The polling command format is the following:

When the PWD22 unit number two (ID=1) is polled for message
number 3 (status), the command format is the following:
PW 1 3
This format can be used in all cases.
Use character 1 as the ID if the ID has not been set but a specific
message type is polled. This is to enable the PWD22 software to
distinguish the ID from the message number.
The PW command can be used, if only one PWD22 unit is on the
line (no ID is set) and the default message is wanted.
PWD22 does not echo the polling character string.
The answer message format is the following:
PW id text
Negative or zero interval is used to disable
