Installation Manual LOGS50 EN_MI_090221
Reset the primary battery cell %BATERY to 100% value after changing
primary battery cells.
Check that unit works correctly by implementing serial communication
with the unit.
For rechargeable accumulator replacements apply the same protocol ignoring
the %BATERY resetting.
1.6 EXTERNAL POWER SUPPLY
As an alternative to the internal lithium batteries, LOGS50, as said earlier, has
an external power connector (COM-POW) that permits the device to work using
a commercial external power supply simultaneously with the internal batteries
as backup. The electronic circuitry always chooses the highest voltage available
to function.
Before connecting an external power supply, consult the specifications section
and verify its compatibility. The average power consumption of the device is
low; however, some task involving GSM -GPRS- 3G communications require
certain current peaks that not any external power supply can provide.
The external power supply must be connected observing the polarity on the
cable.
1.7 GSM / GPRS /3G MOBILE COMMUNICATIONS
LOGS50 for mobile communications with base stations utilizes the GSM cellular
network thanks to a GSM/GPRS/3g module that permits digital information
transfer. This transfer is mostly realized in two ways:
Via Short messages, known as SMS- used to send information related to
alarms to mobile phones. Use decaying.
Internet communications using IP addresses and TCP/IP sockets.
The module incorporated has associated a SIM card that identifies the
telephone number assigned to the LOGS50. This card is a Standard element for
mobile communications and there is a large amount of telecommunication
companies that offer multiple choices and modalities of payment. The election
of one or another modality is the user responsibility. Nowadays M2M data
services are preferable.
The logger does not manage the modality of the SIM card. It is the
responsibility of user to follow the conditions imposed by the mobile
communications company.
