In addition, the 811 Video / Audio Generator:
 Lets you adjust the amplitude and frequency of the balanced audio signal
 Lets you determine the video output standardPAL or NTSCvia the
VIDEO STANDARD button
 Offers 74 static or moving patterns, all of which are available in each
video standard
 Transmits a video signal to each output simultaneously
The 811 can be rack-mounted using the RK-80 19” rack adapter. 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 and position
your Kramer 811 away from moisture, excessive sunlight and dust

5 Installing on a Rack
This section describes what to do before installing on a rack (see section 5.1)
and how to install on a rack (see section 5.2).
5.1 Before Installing on a Rack
Before installing the machine in a 19" rack, be sure that the environment is
within the recommended range:
Table 4: Recommended Ambient Temperature and Humidity Range
Operating temperature range +5 to +45 Deg. Centigrade
Operating humidity range 5 to 65 % RHL, non-condensing
Storage temperature range -20 to +70 Deg. Centigrade
Storage humidity range 5 to 95% RHL, non-condensing
5.1.1 CAUTION!!
When installing the 811 in a 19" rack, avoid hazards by taking care that:
1. It is located within the recommended environmental conditions, as the
operating ambient temperature of a closed or multi-unit rack assembly
may exceed the room ambient temperature.
2. Once rack-mounted, enough air will still flow around the machine.
3. The machine is placed straight in the correct horizontal position.
4. You do not overload the circuit(s). When connecting the machine to the
supply circuit, overloading the circuits might have a detrimental effect on
overcurrent protection and supply wiring. Refer to the appropriate
nameplate ratings for information. For example, for fuse replacement, see
the value printed on the product label.
5. The machine is earthed (grounded) in a reliable way and is connected only
to an electricity socket with grounding. Pay particular attention to supply
connections other than direct connections to the branch circuit (for
example, the use of power strips), and that you use only the power cord
that is supplied with the machine.
5.2 Instructions for Rack-Mounting
To install the 811 in a 19" rack, place the rack ears of the rack adapter
1
against the rack rails of the rack, and insert the proper rack screws through
each of the four holes in the rack ears.
1 Always mount the machine in the rack before you attach any cables or connect the machine to the power. If you are using a
Kramer rack adapter kit (for a machine that is not 19"), refer to the Rack Adapters user manual (download it at:
http://www.kramerelectronics.com) for installation instructions

6 Connecting the 811 Video / Audio Generator
To use your 811 Video / Audio Generator, connect one or more of the
outputs
1
, as the example in Figure 3 illustrates:
1. Connect the BLACK BURST OUT 1 BNC connector to a black burst
acceptor (for example, a genlockable camera).
2. Connect the CV BNC connector to the composite video acceptor (for
example, a display).
3. Connect the COMP. (component video) Y, U and V BNC connectors to
the component video acceptor (for example, a Betacam recorder).
4. Connect the SDI 1 BNC connector to the SDI acceptor (for example, an
SDI display).
5. Connect the s-Video (Y/C) 4p YC OUT connector to the s-Video (Y/C)
acceptor (for example, an AV Switcher (Diagnostic)).
6. Connect the AUDIO OUT terminal block to the audio acceptor (for
example, an AV Switcher (Diagnostic)), see section 6.1.
7. Connect the power cord (not illustrated in Figure 3).

number.
2. Observe the output on the acceptors (see Table 5 for reference).
3. Adjust the video equipment, as required.
You can only select one video pattern at a time for all the connected outputs
7.2 Adjusting your Audio Equipment
To adjust your audio equipment using the 811, do the following:
1. Press the AUDIO AMPLITUDE + or – buttons, and/or the AUDIO
FREQUENCY + or – buttons to set the desired audio amplitude and
frequency.
2. Adjust your audio equipment, as required.
1 To display the next pattern or the previous pattern, respectively
