AMR: For Automatic Meter Readings. This technology allows the value reading by radio waves. The main advantage of these solutions is to be able to obtain information on remote meters.
Autonomy: DIOPTASE carried out tests making it possible to compare the autonomy of the apparatuses of changing. For these tests, we prepare the mobile devices in an identical way (screen extinction duration adjustment, bluetooth activation, back lighting keyboard desactivation, using new batteries…) and let us install Quartz software. Periodic seizures are simulated by an automatic routine which makes it possible to make a meter reading every two minutes.
Technical details: During these 2 minutes, the writing lasts 30 seconds and back screen lighting remains lit during 1 minute. This test continues until the portable is not any more battery or it puts itself in safe mode.
Bluetooth: Bluetooth is a telecommunications industry specification. It uses a short distance radio technology intended to replace connections cables between electronic devices.
Memory Capacity: We express the mobile devices memory size in customer cards number. This figure corresponds to the customers numbers whom the device can contain. It depends on the mobile device and the removable memory card containing the software.
IP: Ingress Protection rating.
The IP Code defined the degrees of protection provided against the intrusion of solid objects and water.
It consists of the letters IP and 2 digits like: IP XY.

RoHS: The RoHS Directive stands for "the Restriction of the use of certain Hazardous Substances in electrical and electronic equipment". This Directive bans the placing on the EU market of new electrical and electronic equipment containing more than agreed levels of lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyl (PBB) and polybrominated diphenyl ether (PBDE) flame retardants. The RoHS Directive comes into force on 1 July 2006.
Manufacturers need to understand the requirements of the RoHS Directive to ensure that their products, and their components, comply.
RS 232 : RS-232 makes it possible to standardize a communication port of serial type. It is commonly called the serial port COM. On the operating systems, the RS-232 ports are often indicated by COM1, COM2,…
