears all Time commands.

 

 

FRAME

Commands the card to send the current incoming time to the

 

Master Card as a string in the format "hh:mm:ss.ff" which rep-

 

resents hours, minutes, seconds, and frames, respectively.
