PLICSMOBILE T81/B81/S81 • External GSM/GPRS/UMTS radio unit
55234-EN-170206
Data connections outgoing from PLICSMOBILE are established
via GPRS (volume-based billing). Outgoing connection are used
for measured value transmission via e-mail/SMS/VEGA Inventory
System.
During the transmission of the measured value via e-mail or Inventory
System, approximately 5 KB data are transmitted. With hourly trans-
mission, for example, this results in a monthly total net data volume of
approximately 4 MB.
The mobile network provider carries out a so-called block rounding
that depends on the selected tariff. When checking out of the GPRS
network, the values are rounded to next higher billing units. Since
PLICSMOBILE checks out of the GPRS network after the transmis-
sion of every message (if the energy saving mode is activated),
this block rounding applies to each transmission. If, for example, a
tariff with block rounding to 100 KB is used, an hourly measurement
transmission results in a monthly billing volume of over 70 MB. For
that reason, you should choose a pure data tariff plan (M2M) with the
lowest possible block rounding.
Insert the card (beveled side in front) into the card slot until it snaps in.
The contact surface must point upward.
Note:
The PLICSMOBILE T81 must be disconnected from voltage when
inserting the SIM card. Keep ESD protection in mind when handling
the SIM card. Electrostatic discharges can damage the SIM card or
the PLICSMOBILE.
