4.1.10 Final reception test with installed data cable
The final reception test is necessary for two reasons: First to ex-
amine the assembly position of the WIMAN, second, and more
importantly, to test the data link between the Router and the
WIMAN.
You will find details to the reception tests in chapter 6 on
page 58.
To perform the test, connect your Laptop to the RS232-interface
at the Hybrid-cable type 2.
If there is no connection to the WIMAN or if the connection is
unusually slow, follow the instructions specified below to locate
the source of error.
1. Make sure that the terminal program is adjusted to the cor-
rect Baud rate (9600 Bit/s).
2. The power-LED lights up in green when sufficient operat-
ing voltage is supplied, and in orange if the WIMAN per-
forms a looptest. If an internal error occurred the power
LED lights up in red.
3. Make sure that the RS-232 cable and the power-supply are
correctly connected at both ends of the data cable.
4. Double-check the solder joints and the pin-allocation inside
the plugs of the data cable.
5. Check the hybrid cables by alternating them one at a time.
4.1.11 Check the statistics of the X.21-interface
To check the statistics of the X.21-interface you must first test
the connections between the WIMAN and the Router.
To test the connections you must:
1. Ensure that Router is attached correctly and switched on.
2. Enter the instruction "stat serial ext".
This instruction displays information to the data transmitted
via the Serial-interface. The last line of the display-output
should look as follows.
Line State: Control (C): ON Indication (I): ON
If “OFF” appears in either of the signals, a connection error has
occurred. Follow the instructions given below to locate the
source of the error:
1. Check the X.21-connections at both ends of the data cable
for correct fit.
