10.2
Battery Charging
To prevent premature aging of the batteries it is good practice to always:
charge the batteries completely before re-inserting them into the APS-NR2.
use the batteries until they are discharged.
10.2.1
Using the external battery charger
The APS-NR2’s batteries can best be charged in the APS-NR2 external battery charger.
For a totally drained battery of 3400mAh a charging time of 3.5 to 4 hours can be expected.
10.2.2
Using the A/C adapter
The APS-NR's batteries can be charged while in the device using the wall charger.
If the batteries are being charged while the APS-NR2 is switched off, there is no visual indication of the charging, all LEDs on the APS-NR2 will be off.
When inserting the Lemo plug into the APS-NR2, the red dot has to point to the center of the device.
Insert the plug until the edge of the plug touches the connector.
Figure 28: Lemo plug
If the Lemo plug is not properly inserted, damage may occur to the electronics of the APS-NR2.
10.2.3
Using USB adapter
The batteries can be charged using the USB cable. The charging speed is very dependent of the quality of the charger. It is recommended to use the A/C adapter for charging the batteries in the unit.

11 System Administration using the Web Interface
The
Configuration
tab has five options: where user profiles can be saved and used upon startup,
Reset where the APS-NR2 can be reset,
Upgrade
Expert Console where the APS-NR2 can be upgraded, where line commands can be sent and specific data can
About a Diagnostic Report can be generated.
Further detail on each option is shown below.
11.1.1
Configuration
11.1.1.1
What is a configuration?
A collection of all settings and values that determine the behavior of the APS-NR2 are called a configuration.
The configuration that is actually being used is the Current configuration. If the user changes settings of the APS-NR2 using the Web Interface or the Expert Console these changes are stored in the Current configuration.
If the user wants to make the changes to the Current configuration persistent, the values of the Current configuration are to be copied to the Boot configuration.
Each time the APS-NR2 is started, it copies the Boot configuration into the Current configuration.
The factory defaults are stored in the RxDefault configuration. The user can enforce the
APS-NR2 factory defaults by applying a reset as described in section "11.1.2 Reset" on page 42.
When the APS-NR2 is used in different set ups requiring their own specific settings, the
APS-NR2 allows storing two user profiles or user configurations, User 1 and User2.
The user can store a configuration into a user profile by simply copying the Boot or the
Current configuration to User1 or User2.
To restore a user profile, the User1 or User 2 configuration is copied into Boot or
Current.

The batteries
12.3.1
Batteries
Altus supplies high quality 18650 3.7V Li-Ion batteries with the APS-NR2.
These batteries are available as spare parts.
The user may choose to buy spare batteries from another source.
Before buying spare batteries from another source, it is advised to read reviews of the batteries.
The battery specification must state that the batteries contain a protection circuit.
The cell inside the battery must be supplied by a well known brand (Panasonic,
LG, Samsung,...)
The warranty is void if the APS-NR2 is damaged by using low quality spare batteries
12.3.2
Charging
The APS-NR2’s batteries can best be charged in the supplied external battery charger.
For a totally drained battery a charging time of 3,5 to 4 hours can be expected.
The user may choose to buy a charger from another source.
Before buying a charger from another source, it is advised to read reviews of the charger.
Low quality battery chargers do not fully charge the batteries.
Battery chargers that can charge batteries of different technologies (e.g. Li-Ion and NiMH) typically do not optimally charge the batteries.
The APS-NR2's batteries can also be charged while they are in the device using the supplied wall charger.
Although the APS-NR2 can be charged using the USB communication cable, it is not advised. Depending on the design of the USB charger used, connecting the charger may stop logging to the internal disk.
Connecting the APS-NR2 to a USB charger may stop the logging.
4 8 | P a g e
12.4
Cell modem Commands
The APS-NR2 uses a Telit H24 cell modem.
Specific commands for the cell modem are described in H24 AT Commands Reference
Guide 80389ST10086a Rev.4 – 2013-02-19.
The Web Interface or the data collection software accompanying the product uses these commands to configure the modem.
It is not advised for the user to issue commands to the modem using e.g. the expert console.
Issuing commands to the cell modem using the Expert Console may cause malfunctioning of the device and will be considered improper use.
