8 „ERR" LED (red)
This LED is used as „Error" LED and will inform of activities or errors according to the chapter on description of
the error codes and LED flashing sequences.

11 Position of the GPS receiver in the housing
To warrant best GPS reception, the GX111 must have a free view of the GPS satellites in the sky.
e) Description of the USB socket
This connection is used to charge the rechargeable battery of the device with a charging current of 100 mA. This does
not require drivers and any commercial USB plug-in mains unit can be used.
A higher charging current (500 mA) requires release from a USB host (e.g. PC with USB-port). Only then will the
charging times described in the technical data be available.
Data communication takes place via a standard USB chip that signs on to the Windows-PC as a virtual COM port.
The corresponding driver can be procured either from www.conrad.com or directly from the manufacturer's website:

f) Notes on Use

• There is no prescribed usage position.
• When using the USB socket, observe that there is enough room for the plug. Lateral forces on the plugged-in plug
can lever the socket from the PCB and thus cause irreparable damage, loss of warranty/guarantee!
• To warrant the device function, choose a site of use where the GMS network reception is as good as possible and
the GPS signal can be received.
• The product should be taken to a site where object shock can be measured („SHOCK" alarm).

g) Notes on Connection

• The external cables must be kept as short as possible and remaining line lengths must not be coiled. The maximum
line length is 3 m.
• Too-strong temperature fluctuations may lead to temporary impairment and require manual reset in extreme cases.
• The product is not intended for the „Safety" area and also does not correspond to any SIL/ASIL level.
