How to deal with bi ­ directional communication
Keeping your system in sync with the PM1122 might look difficult but actually it isn’t if you follow
the right strategy. If you are writing a VB project or configuring a system like Crestron, you might
experience the same difficulty. What’s it all about?
When a preset is recalled or when a “GET INFO” command is executed, a big number of characters
are transmitted by the PM1122 ‐ INT. Possible receiving only a part of this string, will call your routine
which handles the received data. Although this string is not complete, it might already contain more
than one value. For example, a “GET INFO” command might call your receive handler 3 times. In the
next example, for clarity, a <CR> is represented by “\r” and <LF> by “\n”.
The first time the received string might be:” MSCLVL ZONE1 19\r\nMICLVL ZONE1 0\r\nSELECT
ZONE1 A\r\nRSRFFU ZONE1 0\r\nMAXMSC ZONE1 99\r\nMAXMIC ZONE1 60\r\nMINMSC ZO”. The
second time it is: “NE1 10\r\nMINMIC ZONE1 0\r\nMSCLVL ZONE2 0\r\nMICLVL ZONE2 0\r\nSELECT
ZONE2 C\r\nRSRFFU ZONE2 0\r\nMAXMSC ZONE2 80\r” and finally the last time it’s: “\nMAXMIC
ZONE2 100\r\nMINMSC ZONE2 0\r\nMINMIC ZONE2 0\r\nREMOTE ZONE1 1\r\nREMOTE ZONE2
1\r\n”
