4.14. IRIG Time Code
The APX-i2 is compatible with the IRIG-B signal input and can add an IRIG code to
each recorded frame. The sampling of IRIG code is once every frame.
The IRIG code recorded on each frame is displayed on video screen or PFV screen. It
is added to the header when the recorded image data is stored in the TIFF format.
The required specification of IRIG code is as follows:
Connector: BNC
Code Format: IRIG
－ B (122), Analog
Amplitude: 1.2 Vp-p Minimum; 8.0 Vp-p Maximum
Modulation Ratio: 2:1 to 4:1
The following describes how to use the MCDL:
1. Connect the IRIG generator output cable to the IRIG IN connector (BNC) on the
APX-i2 rear panel.
2. Press the MENU button on the keypad to display the menu list. Move the joystick
to select the [MCDL/IRIG] menu. Further select the [IRIG ON] and press the
joystick down to set it on.
3. IRIG code is displayed in the text portion of the screen.
4. The IRIG code is now recorded on the image.
5. To play a recorded IRIG code, press the LIVE/MEMORY button to get in the
MEMORY mode. Press the PLAY button and the recorded IRIG code is shown
superimposed on each corresponding image.
Note: This feature cannot be used at 128 x 16 resolution.
Note: When you use both MCDL and IRIG, select [MCDL IRIG ON].
Adding offset to sampled IRIG time code
To add an offset to sampled IRIG time code, follow the below procedure:
1. Go to the IRIG OFFSET menu
2. Specify a value for offset b0.999999 and -0.999999 sec.
3. An offset is added to each of the sampled IRIG codes.
