VIA IR PORT
Make sure the mobile computer's infrared port is pointed directly to the infrared port
of another IR device.
Make sure the distance between the mobile computer and a target device is within
proper range, and no obstacles in between. Try to establish connection again.
If the problem persists, run the Echo Test to check if the IR interface between the
mobile computer and the cradle is working. (See
3.3.6 Echo Test.)
USING RS-232 CABLE VIA CRADLE
Check if the RS-232 connection is correct and secured.
Make sure the serial port parameters on the host are configured to match the serial
parameters on the mobile computer. Try to establish connection again.
Make sure the mobile computer is well seated inside the cradle. DO NOT remove the
mobile computer or disconnect the cradle before communications are done.
If the problem persists, run the Echo Test to check if the IR interface between the
mobile computer and the cradle is working. (See
3.3.6 Echo Test.)
VIA BLUETOOTH
Make sure the distance between the mobile computer and a target device is within
proper range. Try to establish connection again.
Check if the relevant settings are correct. (See 3.9 Bluetooth Menu — 8062.)
If the problem persists, run the Echo Test to check if the connection is working
properly. (See
3.9.4 Echo Tests.)
VIA WI-FI
Make sure the mobile computer is connected to an access point properly, under the
same SSID. Try to establish connection again.
Check if the relevant settings are correct. (See 3.10 Wi-Fi Menu — 8071.)
If the problem persists, run the Echo Test to check if the connection is working
properly. (See
3.10.5 Echo Tests.)
VIA ETHERNET CRADLE
Check if the Ethernet connection is correct and secured.
Make sure the networking parameters are configured properly. Try to establish
connection again.
Make sure the mobile computer is well seated inside the cradle. DO NOT remove the
mobile computer or disconnect the cradle before communications are done.
If the problem persists, run the Echo Test to check if the Ethernet connection is
working properly. (See
3.8.3 Echo Tests.)
