3. Connect the BTR-240 to all the wired TR-240s via Ethernet
cables.
•
Use category 5e or better Ethernet cables that are wired
to standards T-568A or T-568B (most Ethernet cables
are built to these standards).
•
Do not use more than 100m (328ft) of Ethernet cable
between devices.
4. Turn on the base station.
•
The menu buttons and LCD backlight illuminate and a
progress bar displays the status while the unit is booting.
•
After approximately 25 seconds, the base station will
have completed the boot cycle and the Status Screen will
be displayed.
•
Activate the connected audio interfaces by navigating
the menu on the LCD screen.
5. Perform a ClearScan.
•
After the base station has completely booted, press and
hold the <MENU> + <SET> buttons for approximately 3
seconds.
•
The base station will run the CleaerScan operation and
select the optimal RF channel for operation.
6. Plug headsets into the TR-240 beltpacks and turn them on,
one by one.
•
For a wireless beltpack that has not been previously set to
wireless mode, press and hold the <TALK> button while
the beltpack boots.
•
For a wired beltpack that has not been previously set to
wired mode, press and hold the <2> button while the
beltpack boots.
•
Allow a few seconds between each beltpack power on.
•
After approximately 20 seconds, a voice prompt will
announce “wireless” or “wired” in the beltpack
headphones indicating that communication has started.
•
The base station will increment the association status on
the Status Screen next to “Assoc: XX” for each of the
active full-duplex beltpacks.
Mixed-Mode Capacity Limit
Up to 8 full-duplex wireless beltpacks can be used with a single
BTR-240 base station for reliable and uninterrupted
communications on a clear RF channel. Many more half-duplex
beltpacks can be used.
While using 8 full-duplex wireless beltpacks, an additional 2
wired beltpacks can be used with the base station and maintain a
reliable communication link.
If a BTR-240 base station is loaded beyond it’s capacity limit, the
usability becomes highly subjective. The users will begin to
experience drop outs and potentially delays in the audio.
Any combination of wired and wireless beltpacks is supported as
long as there are no more than 8 wireless full-duplex beltpacks,
and no more than 10 beltpacks overall.
NOTE: The capacity limit may not be achieved if there is
interference on the RF channel of operation or the
network. For further details, refer to Wireless
Interference and Network Interference in Section 10.
Master Wireless Mode
A master wireless mode configuration consists of only TR-240
beltpacks. Only one of the beltpacks is configured as the master
and provides the coverage area for other beltpacks in wireless
mode. This type of configuration is shown in Figure 7-4.
