4.4.3.3 Sensors (continued)
End Character – This means that the iServer will send a character (in Hex) after the
value for each variable. This will apply to either Continuous or Command mode. Once the
value is selected, it will be a global change for all readings. The default is set for 0D (Hex
representation of <CR>).
Description – This can be a name for the sensor or where the sensor is located. This
field is text only and can have up to 16 alphanumeric characters. This description will
appear wherever Reading 1, 2 or 3 is displayed on the web server.
Unit – This would be the units of measurement for that particular sensor. Examples are
% for humidity, F and C for temperature and dewpoint. Once the unit of temperature is
selected, either C or F, it will be a global change through out the web server, as well as
on the LCD display. If you use the front C/F buttons to change the unit of temperature it
will have no affect on the web pages.

Display – If checked the variable (i.e. temperature) will be displayed on the Readings
and Chart applets as well as data transmission in Continuous mode (see Server Section
4.4.3.2). The default is checked.
Data Format – This indicates the format of the variable being displayed on a network
host when Continuous or Command transmission is used. Reading 1: T000.0C, 000.0C,
000.0; Reading 2: H00.0%, 00.0%, 00.0 (the C or F will change to the appropriate unit
once you press Save Changes button).
Adjust by – If it’s determined that the reading is slightly off this field can be used to
adjust the reading. The options are Offset and Scale & Offset. Using the Offset method
you can manually assign a numerical value to adjust
the reading. For example if the actual reading is 55
where it should be 54 you can enter -1 in the Offset
field. The Scale & Offset method uses two points
to adjust the reading within the entire temperature
range. For example, if at the lower point the actual reading is 10 where it should be
12 and at the higher point the actual reading is 200 where it should 195, here is how
the numbers are entered. The adjusting numbers can be positive or negative with one
decimal point.

The adjusting values
must be assigned
after the unit of
temperature (C or F)
is selected. If the unit
of temperature is
changed, you must
readjust the values
for a correct result.
