Equipment Required; Procedure - Enfora Enabler LPP G Integration Manual

7.8.2. Equipment required


Temperature chamber

Mostly discharged battery or battery simulator.

A notebook or desktop computer with any version of Microsoft Windows that has the
HyperTerminal communications program. If this hardware is not available, the user could use
a DOS terminal emulation program.

7.8.3. Procedure

This is a procedure for setting the AT$BCITMP# parameters, assuming a 10kohm NTC
temperature sense resistor is used.
Step Action
1 Set
temperature
averaging.
2 Set current
to 30uA
3 Reset the
modem
4 Start debug
traces
5 Cycle
charger off,
on.
6 Ensure
battery is
charging
7 Set temp.
8 Set
temperature
parameters
9 Restore
averaging
10 Reset the
modem
11 Verify
temperature
readings
Repeat procedure for AT$BCITMP2-AT$BCITMP5, as required.
