If, in the case of an EK260 V2.4x, the modem reset function should be used together with an
active PIN, the time windows in the EK260 must be set in the following way:
a) Time window 1 (call acceptance) must be open at 00:00 o´ clock
b) Time window 2 (modem reset) must be open shortly before 00:00 o´ clock
Reason:
The EK260 V2.40 sends the PIN query command (AT+CPIN?) only at 00:00
o´clock and only if time window 1 is already open at 00:00 o´ clock !!!
Example of setting for the time windows:
Time window 1 (call acceptance): 23:59 to 23:55 o´ clock
Time window 2 (modem reset): 23:55 to 23:56 o´ clock
Parameter file for cyclical modem reset
If a cyclical modem reset is to be carried out and if all conditions for its use are fulfilled (see
above), a special parameter file has to be loaded into the EK260. The name of the parameter file
to be used depends on the software version of the EK260:
“EK260_
y
v
y
.. - Funktion=Modem-Reset täglich EM260_x.WPP“
(where
y
v
y
= software version of the EK260, e.g. 2v5 and x = latest file index)
)
For a cyclical modem reset, output 4 of the EK260 must be connected to the modem
reset input! (

Wiring instructions for cyclical modem reset
If a cyclical modem reset is to be carried out and if all conditions for its use are fulfilled (see
above), the wiring between the EM260 and the EK260 must be modified as follows:
EK260 clamp
Signal direction
EM260 clamp
Uext +
Å
+9V
Uext -
not connected
GND
Wavecom-Adapter-Board V1.1 or higher
+9V
DA4+
Æ
Switch
DA4 -
not connected
)
If output 4 of the EK260 is connected to the modem reset input, it is absolutely necessary
to load the corresponding parameter file into the EK260 !!! (
