Knox Video RSIII - Manual (Page 15)

SECTION 3. OPERATION
3.1 INTRODUCTION
This section explains the operation of the RSIII using the Front Panel push-button switches, the
RS232/RS422 serial ports, or the Ethernet port.
On power up, the front panel display will indicate our company’s name for a few seconds then
display the current configuration. The configuration consists of the Switcher Series, which is
RSIII; the Model type RGBHV, RGB, SVID, COMP or AO; the number of video inputs and
outputs; the type of video connector; the type of audio UBAS, BAS, MIXED or VO; whether
there is an optional Volume Tone board installed; the number of audio inputs and outputs; if there
is an optional D-CAT board installed and finally if the unit has Ethernet communications ability.
After a while, the display will revert to its normal status screen. At this point, the operator can
use any of the three methods of controlling the unit.
3.2 CONNECTIONS
Connect audio and video sources and destinations as described in section 2. There is no
requirement that all inputs or outputs be used or terminated, but be sure that all outputs that are
used are properly terminated.
Outputs should not be looped back to unused inputs.
3.3 CONTROL VIA THE FRONT PANEL
The Front Panel displays information about the condition of the RSIII crosspoints and the settings
of the optional volume and tone, VT, for each output. The display consists of a Vacuum
Florescent Display with a rotary switch to select the output number and to adjust VT parameters.
In addition, an array of up to 32 push-button switches allows for the selection of crosspoints and
storage/recall of stored crosspoint patterns.
3.3.1 DISPLAYING THE CROSSPOINT CONNECTIONS AND VTB VALUES
In idle mode, line 1 of the display shows an output number (always output 1 at power up), the
Video input number connected to that output, and the Audio input number connected to that
output. Line 2 shows the current VT settings for that output number: Volume, Bass, Treble, and
Balance. To stop the crawling motion push the Clear button or turn the rotary switch (the display
will resume crawling after a few seconds). A typical display might look like:
OUT:01 VIDEO:03 AUDIO:03
V: -07 B: +2 T: -1 BAL: 0
To view the crosspoint and VT data for another output, turn the rotary until the desired output
number shows on line 1 of the display.
3.3.2 CHANGING A CROSSPOINT CONNECTION
Changes may be made to the video crosspoint, the audio crosspoint, or both. Two indicators
under the display show whether Video, Audio, or Both will be affected. Before starting a
crosspoint change, push the Select button one or more times until the correct combination of
lights is shown. You can make crosspoint changes with the 16 input buttons and 16 output
buttons on the right. Start by pressing either an input number or with an output number, and then
push the other connection you want to make.
When making a crosspoint change, pushing one of
the 16 input or output buttons will cause the Armed LED to light indicating a change is pending.
Make the desired output or input connection, or push Clear to start over. If no crosspoint selection
is made, the armed light will go off after five seconds the user will have to start all over again.
