• s-video (Y/C)
• RGsB or YUV1
In addition, the FC-7402:
• Includes full ProcAmp control of the video via the front panel and
7-segment display, and via RS-232, with the option to store the settings in
non-volatile memory
• Has an internal 75% color bar generator, whose timing is based on the
SDI input
• Encodes 525 line signals to NTSC3.58 or NTSC4.43, and 625 lines to
PAL-B, D, G, H, I or Combination PAL-N. When encoding NTSC, it can be
programmed with or without a 7.5 IRE setup (pedestal)
• Can be controlled via a user-friendly Windows® based program that can
modify parameters such as hue, contrast, brightness, sharpness, and color
• Lets you store/recall up to 10 setups in non-volatile memory
To achieve the best performance:
• Connect only good quality connection cables, thus avoiding interference,
deterioration in signal quality due to poor matching, and elevated noise levels
(often associated with low quality cables)
• Avoid interference from neighboring electrical appliances that may
adversely influence signal quality
• Position your Kramer FC-7402 in a location free from moisture and away
from excessive sunlight and dust

5.1 Connecting the FC-7402 SDI to Analog Converter
To connect1the FC-7402, do the following:
1. Connect the SDI source (for example, a digital camera) to the SDI IN
BNC connector. You can also connect (OPTIONAL) the SDI OUT BNC
connector to an SDI acceptor (for example, an SDI monitor).
2. Connect the CV OUTPUT BNC connector to a composite video acceptor
(for example, a composite video monitor).
3. Connect the Y/C OUTPUT 4p connector to an s-Video acceptor (for
example, an s-Video monitor).
4. Connect the component video OUTPUT BNC connectors, Y / G, B-Y / B,
and R-Y / R to either a YUV or an RGB video acceptor, as follows:
• A BETACAM VCR (YUV) to Y/ G, B-Y / B, and R-Y / R (DIP 1 OFF), or
• A plasma monitor (RGB) to Y/ G, B-Y / B, and R-Y / R (DIP 1 ON)
5. Connect a PC or other controller, if required (see section 5.1.1).
6. Set the dipswitches (see section 5.1.2).
7. Connect the AC power cord.

5.1.1 Connecting a PC
To connect a PC to the FC-7402 unit, using the Null-modem adapter
provided with the machine (recommended):
• Connect the RS-232 DB9 rear panel port on the FC-7402 unit to the
Null-modem adapter and connect the Null-modem adapter with a 9 wire flat
cable to the RS-232 DB9 port on your PC
To connect a PC to the FC-7402 unit, without using a Null-modem adapter:
• Connect the RS-232 DB9 port on your PC to the RS-232 DB9 rear panel
port on the FC-7402 unit, as Figure 3 illustrates(depending on whether the PC
has a 9-pin or 25-pin connector)

5.1.2 Dipswitch Settings
Configure the FC-7402 unit by setting the 8 dipswitches, as Table 3 defines:
Table 3: Dipswitch Definitions
Dipswitch Set as follows:
1 RGB ON for RGB, OFF for YUV
2 VBI1ON to enable Vertical Interval Blanking; OFF to disable
3 PEDESTAL2ON for pedestal (7.5 IRE offset selection for NTSC); OFF for no pedestal
4 4XOVRSMPL ON to enable oversampling3; OFF to disable oversampling
For 2 X OVRSMPL (see section 5.1.3)
5 NTSC ON for NTSC 3.58 (see Table4)
6 PAL ON for PAL-B (see Table4)
7 AUTO ON for multi-standard; OFF for user-selected (fixed) standard (see Table4)
8 BAR ON for machine to operate as a 75% color bar generator (based on the clock of
the SDI input)
Table 4: Dipswitch Settings (AUTO, PAL, and NTSC)
AUTO PAL NTSC FC-7402 Output Standard
OFF OFF OFF NTSC 4.43
OFF OFF ON NTSC 3.58
OFF ON OFF PAL-B
OFF ON ON PAL-N
ON OFF OFF PAL-N for 625 line SDI input; NTSC 4.43 for 525 line SDI input
ON OFF ON PAL-N for 625 line SDI input; NTSC 3.58 for 525 line SDI input
ON ON OFF PAL-B for 625 line SDI input; NTSC 4.43 for 525 line SDI input
ON ON ON PAL-B for 625 line SDI input; NTSC 3.58 for 525 line SDI input
1 For example, passing data such as Teletext
2 NTSC offsets the black level within the active video signal by 7.5 IRE when selected
3 When a signal is digitally sampled at frequencies much higher than the NYQUIST frequency. When this method is used, the
noise figure is improved

5.1.3 Adjusting Oversampling to x2 (Moving Jumper JMP1)
Setting DIP 4 ON enables oversampling1, which provides the picture with a
better S/N ratio. The default is x4 (recommended). However, you can adjust
this factory preset to 2 X OVRSMPL.
To adjust oversampling to x2, do the following:
1. Set DIP 4 OFF and remove the power cord.
2. Open the FC-7402 unit and move Jumper JMP1 to the left (see Figure 4).
3. Close the FC-7402 unit, set DIP 4 ON and connect the power cord to the
mains electricity.

5.2 Operating the FC-7402 SDI to Analog Converter
Operate your FC-7402 via:
• The front panel buttons
• RS-232 serial commands transmitted by a touch screen system, PC, or
other serial controller
To operate the FC-7402 using the front panel buttons, do the following:
1. Turn on the power.
The signal from the SDI source is automatically converted to composite video,
s-Video, and component video (YUV if DIP 1 is set to OFF, or RGB if DIP 1
is set to ON).
2. If necessary, adjust the brightness, contrast, hue, sharpness, and/or color
of the picture, as follows:
• Press the appropriate button1
The button illuminates and the 7-segment display shows the current level (in digits)
• Press and release the + button or - button once to gradually increase or
decrease the current level by one unit
The 7-segment display shows the new level
Note: To increase or decrease the current level rapidly, press and hold down
the + button or - button, continuously2. To end the rapid adjustment, release
the + button or – button.
5.2.1 Storing/Recalling Setups
You can store and recall up to 10 setups (or adjustments) in non-volatile
memory, using the STO and RCL buttons together with the + and – buttons.
To store3a setup, do the following:
• Press the STO button and then select a setup # between 1 and 10 by
pressing the + and – buttons
• Press the STO button again
The current settings are saved to that setup #
To recall a setup, do the following:
• Press the RCL button and then select the appropriate # (that corresponds
to the setup #) by pressing the + and – buttons
• Press the RCL button again
The selected setup is recalled
1 See items 2 to 6 in Table 1
2 The 7-segment display starts to quickly scan the range. When it stops running, it has reached the maximum or minimum,
respectively
3 Storing a new setup over a previous setup # replaces the previous setup #
