The Radio Comm Settings change the serial port settings on the ZN-
241G. The dialog box that opens when you first start ZNWizard changes
the settings for your PC but doesn’t change the radio settings. When you
make changes to these settings in the ZN-241G, ZNWizard automatically
changes the settings on your PC so you can still talk to the radio.
Baud
Rate
This is the speed that the ZN-241G talks to other devices
through its serial port. You can divide the baud rate by 10 to
find out how many bytes per second data will be sent to and
from the ZN-241G. The baud rate does not change how fast
the ZN-241G sends data over the air. The ZN-241G
supports the standard PC baud rates from 4800 to 115,200.
Parity Bit
The parity bit is an error-checking bit that can be used to
make sure data is received correctly over the serial port. It
was used frequently in the early days of computers but is
rarely used today.
Stop Bits
Stop bits are used in serial communications to indicate
where one byte stops and another begins. It is typically set
to 1 for most serial communications. The ZN-241G supports
both 1 and 2 stop bits.
Channel
Mask
The ZN-241G has 16 different wireless channels it can use
to communicate. The channels in the ZN-241G are like
channels on a radio or TV station. In order to hear each
other, radios must be “tuned” to the same channel.
Sometimes when other networks of ZN-241Gs are in the
same location, radios on one Network ID might interfere with
radios on another Network ID if they use the same channel.
The Channel Set lets you choose which channel to “tune” to.
The ZN-241G has a special feature that allows it to
automatically select the best channel to set up the network.
You can let the ZN-241G pick from one, two, three, up to all
of the 16 channels when selecting the best channel. When
more than one channel is selected, the ZN-241G will listen
on the first channel selected. If it hears another radio that is
too “loud” it will try another channel until it finds a channel
that is “quiet.” The ZN-241G will use this “quiet channel” to
set up the network.
