Wireless Setting Procedure; Term; Pre-Check; Channel Allocation - Sony STWA-C101 Mode D'emploi

Wireless Setting
Procedure
This chapter describes the wireless setting
procedure. In particular, the decision process
for wireless channel allocation and the
wireless communication trouble shooting
process are described, including:
- Wireless channel allocation with multiple
screens
- Trouble shooting, such as sound and
caption interruption.
As a number of transmitters are allocated for
various screen areas in one theater, one
transmitter may affect another screen's
wireless communication area.
This wireless system uses the 2.4GHz
frequency, and it is possible that other
2.4GHz wireless signal sources, e.g., Wi-Fi
may cause interference in this system.
This chapter describes the wireless channel
allocation procedure, and workarounds for
smooth installation.
This chapter is intended for a theater
operator and Sony service engineer.

Term

Crosstalk: Phenomena resulting in another
transmitter's signal reaching a different
screen area.
Interference: Infringement of signal from
another wireless signal source of the same
frequency.
Channels: 14 channels that user can choose
G1 - G7 and Y1 - Y7.
Channel number: The numeric attached to
the Channel indicates wireless frequency.
For example, G1 and Y1 use the same
frequency.
Channel-pair: Channels that use the same
channel number. For example, G1 and Y1
are channel-pair.

Pre-Check

- Check all 2.4GHz wireless systems in the
theater.
- Stop them if they are not used.
Check regularly to make sure that
unnecessary systems are not working.
The STWA-C101/STW-C140GI system
uses the 2.4 GHz frequency. Other devices
that use the same frequency may cause
interference in this system.

Channel Allocation

Allocate the channel for each screen based
on the following fundamental allocation
rule. Otherwise, wireless communication
may not work as a result of crosstalk or other
interference.
There are 14 channels: G1 to G7 (G group)
and Y1 to Y7 (Y group). G group and Y
group communicate independently, even if
they share the same channel number. For
example, although G1 and Y1 share the
same frequency, these channels can be
separated from each other.
