25
x1
device address: 0...255
The tens (
x
) in the address value (from 0 to 25) are represented by one
of the following ASCII symbols: 0123456789:;<=>?@ABCDEFGHI,
and the ones (
1
) (from 0 to 9) – with 0...9 respectively.
The address may be obtained from the warranty card or
from the device information level (parameter
Addr
)

15.2.3. Example
At receiving a command for deactivating output K1,
a device with address 100 answers with
@:021100000078*#13,
where #13 is an ASCII symbol with code 13,
and all symbols to the left are ASCII.
