The Address mode is set to Binary (2B LSB first), the Address mask is
set to 7FF0 and the Address position is set to 2. The SCADA message
starts with bytes (in hex) 02 DA 92 C3 .. The 2-Byte address is read as
0x92DA (note the LSB came first in the message), Then 0x7FF0 mask
is applied and the resulting value 0x12D0 (0x92DA & 0x7FF0) is used
as the input for the translation.

Poll response control
List box: On, Off
Default = On
On
– The Master accepts only one response per a request and it must
come from the the specific remote to which the request has been sent.
All other packets are discarded. This applies to the Master - Slave
communication scheme.
Note: It may happen, that a response from a slave (No.1) is delivered
after the respective timeout expired and the Master generates the re-
quest for the next slave (No.2) in the meantime. In such case the delayed
response from No.1 would have been considered as the response from
No.2. When Poll response control is On, the delayed response from the
slave No.1 is discarded and the Master stays ready for the response
from No.2.
Off
– The Master does not check packets incoming from the RF channel
- all packets are passed to the application, including broadcasts . That
allows E.g. spontaneous packets to be generated at remote sites. This
mode is suitable for Master-Master communication scheme or a com-
bination of the UNI and ASYNC LINK protocols.
