ADDR Setting the transmitter address
ADDR aa <cr>
aa = address (0...99)
The address is used when more than one transmitter is connected to one serial
bus. The ADDR command makes it possible to communicate with one
transmitter at a time in POLL state.
For example, transmitter is given address 99
>ADDR <cr>
Address : 2 ? 99 <cr>
When asking the current address, no address number is given:
>ADDR <cr>
Address:2?<cr>
FROST Setting the calculation mode

FROST ON/OFF <cr>
This command is used to select whether the transmitter calculates the
frostpoint or the dewpoint (default) reading at dewpoint temperatures below
0 °C. Select FROST ON for frostpoint and FROST OFF for dewpoint
calculations. For example:
>Frost <cr>
Frost : ON
>Frost off
Frost : OFF
>Frost on
Frost : on
