3 Overview
The Kramer DigiTOOLS 7408 SDI to Analog Converter is a high quality, full
10-bit SDI to Analog video converter in a Kramer Tool housing. The 7408
SDI to Analog Converter is a multi-standard unit, converting 525-line SDI to
NTSC or NTSC4.43, and 625-line SDI to PAL-B/D/G/H/I/N. Despite its
small size, the converter has many features, including:
 Reclocked and equalized SDI output (loop)
 4 times digital over sampling to minimize digital artifacts

 Output configuration to Composite Video and s-Video (Y/C), or
component video (YUV)
 User-friendly Windows PC software, provided for ProcAmp control via
RS-232 for adjusting parameters such as contrast, hue, saturation and
sharpness
 NTSC encoding with or without a 7.5IRE setup
 Perforated cover to prevent chip overheating
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 and position your Kramer 7408 away
from moisture, excessive sunlight and dust

5 Using Your 7408 SDI to Analog Converter
You can use your 7408 SDI to Analog Converter to convert SDI video to
professional analog video: composite video and s-Video, or component video
(as the example in Figure 2 illustrates).
5.1 Connecting Your 7408 SDI to Analog Converter
To connect the 7408, do the following
1
:
1. Connect the SDI source (for example, a digital camera) to the SDI IN
BNC connector. You may also connect the SDI OUT BNC connector to
an SDI acceptor (such as an SDI monitor).
2. Connect the following:
 An s-video acceptor (such as an s-video monitor) to the CY output
BNC connectors; and/or,
 A composite video acceptor, such as a composite video monitor to
the CV output BNC connector; or,
 A component video acceptor, such as a BETACAM VCR, to the
YUV BNC connectors
3. Connect a PC (if required) to the RS-232 port (see section 5.2).
4. Set the dipswitches, as section 5.3 describes.
5. Connect the 12V DC power adapter to the power socket and connect the
adapter to the mains electricity.
1 Switch OFF the power on each device before connecting it to your 7408. After connecting your 7408, switch on its power
and then switch on the power on each device

5.2 Connecting a PC
To connect a PC to the 7408 unit, using the Null-modem adapter provided
with the machine (recommended):
 Connect the RS-232 DB9 rear panel port on the 7408 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 7408 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 7408 unit, as Figure 3 illustrates (depending on whether the
PC has a 9-pin or 25-pin connector)

5.3 Setting the Dipswitches
Configure the 7408 unit by setting the dipswitches, as Table 2 defines:
Table 2: Setting the Dipswitches
DIPS Function Description
1 PROGRAM ON for upgrading firmware; otherwise OFF
2 VBI ON to enable Vertical Interval Blanking; OFF to disable
3 PEDESTAL

ON for pedestal (7.5 IRE offset selection for NTSC); OFF for no pedestal
4 4XOS
2
ON to enable oversampling
3
; OFF to disable oversampling
5 NTSC ON for NTSC 3.58 (see Table 3)
6 PAL ON for PAL (see Table 3)
7 AUTO ON for multistandard; OFF for user selected (fixed) standard (see Table 3)
8 COMPONENT ON for component video; OFF for composite video and/or s-video

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 NTSC offsets the black level within the active video signal by 7.5 IRE when selected
2 4xOS is 4 x Oversample
3 When this method is used, the noise figure is improved
