Your FC-20 SDI / DV Transcoder

In addition, the FC-20:

 Auto-detects and supports PAL and NTSC

 Includes AES/EBU Embedded Audio Support (at 48kHz, synchronous to

video)

 Can be powered from a computer using the same 6-pin FireWire cable

that carries the DV stream in and out of the NLE (Non-Linear-Editor)

 Supports the DVITC

time code in the SDI data stream

 Features a separate VITC

input and output for analog decks via two BNC

connectors

 Supports linear time code via the RS-422 port

 Is controllable via an NLE or manually via the DV ENCODE/DECODE

front panel button

 Controls tape decks and other video devices

via the RS-422 port

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-20 in a location free from moisture and away

from excessive sunlight and dust

Connecting the FC-20 SDI / DV Transcoder

5 Connecting the FC-20 SDI / DV Transcoder

To connect the FC-20, do the following:

 Connect the SDI/DV inputs and outputs as required

(see section 6.2)

 Connect a Sony RS-422 controlled deck, if required

 Connect the power source (see section 5.1)

 Set the MODE SELECT dipswitches (see section 5.2)

5.1 Powering the FC-20

The FC-20 features three power options for your convenience:

 An XLR 12V battery pack input

 A Universal DC Power Adapter

 Bus power (via 6-pin FireWire input port)

Power sources are wired in parallel, therefore power is available from any

source at any time. For example, when more than one power source is

connected to the FC-20 unit, the source with the highest voltage takes over

5.2 MODE SELECT Dipswitch Settings

Use the 4-pin dipswitches on the front panel to select the desired operation

mode of the FC-20.

5.2.1 Setting the Audio Group

Dipswitches 1 and 2 are designated for audio group selection: A group of four

audio signals are embedded in the serial digital video bitstream. You may

select the audio group according to the settings in Table 3.

Table 3: FC-20 Audio Group Dipswitch Settings

1 ON ON

2 OFF ON

3 ON OFF

4 OFF OFF

1 Switch OFF the power on each device before connecting it to your FC-20

If you have a laptop connected to your FC-20 and the XLR battery connected too, if the battery voltage dips, the laptop will

take over and vice versa

Connecting the FC-20 SDI / DV Transcoder

5.2.2 Setting DV Audio Channels

Each group usually consists of four audio channels (or two stereo pairs).

To select the desired pair:

 Set dipswitch # 3 to ON for: 1=Left/2=Right; or

 Set dipswitch # 3 to OFF for: 3=Left/4=Right

5.2.3 Setting the VITC or the DVITC Signals

The FC-20 supports DVITC embedded timecode and separate analog VITC

signals.

Dipswitch # 4 determines the source of the DVITC

or VITC timecode:

 Set dipswitch # 4 to ON for Analog VITC

 Set dipswitch # 4 to OFF for DVITC (SDI)

Digital VITC embedded timecode

Operating Your FC-20 SDI / DV Transcoder

6 Operating Your FC-20 SDI / DV Transcoder

Operate your FC-20 via the NLE or the DV ENCODE/DECODE button after

setting the MODE SELECT dipswitches (see section 5.2).

6.1 Understanding the FC-20 LEDs

The FC-20 consists of three LEDs described in the following sections.

6.1.1 The POWER ON LED

The POWER ON LED illuminates after the machine has been turned on and

is ready for operation.

6.1.2 The SDI IN LED

The SDI IN LED illuminates when:

 SDI framing is received in the DV Encode mode

 DV framing is received in the DV Decode mode

6.1.3 The DV DECODE LED

The DV DECODE LED illuminates when the machine operates in the DV

Decode mode.

6.2 Understanding the DV DECODE / ENCODE MODES

You can use the FC-20 to convert DV to SDI signals or SDI to DV signals.

You can operate the FC-20 in one of two modes:

 The DV DECODE Mode:

The FC-20 unit converts DV signals to SDI signals (see section 6.2.1)

 The DV ENCODE Mode:

The FC-20 unit converts SDI signals to DV signals (see section 6.2.2)

Note that in both modes where an NLE is present, switching occurs automatically,

that is, via FCP commands, and so on.

If the camera connects directly to the deck, switching is manual (also, there is no

deck control when using camera <-> deck connectivity).
