Davis consoles have their own proprietary protocols, for more details consult their
respective user manuals.
The ID of a specific sensor can be found using the attr -s command, under the
section “sensor ID (index)”, it is the value given in parenthesis. If there is only one
sensor configured in the RTU, then the ID is always 0.

Usage
dacq t <sensor_IX> <cmd> where <sensor_IX> is the ID of the sensor to send a

Remarks
Not all sensors support the transparent command. For SDI-12 <cmd> is a standard
SDI-12 command, including the exclamation point (!); for Davis consoles <cmd> is
a Davis command as described in the “Vantage Pro Serial Communication
Reference Manual” (see Davis Instruments web site http://www.davisnet.com); for
Thies <cmd> is a Thies command as described in the Thies TDL14 or DL16 User

Description
Historians command and subcommands, used to inspect the sensor data stored
in the local memory (data base).
Usage
hist [ -h | <cmd> ] with the -h parameter, the list of all subcommands will be
shown.
hist <hist#> <date> [<time>] Display the first 20 values stored for the historian
<hist#> starting with <date> and <time>. Without a parameter, the next 20 values
(or less if not so many are available) for the previously selected historian will be
displayed. The <time> parameter may be left out, in which case the time will be
automatically set to 0:00 for the specified day.
The hist subcommands are described in the following sections.
Remarks
To look-up the historian ID corresponding to a certain tag, use the hist map
command (see below).
Example
: hist 5 1/10/20
