AMX AXC-SMP Quick Start Manual

Audiovisual events, multi-image presentations, and multi-scene lighting
events require a standardized method of synchronizing material for presen-
tations and performances. The Society of Motion Picture and Television
Engineers (SMPTE) has formulated an industry-wide standard by a digital
encoding/decoding process. The AXC-SMP SMPTE Time Code Card can
receive time code from any audio source such as videotape, audio reel-to-
reel, and cassette decks, allowing precise synchronization of Axcess func-
tions and other events.

Programming
The AXC-SMP uses the Axcess programming language. For more informa-
tion, refer to the Axcess Programming Language instruction manual.
The table below lists the Send_Commands available to the AXC-SMP .
Send_Commands
TIME If another TIME command is received with the same Push
channel, the new time will replace the previous one.
Programs card to
Syntax:
Push the specified
channel upon match
'TIME <PUSH channel>-<hh:mm:ss.ff>'
of the specified
Variables:
incoming time.
hh = Hours
mm = Minutes
ss = Seconds
ff = Frames
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.
FRAME ON Default with no rate specified is 1 second.
Syntax:
Commands the card
to send the current
'FRAME ON (-<rate>)'
incoming time to the
Variables:
master as a string at

the optional peri-
Example:
odic time rate.
'FRAME ON-5'
Sends the incoming time every 0.5 second.
FRAME OFF Cancels a FRAME ON command.
SEND ON Begins generating at the optionally specified time. If no time is
specified, then the first SEND ON command after power-up

will start at time "00:00:00.00"; otherwise, time continues from
outgoing time code.
where the last SEND OFF command stopped it.
Syntax:
'SEND ON (-<hh:mm:ss.ff>)'

Send_Commands (Cont.)
SEND OFF Discontinues or pauses generating outgoing time code.
Syntax:
'SEND OFF'
TFRAME Sends the current outgoing time to the Master Card as a
string in the format "hh:mm:ss.ff".
Syntax:
'TFRAME'
TFRAME ON Sends it as a string at the optional periodic time rate; the
default with no rate specified is one second.
Sends the current

Master Card.
'TFRAME ON (-<rate>)'
Variables:

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.
