Antennas (only on selected products)
If the device is equipped with a radiotelecommunication device the respective signals are available on standard SMA or SMA-RP connectors,
depending on the radiotelecommunication technology.
Important
Note
Maximum cable length allowed for antenna connections is 2.8 m. If longer cables are used, special
overvoltage and filtering elements must be installed to comply with the requirements of EMI/RFI "CE"-
certification. Only use high quality industrial devices with sufficient EMI compatibility.

Internal connectors
CMOS Battery
The CMOS battery supplies the necessary power required to maintain the CMOS settings and configuration data in the UEFI flash
chip. The specified battery type is CR2450N(3V, 540mAh) or CR2477(3V, 950mAh). Because the self-discharge of all lithium batteries increases
rapidly at high temperatures the battery life time decreases by a great amount. To prevent battery leakage scheduled service/replacement is
recommended. Please contact the battery manufacturer for further details and calculation assistance for battery life time calculation.
Fuse
The main fuse protects the system against destruction in case of high energy distortions on the power line. For replacement, the system must be
opened in an ESD protected environment. Only an entitled instructed person is allowed for this operation. Replacement fuse type is Littelfuse
452004.MRL (4A slow-blow).
USB 2.0
Depending on the installed PC board the PROTOUCH-WIDE-R offers several internal USB connectors whereof one is used to connect the
touchpanel. Please contact technical support for further details and assistance.
