Kramer Electronics VP-31 - Manual (Page 11)

INSTALLATION
Rack Mounting
The VP-61RS switcher included in this manual may be rackmounted in a standard 19” (1U) EIA rack
assembly, and includes rack “ears” at the ends of the front. The VP-31 and the VP-32xl can be installed in a
rack, using a special rack adapter (contact your KRAMER dealer). These machines do not require any specific
spacing above or below the unit for ventilation. To mount any of the switchers, simply place the rack ears
against the rails of your rack, and insert standard screws through each of the four corner holes in the rack ears.
CONNECTING TO VGA/XGA DEVICES
Video sources and output devices (such as monitors, projectors or recorders) may be connected to the
switchers through the HD 15F connectors located on the back of the unit. Unused inputs are terminated to
75ohm, and active inputs should be terminated by the connecting source. Please keep in mind that the output
signal format will match that of the input signal format. (Example: If VGA is input, then VGA is output).
CONNECTING TO AUDIO DEVICES
Audio sources and output devices may be connected to the switchers (VP-32xl only) through the RCA type
connectors located on the back of the unit.
USING THE SWITCHERS
Powering on the Switcher
NOTES
Switcher should only be powered on, after all connections are
completed, and all source devices have been powered on. Do
not attempt to connect or disconnect any video, audio or
control signals to the switcher while it is powered on!
The socket-outlet should be near the equipment and should be
easily accessible. To fully disconnect equipment, remove power
cord from its socket after it has been turned off.
1) Press the toggle switch on the far-left front panel to the up position. In the up position, the toggle switch
glows and the active input button illuminates, as well.
2) Operate the acceptors.
Selecting an Input on the Switchers
Input selection on the switchers described in this manual is simply made by pressing buttons marked “ 1”, “2”
etc. (or " A", "B", "C" etc.) on the front panel, or by operating via your preferred remote device (see section
9.3). These buttons correspond to the input connections as marked on the back panel.
Controlling the VP-32xl
The VP-32xl switcher can be controlled by the following methods:
1) By touch buttons on the front panel (see section 9.2 "Selecting an Input on the Switchers").
2) By direct remote contact closure via the terminal block connector (e.g. a switch panel that the customer
rigs up).
To remote control the VP-32xl, wire the Remote connector as shown in Figure 4. Grounding one of the inputs
1-3 selects the active input to be switched to both outputs "1" & "2".
