“Recipient” and “Polling” panels
The first operation to do is polling; this will verify the connection status of the intended target PCN-1001.
To do this, Insert the appropriate address in the Recipient box and then click the Start button.
If the appropriate PCN-1001 is found, the address is correct and the port is configured correctly, the software will
display a message like: “Got reply from [Slave #2]”.
Otherwise the following message will be displayed: “Timeout expired!!!” In this case, you must verify the settings
and try again.
For each command that has been sent to a PCN-1001, the
RS485_GUI waits for an answer.
Three kinds of answer are available:
RESPONSE DESCRIPTION
[Slave #2] sled
The PCN-1001 has received the “sled” command followed by the LED level (see “RS485 Protocol”)
and replied with the string: “sled”.
Got corrupted reply!!!
The RS485_GUI could not understand the answer.
Timeout expired!!! The signal has been lost and the RS485_GUI did not receive any answer.
Flag “Broadcast” for sending a message to all the PCN-1001 devices connected (i.e.: for setting the same time
and date to all the PCN-1001)
When a message is sent in broadcast mode, the PCN-1001 devices will not reply.
