5.6.3 Configuration
(read) Whenever the AMS-8061 connects to GPRS and accesses to FTP, it looks
for a file named
8061.CFG in its directory (its serial number). If the file is
present, the AMS-8061 retrieves it and calculates the checksum in order to
use it and thus get the new configuration. If the checksum is wrong, the file
is discarded otherwise the new configuration is taken.
Is important to note that the new setting will not take effect immediately but
only after the connection is closed.
All figures are Little Endian notation unless differently specified.
The structure of the configuration file is as follows.
Pos Name Size
Byte Type Description
0 ChkSum 2 Unsigned int Check sum (see the related paragraph)
2 idstation 34 Char The name of Station. This is a null terminated string.
36 Mask
alarm 2 Unsigned int
Being Bits this is
BIG endian
The mask of Alarm is a bit mask where ‘1’ means Alarm
Enabled while ‘0’ is Alarm Disabled. Here is a list alarms.
0x0001-> MAX threshold Field OUT.
0x0002-> Warning threshold Field OUT.
0x0010-> LOCK OUT.
0x0080-> Low Battery Voltage OUT
0x0004-> Antenna OUT
0x0020-> Temperature
0x0040-> Relative Humidity
0x0008-> MAX threshold Field IN.
0x0100-> Warning threshold Field IN.
0x0400-> LOCK IN.
0x0800-> Low Battery Voltage IN
0x0200-> Antenna IN
38 Reserved 1 Unsigned char None
39 AvgRms 1 Unsigned char The way of averaging. If ‘AvgRms’ is 0 then is arithmetic
average otherwise is Root Mean Square
40 MaxThr 4 Float A little endian floating point figure that represents Max
threshold used for Alarm.
44 WarnThr 4 Float A little endian floating point figure that represents
Warning threshold used for Alarm.
48 Logger 1 Unsigned char This parameter sets the rate of the logger as follows
“1” ->1 minute
“2” ->2 minutes
“3” ->6 minutes
“4” ->15 minutes
49 reserved 1 Unsigned char None
50 Naver 2 Unsigned int This parameter represents the averaging time for
Warning and Alarm threshold. It is expressed as 4 times
the averaging time. For example a 6 min time is reported
as 24
52 GPRS
Appoint 2 Unsigned int This parameter represents the scheduled time for
connecting to GPRS of the day. It is expressed in
minutes elapsed since midnight.
For example the schedule 12:30 would be (12*60)+30
=750
54 GPRS
Ton 1 Unsigned char This parameter represents the time the GSM remains
ON after a GPRS connections. It is expressed in quarter
of hour.
