+Messages needed, expressed as communications from OPI board to main board
+Message format information:
+            Messages are encoded as variable length binary data with CRC-16 validation
+
+Mainboard will provide acknowledgement response. If nak reponse or no response after timeout OPI board may request again.
+
+ 
+
+ 
+
+Record format (records to and from mainboard):
+
+ 
+
+Byte
+
+ 
+
+1          Multidrop address (record length)
+
+ 
+
+<message>
+
+...
+
+ 
+
+(record length – 2)      CRC-16
+
+ 
+
+ 
+
+[[BR]]Message formats:
+
+(If mainboard detects CRC fail for any request response message will be 15h <eeee> (eeee = error code))
+
+(Second byte of request identifies scale/analog, serial port number, option card slot number for many requests)
