15 Frequently Asked Questions
Can the WiFi data logger be connected to the PC using any USB cable?
We recommend that you use the USB cable supplied with the WiFi data logger
to guarantee stable data transmission. Longer USB cables are suitable for the
power supply only.
Can the WiFi data logger also be used in networks with WPA2 Enterprise
encryption?
Second-generation Saveris 2 loggers* can be used in networks with the
following WPA2 Enterprise encryption methods.
EAP-TLS, EAP-TTLS-TLS, EAP-TTLS-MSCHAPv2, EAP-TTLS-PSK,
EAP-PEAP0-TLS, EAP-PAP0-
MSCHAPv2, EAP-PEAP0-PSK, EAP-PEAP1-TLS, EAP-PEAP1-
MSCHAPv2, EAP-PEAP1-PSK
To integrate the loggers into the WPA2 Enterprise network, proceed as follows:
1. Open the .PDF file stored on the logger and generate a corresponding .XML
file by selecting the programming options step by step.
2. Copy your company-specific WPA2 Enterprise certificates and the generated
.XML file to the logger's mass storage via USB using drag & drop.
3. Please pay special attention to the correct spelling and to the suffixes of
certificate names.
ca.pem, client.pem, private.key
Check whether the certificate is available in a PEM or BASE64 format. To do so,
open the certificate using a text editor and check that you can see the string “-----
BEGIN CERTIFICATE-----”. If you cannot see this string, the IT department or the
user must explicitly export the certificate from the Radius server using BASE64, or
convert it using openssl. There must be one certificate only, not a bundle, inside the
file.
4. Please note that the configuration of the WiFi data logger will only be fully
transferred once the USB connector has been removed.

The XML configuration file is not being applied by the WiFi data logger,
what can I do?
Depending on the operating system, there may be difficulties with the data
transfer if the configuration file name has been changed. Leave the default file
name.
The WiFi data logger's wireless connection to the access point was
interrupted, what can I do?
• Press the control key on the WiFi data logger to start searching for a
WLAN connection manually.
• Change the alignment or position of the WiFi data logger or the access
point (WLAN router).
