Chapter 2 __________________________________________________________ MEASUREMENTS
There are several parameter options you can set in the
Communications frame of the Measurements view. Note that,
in general, the predefined settings are the most suitable for a
typical MAWS setup.
In order to change a parameter option, you simply need to select
or unselect the corresponding check box. The following options
are available:
-
Use the Device ID (editable) text box to distinguish
HMT33. For information on how to change the device ID,
see Vaisala HUMICAP® Humidity and Temperature
Transmitter Series HMT330 User's Guide.
-
Select the Mode in which HMT330 is operated. When you
select the Cyclic transmit mode, HMT330 automatically
sends data at predefined intervals. If you select the Polled
mode, MAWS polls HMT330 at predefined intervals to
retrieve data.
-
In the Polled mode, by using the timeout parameter you can
define the maximum length of time allowed for HMT330 to
reply.
-
In the Cyclic transmit mode, with the communication
timeout parameters you can define a maximum interval
between two messages. If the new message from HMT330
has not been received within the given time, the data in that
message is then marked as invalid.
Using HMT330 Variables in Reports
You can use the variables received from HMT330 in MAWS Lizard
like those from any other sensor.
To check which variables are available, proceed as follows:
1.
Go to the Reports view.

CHAPTER 3
COMMUNICATIONS
This chapter provides information on the new communication option,
Iridium satellite transmitter, how to interface the Iridium satellite
transmitter to MAWS, and more specifically, how to use the Short
Burst Mode in binary transmission.
Iridium Satellite Transmitter
Iridium transmission using data calls can be used like any other
modem. Thus, it has been possible to communicate through Iridium
with MAWS in earlier release versions as well.
Iridium is the only data solution with a complete coverage of the Earth
including oceans, airways, and Polar Regions. Iridium delivers the
essential communications services to and from remote areas where no
other form of communication is available. The Iridium constellation of
66 low-earth orbiting (LEO), cross-linked satellites operates as a fully
meshed network and is the largest commercial satellite constellation in
the world.
Short Burst mode (SBD) is a mechanism to deliver short data
messages over the Iridium satellite network to the Internet. Each SBD
message can be up to 1960 bytes in length.
For more information about Iridium communication, refer to
www.iridium.com.

Scaling parameters define how the data item will be scaled into the
binary report:
-
Unit conversion, specifies whether the value will be
converted to other units, for example from Celsius degrees
to Kelvin. This parameter functions in the same way as in a
regular report.
-
Offset option, indicates whether some offset value is added
to the value (after a possible conversion).
-
Multiplier option, indicates whether the value is multiplied
(after a possible conversion).
If scaling is used, the following formula applies:
New value = (value + Offset)⋅Multiplier
VAISALA________________________________________________________________________ 33
Technical Reference_________________________________________________________________
Data parameters define how the data value is coded in the binary
report, for example how many bits are used:
-
Data encoding, specifies the type of the value. The
parameter options are the following:
Parameter Option
Unsigned integer
Integer
Float
Double
BCD
-
Description
Presents the value as a positive

encoding range as the invalid value
specifies the highest value in the
encoding range as the encodable
value
-
Field width, defines how many bits are used to encode the
value. It is possible to use less bits than the data encoding
value would require. For example, if 11 bits are used for an
integer, only those 11 bits are stored in the binary report.
-
Do rounding after scaling, indicates that the value is
rounded to the nearest integer (after unit conversion and
scaling).
-
Write absolute value of data, indicates that negative values
are multiplied by -1
- Write only sign of data, indicates that only a polarity bit is
displayed for data item. The polarity bit is zero if the data
34 ___________________________________________________________________ M210728EN-A

item is equal to or more than zero (positive value of the data
item). Otherwise the polarity bit is one (negative value of the
data item).
-
LSB written first, indicates that the number is displayed in
a reversed order (INTEL presentation)
-
Include parity bit, indicates that a parity bit is added to this
field to assure data validy. This option increases field length
by one. See below for a description of the parameter options:
Parameter Option
