P36
Temperature units mode
0
0 to 3
Units for all temperature measurements:
0 = ºC Celsius
1 = ºF Fahrenheit
2 = K Kelvin
3 = ºR Rankine
P38
Decimal point character ASCII
46
(.)
1 to 255
In CSV and free format mode (
/h
) data, this character is
used as the decimal point character. CSV data separator
automatically changed to ";" if this is set to comma (44).
P39
Time format mode
0
0 to 3
0 = HH:MM:SS.TTT
1 = decimal seconds since midnight
2 = decimal minutes since midnight
3 = decimal hours since midnight
P40
Time separator character ASCII
58
(:)
1 to 255
This character is used to separate HH, MM and SS fields
in time values.
P41
Time sub-second digits
digits
3
0 to 6
Sets number of decimal places in time values
P50
Time instant format mode
0
0 to 5
Specifies the format to use when returning an absolute
date/time value:
0 = P39P22P31 (time, delimiter, date)
1 = P31P22P39 (date, delimiter, time)
2 = decimal seconds since 1-Jan-1989
3 = decimal minutes since 1-Jan-1989
4 = decimal hours since 1-Jan-1989
5 = decimal days since 1-Jan-1989
P51
Time interval format mode
6
0 to 5
Specifies the format to use when returning a relative time
value:
0 = P39P22d.d (time, delimiter, days)
1 = d.dP22P39 (days, delimiter, time)
2 = decimal seconds
3 = decimal minutes
4 = decimal hours
5 = decimal days
6 = P39 format (hours may be > 24)
P53
Default serial sensor timeout seconds
10
0 to
30000
Max time that the DT80 will wait for a serial sensor input
or output action to complete.
May be overridden by channel factor
If P53=0 then characters satisfying the input action must
already have been received at the time that the input
action is processed.
P55
Enable schedule wakeup bitmask
16383
0 to
16383
bit 0 = not used
bit 1 set = wake from sleep if schedule X is due
bit 2 set = wake from sleep if schedule A is due
bit 3 set = wake from sleep if schedule B is due
…
bit 12 set = wake from sleep if schedule K is due
bit 13 set = wake from sleep if schedule S is due
By default DT80 will wake if any schedule is due.
P56
Diagnostic output bitmask
0
0 to
16383
Enable diagnostic output
bit 0 set (e.g. P56=1) – SERIAL channel
bit 1 set (e.g. P56=2) – SDI12
bit 2 set (e.g. P56=4) – Modbus
bit 3 set (e.g. P56=8) – FTP and SMTP
bit 4 set (e.g. P56=16) – Modem
P62
Retain multiplexer settings after
measurement
mode
0
0 to 1
0 = all terminals are disconnected from the DT80
measurement and excitation circuits at the end of
each scan
1 = connections are left set according to the last
measurement in the schedule. This can be useful for
verifying the DT80's excitation output, or for rapid
measurements of a single channel.

Switches
DT80 switches provide a further set of boolean parameters. Each switch is identified by a letter, and can either be on
(uppercase) or off (lowercase).
