Figure 8: SIM card inserted
Insert the SIM card from the rear into the card slot (in the lid), so that the gold contacts face
downwards in the closed end and the beveled side is at the open end of the lid.
Click the lid shut again and gently slide the metal bracket outwards.
Connect the modem plug back to the power supply.
i
In case of an EK280 with an internal power supply, the mains voltage must not be switched back
on again at this point, otherwise damage to the internal power supply and the internal modem
may take place.
i
There are two plugs on the modem board for the power supply to the modem (see Figure 6).
Always connect the battery or the internal power pack to the plug labeled with "battery",
otherwise the modem will not work.
The plug labeled with "Uext" is provided for future enhancements and cannot currently be used.
Screw the EK280 housing back on.
b) If necessary, unlock the SIM card (enter the PIN)
If the inserted SIM card's PIN ("Personal Identification Number") is activated, carry out the following instructions
to unlock it:
Move the cursor to the "
Serv.
" tab in the EK280's display, then to
Interfaces > internal modem > GSM and GPRS > PIN
Press the
ENTER
key and enter the first PIN digit using the
and
arrow keys.
i
The PIN must be entered right-aligned in the EK280!
Move the cursor through the next digits using the
key and enter them.
After entering the last digit press the
ENTER
key, to save the input.
Under "
P.Sta
" the "
Pin New
" is now ready for confirmation.
If "
P.Sta
" is not displayed, move the cursor down using the
arrow keys.
As soon as a communications time window is opened via the modem, the new PIN is used. After a
few seconds, under "
Ant.P
" the message "
PIN OK
" is displayed if the correct PIN was entered, or the
message "
PIN Error
" if the PIN was incorrectly entered.
i
Further commissioning steps are necessary, before the mains power is switched on again on an
EK280 with mains power unit.
