Quick Start Guide AXC-SMP SMPTE Time Code Audiovisual events, multi-image presentations, and multi-scene lighting events require a standardized method of synchronizing material for presentations 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-toreel, and cassette decks, allowing precise synchronization of Axcess functions and other events. 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 the current outgoing time to the Master Card. Sends it as a string at the optional periodic time rate; the default with no rate specified is one second. Syntax: Specifications Specifications Power Requirement Indicators Data Output 45 mA @ 12 VDC CR1: transmitting SMPTE data CR2: receiving SMPTE data SMPTE time code (HH:MM:SS:FF) word representing time in hours, minutes, seconds, and frames. 'TFRAME ON (-)' Variables: rate = rate 1- 255 in tenth seconds TFRAME OFF Cancels a TFrame On command. Syntax: 'TFRAME OFF' Pinouts The following table shows the AXC-SMP pinouts. Pinouts Pinout 1 2 3 4 Description GND Line Level SMPTE input GND Line Level SMPTE output RXON RXOFF Only sets (internally) bit 3 of INPUT STATUS. Only clears (internally) bit 3 of INPUT STATUS. Programming The AXC-SMP uses the Axcess programming language. For more information, refer to the Axcess Programming Language instruction manual. The table below lists the Send_Commands available to the AXC-SMP . Send_Commands TIME Programs card to Push the specified channel upon match of the specified incoming time. If another TIME command is received with the same Push channel, the new time will replace the previous one. Syntax: 'TIME -' Variables: 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 minutes, 5 seconds, and frame 15. CLEAR FRAME Clears all Time commands. Commands the card to send the current incoming time to the Master Card as a string in the format "hh:mm:ss.ff" which represents hours, minutes, seconds, and frames, respectively. Default with no rate specified is 1 second. Syntax: FRAME ON Commands the card to send the current incoming time to the master as a string at the optional periodic time rate. 'FRAME ON (-)' Variables: rate = rate 1 - 255 in tenth seconds Example: 'FRAME ON-5' Sends the incoming time every 0.5 second. FRAME OFF SEND ON Begins generating outgoing time code. Cancels a FRAME ON command. 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 where the last SEND OFF command stopped it.
