Installing the VS-42HC on a Rack
5 Installing the VS-42HC on a Rack
This section describes what to do before installing on a rack and how to rack mount.
Before Installing on a Rack
Before installing on a rack, be sure that the environment is within the recommended 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
CAUTION!!
When installing on 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.
How to Rack Mount
To rack-mount the machine: 1 Attach both ear brackets to the
machine. To do so, remove the screws from each side of the machine (3 on each side), and replace those screws through the ear brackets.
2 Place the ears of the machine
against the rack rails, and insert the proper screws (not provided) through each of the
four holes in the rack ears. Note that: In some models, the front panel
may feature built-in rack ears Detachable rack ears can be
removed for desktop use 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"), see the Rack Adapters user manual for installation instructions (you can download it at: http://www.kramerelectronics.com)

Operating the VS-42HC
8 Operating the VS-42HC
You can operate your VS-42HC via:
 The front panel buttons  RS-232/RS-485 serial commands transmitted by a touch screen system,
PC, or other serial controller
 Infra-red remote control transmitter This section describes:
 How to use the front panel buttons  How to set and adjust the audio delay time
8.1 Switching OUT-IN Combinations
There are two sets of INPUT SELECTOR buttons, the first set, TO OUTPUT 1, for switching an input (from 1 to 4) to OUT 1 and the second set, TO OUTPUT 2, for switching an input (from 1 to 2) to OUT 2.
To switch a video/audio input to a video/audio output, press any of the INPUT SELECTOR buttons (from 1 to 4) TO OUTPUT 1 or TO OUTPUT 2, as required.
For example, press INPUT SELECTOR button 4 TO OUTPUT 1 and INPUT SELECTOR button 1 TO OUTPUT 2. Now IN 4 is switched to OUT 1 and IN 1 is switched to OUT 2. The corresponding buttons illuminate.
To turn off an output channel, press that channel’s illuminated button once more.
8.2 Setting and Adjusting the Audio Delay Time
You can adjust the audio delay time for OUT 2 to correct lip sync errors so that the audio delay will match the video delay. The delay time can be set and stored separately for each input channel.
To set or adjust the audio delay, do the following:
1. Press the DELAY button on the front panel. The DELAY button blinks
2. Press the + and – buttons to increase or decrease the delay time1 respectively. The + and – buttons illuminate.
1 Press and hold the + or - buttons for speedy increase or decrease of the audio delay time respectively
