Wireless Timing Network WTN-DB
-9-
3.5 Radio Connection
The quality of the network connection for a WTN system is crucial. Before you start to
use the WTN-DB check the connection quality. The LED of the WTN-DB blinks green if
there is a good connection to other WTN devices. It blinks orange if the connection is
poor. There is no communication to other WTN-devices, when the LED of WTN-DB is
continuous on red.
In case you have problems with receiving the data you can try to move the WTN-DB
receiver to get a better reception or to move to another radio channel.
3.6 Adjusting the Baud Rate
It is not possible to adjust the baud rate directly in the WTN-DB. You can adjust it from
another device that is operating in the same team (e.g. WTN). If you adjust e.g. the
baud rate to 9600 baud for the display board in the WTN, it will also change the baud
rate of all other WTN-devices in this team to 9600 baud.
Adjustable Baud Rates:
2400, 4800, 9600, 19200
Factory Setting:
2400 baud
3.7 Adjusting the Power Output
It is not possible to adjust the power output directly in the WTN-DB. You can adjust it
from another device that is operating in the same team (e.g. WTN). If you adjust e.g.
100 mW in the WTN, it will also change power output of all other WTN-devices in this
team to 100 W.
Factory Setting:
10 mW
3.8 Test Mode
If you connect the WTN-DB when the switch is on position 0 (zero) the test mode is ac-
tivated. The test mode will be automatically deactivated if you do not operate the rota-
tion switch for 30 seconds.
In the test mode data is shown on the display board and on a WTN that is on team 1S
in the info-menu. If you rotate the switch you should have the following information on
the display:
0 ........ it shows the MAC number of the WTN-DB
1 ........ it shows the software version of the WTN-DB
2 ........ it shows 2 for switch position 2
3 ........ it shows 3 for switch position 3
4 ........ it shows 4 for switch position 4
5 ........ it shows 5 for switch position 5
6 ........ it shows 6 for switch position 6
7 ........ it shows 7 for switch position 7
8 ........ it shows 8 for switch position 8
9 ........ it shows 9 for switch position 9
A ........ it shows A for switch position A
B ........ it shows B for switch position B
C ........ it shows C for switch position C
D ........ it shows D for switch position D
E ........ it shows E for switch position E
F ........ it shows F for switch position F
