transmitted. If this transmission mode option is selected, the modem will send the data when it
receives it after a selectable time delay. This allows users to continue to fill the buffer even if
there are gaps in time for data sets. Just set the delay time for something greater than the
largest gap in the data set. The buffer will hold 8k bytes.
“Send data based on __% of full buffer”
In this field, the user can select the % of full buffer before the modem transmits the data in its
buffer. Since the buffer holds 8k bytes, if 1% is selected, the modem will transmit the data once
82 bytes are received.
“Send data based on __data bytes”
In this field, the user can select the exact amount of data in bytes before the modem transmits
the data in its buffer. Since the buffer holds no more than 8k bytes, the user must be sure to not
overrun this as well as be absolutely sure of the amount of data being sent from the externally
connected device to appropriately use this transmission mode.
“Send last data set with current data set”
This option enables data redundancy. If selected the previous data string will be included in the
current data string. This is used to insure that the data makes it to its destination if a data drop
out occurs.
“Use GPS Time and Date”
If this is selected, the modem will update its clock with the time it gets from the GPS satellite
given in UTC time.
“Cell-Net Internal Data”
The modems internal data can be set to prepend the data every time there is a transmission.
The user can select all of the parameters of interest or have none selected. The user has a
choice of Battery Voltage, GPS latitude and longitude, internal temperature, MEID, date and
time stamp, and RSSI. For example, if all of the parameters are checked and the data is
“My_Data123456” the data string will look like this:
MEID=A10000,32B89CE4,
TIME=23:07:26,
DATE=18/03/14,
RSSI=-081,
BATT= 011.845,
TEMP= 027.683,
LATT=4534.1007N,
LONG=12232.1531W,
My_Data123456
