Advanced Features
Overview:
The
Update Channel / Power Utility
software and its usage instructions are on the CD included in the ZeroWire
shipping box. The utility allows the user to configure some of ZeroWire transmitter and receiver parameters. The
parameter settings are discussed in the following paragraphs. Note: These settings can only be changed using a
computer to connect to a ZeroWire unit and running the
Update Channel / Power Utility
software.
Deep Sleep Selection (Tx only):
When
Deep Sleep
set to ON the ZeroWire Tx goes into
Deep Sleep
after 3 minutes if no video input is detected, or
if its corresponding Rx unit is powered off, or disconnected from the receiving display.
Restoring video will “wake up” the Tx.
When
Deep Sleep
is set to OFF, the wireless link will automatically be re-established, as soon as the Tx detects a
Rx. NDS recommends: Setting
Deep Sleep
to ON when using more than three systems in the same area, and
setting
Deep Sleep
to OFF when using three or fewer systems.
Note: When the TX unit is in the
Deep Sleep
state, its LED’s cadence will be: blinking yellow for 1 second, then off
for 3 seconds. To wake the Tx unit, press its bonding button and the TX’s LED switches to blinking amber. Also,
restoring video will bring the Tx out of the sleep state.
Channel Selection (Tx only):
This feature allows the user to “lock” a Tx to one of the 3 available channels or allow
3 Channel
selection.
3
Channel
is the default.
3 Channel
recommendations are on the following page.
ATPC Selection (Tx & Rx):
When
ATPC
set to OFF
,
the system will operate at maximum transmit power, making the wireless link more robust
when obstructions to the line-of-sight are introduced. When
ATPC
is set
to
ON
,
the system transmits at a lower
power level determined by the relative distance between the Tx and Rx units. The advantage of having
ATPC
ON
is
that it allows more ZeroWire systems to operate in the same area by minimizing the transmit power and
decreasing the potential for co-channel interference. NDS recommends that
ATPC
be set to
ON
when using more
than three systems in the same area and set to OFF when using three systems or less.
Recommended Settings:
One ZeroWire Pair:
In this case, either the
3 Channel
or “fixed channel” setting may be used.
Two or Three ZeroWire Pairs:
Setting each pair to a specific RF channel eliminates the potential for co-channel interference, as each system operates on its own
dedicated channel.
Four or more ZeroWire Pairs:
Select the
3 Channel
setting so each pair automatically selects an available channel upon power up. This minimizes the chance of
co-channel interference occurring.
