Lasershow Timecode TC2000
Some installations require coordination with music and control signals.
This is most often done using SMPTE timecode. The timecode will be recorded
on one audio track. Then, at playback time, the timecode audio is read and
decoded by a SMPTE timecode reader device.
Using SMPTE with
LD2000
Pangolin systems cannot read
SMPTE directly. This is because QM boards used with LD2000 do not
have SMPTE reading circuits. Instead, you
need SMPTE readers
designed to connect to computers. These are common in the audio-visual and
electronic music field. The SMPTE reader will connect to the computer's via
a port (parallel, serial, USB) or internal card.
Lasershow Timecode TC2000
controller
Pangolin's
Lasershow Timecode TC2000 controller reads and writes SMPTE timecode,
when used in conjunction with a Lasershow Designer 2000 host
computer.
- In reading mode, the TC2000 decodes
incoming SMPTE timecode and passes it to Lasershow Designer 2000.
Playback of your laser show is then locked to the incoming SMPTE
timecode. If timecode stops, the laser show stops (alternatively,
you can set the show to continue "freewheeling"). If timecode
backs up and starts again, the laser show also backs up and starts
again.
- In writing mode, the TC2000 outputs a SMPTE-encoded
audio signal. Typically, you would then record this on a tape deck
or other recording device.
The TC2000 is very compact -- smaller than a
paperback book. It measures just 4.38" x 3.25" x 1.25" (11 x 8.25 x
3.18 cm).
How the TC2000
works
 There are four connectors on the TC2000:
- The OUT jack on the front is for writing a SMPTE-encoded audio signal to a tape deck or other external
recording device.
- The IN jack on the front is for reading a SMPTE-encoded audio signal that is coming from another device.
-
The
Power Input jack on the back takes a 9-12 volt AC or DC power.
This is provided by an included "wall wart" transformer.
- The Serial Port on the back is used to
communicate with your Lasershow Designer 2000 host computer. The
port is a female 9-pin RS-232 serial connector. Use an appropriate
adapter cable to plug into the USB or serial port on your
computer.
Software to control the TC2000 is built right
into Pangolin's Lasershow Designer 2000 system. In the LD2000
program "Showtime", you can set playback to be controlled by SMPTE.
You'll see the incoming SMPTE timecode, and the laser show will
follow the timecode exactly.
