2.8 DISABLING THE TIMED SEQUENCE MODE
To avoid accidentally enabling the timed sequence mode, turn switch 4 ON.
This will disable the timed mode.
2.9 DISABLING BREAKAWAY AUDIO
To disable the breakaway audio feature, turn switch 5 ON.
2.10 VERTICAL INTERVAL SWITCHING
All units are now fitted with the vertical switching option. Switching will
occur during the vertical interval, referencing the sync signal on input number
one. If input number one has no input, switching will be random with respect to
sync. Note: vertical interval switching has no meaning unless the inputs are
synchronous to one another.
SECTION 3. OPERATION
3.1 INTRODUCTION
This section explains in detail the operation of the RS4x4HB using either the
front panel push-button switches or the RS232 port.
3.2 CONNECTIONS
Connect audio and video sources as described in sections 2.4 and 2.5. There
is no requirement that all inputs be used.
If outputs are left over they may be used like a distribution amplifier to buffer
and distribute an input signal. To use extra outputs in this way simply route the
input you wish to distribute to as many available outputs as desired.
Outputs may be looped back to unused inputs via short cables for the purpose
of adding delays, but be aware that if an output is then routed to that same input,
an illegal condition will exist and the output will oscillate at frequencies which
could spill over onto other crosspoints.
3.3 ROUTING VIA THE FRONT PANEL SWITCHES
3.3.1 HOW TO ROUTE AUDIO AND VIDEO TOGETHER
Select the destination (output) you wish to route a signal to and push (and
release) the front panel button with the number; the row of LEDs to the right of the
button you pushed will flash. Then select the source (input) audio and video you
wish to have routed to that output and push the front panel button with that input
number. The row of LEDs will stop flashing and the lamp corresponding to that
crosspoint will then glow steadily.
If you do not push an input button within ten seconds, the LEDs will stop
flashing and the crosspoint will remain where it was.
3.3.2 HOW TO ROUTE AUDIO SEPARATELY
Select the destination (output) you wish to route an audio signal only to and
push the front panel button with that number twice (two quick pushes). The row of
LEDs to the right of the button you pushed will flash, as when you route both
signals together. Then select the source (input) audio you wish to have routed to
that output and push the front panel button with that input number. The row of
LEDs will stop flashing and the lamp corresponding to the audio crosspoint will
flash slowly, while the LED corresponding to the video crosspoint will glow steadily.
If you do not push an input button within ten seconds, the LEDs will stop
flashing and the crosspoint will remain where it was.
