CHAPTER FIVE - CONECTIVITY

RTS/CTS handshaking mechanism to clear the medium, meaning that a
station use RTS/CTS handshake before sending an actual message frame.
The ‘RTS Thresh’ tells the WLAN driver on your PL3000 that the RTS/CTS
handshake shall precede the transmission of the frames being longer than the
value set to the ‘RTS Thresh’. The standard says that the RTS threshold
should be set to 2347 bytes, meaning in practice that the RTS/CTS feature is
disabled because the maximum value of the ‘Frag Thresh’ is 2346 bytes. Thus,
to enable the RTS/CTS feature on your PL3000 the value of the ‘RTS Thresh’
shall be below the value of the ‘Frag Thresh’.

Certs Path:
The Certs Path tells the SDC Supplicant (not the WZC) where to
find a CA (Certificate Authority – the issuer of the server certificate) certificate
to check that the network is trustworthy when the authentication server sends
its certificate. Before keying in any directory name into this field, be aware that
the SDC Supplicant uses the default directory as a certificate store as follows:
\Windows\ Programs\Summit\Certs. Try first to upload and store the required
certificate in that directory without specifying the Certs Path. Over and above,
be aware that you have to tap on a ‘Validate Server’ checkbox to be checked
when you define your WLAN profile in the SCU, so that the SDC Supplicant
verifies the validity of a server certificate. By default the SDC Supplicant does
not prove WLAN trustworthiness on an EAP-based port authentication.
Miscellaneous Global Settings Assigned to SCU Utility
•
Tray Icon:
This is an on-off switch to enable or to disable whether or not the
SDU Supplicant icon is in view in the annunciator area on the taskbar.
•
Hide Password:
It is possible to disguise sensitive information such as WPA-
PSK or WEP key information in the SCU fields using this global parameter.
The Hide Password is an on-off switch. You can see the result of the change if
you check the value of an Admin Password.
Note!
The Hide Password has the significance only when SCU settings
are password protected. By default that is not the case. If you want to lock
the SCU settings with an admin password, please contact NordicID’s
technical support and ask how to enable the ‘Admin Password’ protection
in the SCU utility.
•
Admin Password:
In the field of the Admin Password you can key in the
administrator password of the SCU utility. Default password is ‘SUMMIT’.
However, the SCU settings are not password protected by default, so the
Admin Password has no meaning before the feature of the administrator
password in the SCU is enabled. To enable the admin password, see the text
box above.
Settings of SCU Ping Utility on ‘Global’ Page
On the ‘Diags’ page in the SCU utility there is a button to start pinging some
IP-address. The settings below apply to that feature of the SCU.
