Overview

3 Overview
The high quality FC-7501 is a multi-standard converter that converts
professional quality video to serial digital video (SDI).
The following analog formats are supported:
Composite video
s-Video
Component video (Y, B-Y, R-Y, sometimes called YUV or Y, Pb,
Pr)
The FC-7501 maintains the high level of professional video quality,
prevalent with component video output devices and DVD players, when
converting to SDI.
The FC-7501 automatically detects the input standard, generating the
appropriate output:
For component video input, 50Hz/625 line (interlaced) and
60Hz/525 line (interlaced) are supported
For YC and CV inputs, all variations of PAL, NTSC and SECAM
are supported
In addition, the FC-7501features:
SDI conversion on 2 buffered and reclocked SDI outputs
Input looping connectors and a 75/Hi-Z input termination switch
An RS-232 port
Control via a user-friendly Windows®-based program that can
modify video parameters such as contrast, saturation and hue,
which may be stored in non-volatile memory
True 10-bit digitizing - ideal for broadcast applications
To achieve the best performance:
Use only good quality connection cables
1
to avoid 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
FC-7501 in a location free from moisture and away from
excessive sunlight and dust

5 Using Your Analog Video to SDI Converter
You can use your FC-7501, to convert professional quality composite
video, s-Video or component video (as the example in Figure 2 illustrates)
to one or two SDI video outputs.
To convert component video to two SDI video outputs, do the following:
1. Connect a component video source (for example, a Betacam component
VCR) to the component video BNC input connectors, Y, B-Y, and R-Y.
2. Connect both SDI outputs to SDI acceptors as follows (when only one SDI
output is required, use either of the SDI outputs of the FC-7501, and leave
the other SDI output unconnected):
Connect the SDI OUT 1 BNC connector to an SDI acceptor
(for example, a Non-Linear Editor)
Connect the SDI OUT 2 BNC connector to the second SDI
acceptor (for example, an SDI monitor)
3. Connect the component video loop connectors, LOOP Y, LOOP B-Y,
and LOOP R-Y, to a component monitor, and release the Hi-Z/75
button to Hi-Z (optional).
When the inputs are not looped, the Hi-Z/75button should be pressed
4. Connect the 12V DC power adapter to the power socket and connect the
adapter to the mains electricity.
1 For s-Video, connect the CV/Y and the C/R-Y connectors
2 For component video, connect all 3 connectors: Y, B-Y, and R-Y
3 Push in to terminate the input. Release when the input extends to another unit

5. Turn on the power and press the COMP. (Component video) button.
The component video signal converts to SDI at both SDI OUT 1 and SDI
OUT 2.

6 Upgrading the FC-7501 to an FC-7501P
You can improve the SDI Pixel Jitter by converting the FC-7501 to an
FC-7501P (an Analog Video to SDI Converter with very low jitter), as
explained in the following steps.
6.1 Inserting the 7501M Module
1. Unfasten the two pairs of screws on each side of the cover of the FC-7501
and remove the cover, as Figure 3 illustrates:
Figure 3: Removing the Cover of the FC-7501
2. Remove jumpers on J7 and J8 (see Figure 4.)
3. Insert the optional 7501M module (“PLL board”) onto the two sets of 16
pins, and secure it to the spacer by fastening the washer and screw
1
, as
shown in Figure 4.

4. Replace the cover on the FC-7501, and secure it in place by fastening the
two pairs of screws on each side of the cover.
The FC-7501P is an upgraded FC-7501 unit (with the 7501M added).

8 Communications Protocol for the FC-7501
2
RS-232 communication with the FC-7501 complies with the following
protocol. The protocol uses 4 bytes of information, and data is at 9600 baud,
with no parity, 8 data bits and 1 stop bit. A null-modem RS-232 connection
should be used between the PC (or other controller) and the FC-7501. That
is, for a DB-9 port, connect as follows:
Connect pin 5 of the PC to pin 5 of the machine
Cross pins 2 and 3, ie. connect pin 2 of the PC to pin 3 of the
machine, and connect pin 3 of the PC to pin 2 of the machine
On the PC side, short pins 4 and 6
On the PC side, short pins 1, 7 and 8.
