Connection problems
Both types of connection (VIATOR modem and FXA520) should function without any faults or
interruptions. If you notice any communication failures (values in the DD are colored red), please
check your connections as shown below.
7.2.1
VIATOR Bluetooth modem
In case of connection problems, please try the following measures:
• Shut down Device Xpert application.
• Switch off the VIATOR Bluetooth modem.
• Wait 10 seconds.
• Switch the VIATOR Bluetooth modem back on.
• Wait 10 seconds again.
• Start the Device Xpert application again, and try to open the COM port.
• Ensure that you have specified the correct serial port for your Field Xpert hardware.
If these measures do not help, please check that there is still enough charge in the batteries of the
VIATOR Bluetooth modem (see Section 4.3.3). If less than 10 % of the charge is remaining, this
may result in the connection being disrupted.
7.2.2
Fieldgate FXA520
In case of connection problems, please try the following measures:
• Shut down Device Xpert application.
• Disconnect from the internet.
• Wait 10 seconds.
• Activate the internet connection.
• Wait 10 seconds again.
• Check the Fieldgate connection and authentication settings (IP address/host name, user name,
password) which you configured.
• Restart the Device Xpert application and try to establish a connection (scanning).
If these measures do not help, please check your Fieldgate FXA520.
More information on this can be found in Section 9 of the Operating Instructions for the FXA520.
7.3
Software problems
In the case of software problems, please try the following measures:
• Shut down Device Xpert application.
• Disconnect all Bluetooth and internet connections, and switch off the Field Xpert.
• Wait 10 seconds.
• Switch the Field Xpert back on.
• Activate the required connection.
• Restart the Device Xpert application and try to establish a connection (scanning).
If no device is found, check that the electrical connections and the circuit load correspond to the
specifications listed in the manual provided with the device. If these measures do not help, carry
out a soft reset. To do this, press both soft reset keys (see fig. 3-1) at the same time until the PDA
starts again.
