3.15. MCDL – Multi-Channel Data
Link
(Waveform Date Acquisition)
The APX RS has connectivity with the Photron MCDL (Multi-Channel Data Link –
optional), which makes it possible for the APX RS to record sampled waveform data (up
to 4 channels of analog and 6 channels of digital signals) along with image date. The
original waveform data from the MCDL is sampled at the frequency of ten times the
current frame rate and the sapling tales place at a timing of every tenth of each frame
period.
The recorded data is played as a waveform on the PFV (Photron FASTCAM Viewer).
Also, it is added to the header when the image data is stored in the TIFF format. It may
also be viewed on video monitor.
The following describes how to operate the APX RS together with an MCDL unit.
1. Connect the MCDL output cable to the MCDL connector (9-pin D-sub) on the APX
RS rear panel.
2. Press the MENU key on the keypad to display the menu list. Move the cursor to
select the [MCDL/IRIG] menu. Further select the [MCDL ON] and press the ENTER
key to set it on.
3. The waveform of the input signal is displayed in the text portion of the screen.
4. The waveform is now recorded superimposed on and in sync with the image.
5. To play a recorded waveform, press the LIVE/MEMORY key to get in the MEMORY
mode. Press the PLAY key and the recorded waveform is shown superimposed on
each corresponding image.
