Adapter for Symbol MC9000-G Readers
This adapter communicates with a custom software program hosted on the Symbol
MC9000 device. This adapter opens a server socket over TCP and listens for
connections from the Symbol MC9000-G device. The data payload consists of one or
more lines of text with two possible formats containing the data fields as shown in
the following table.
■ Format A – "tag,count\n". An example of Format A looks similar to the following:
■ H40001403EA000001,1
■ H40001403EA000002,3
■ H40001403EA000028,15
In this example, the adapter receives three 64-bit EPC tags from the reader. The
first tag was detected once, the second tag was detected three times, and the third
tag was detected fifteen times. In release 3.0, the adapter ignores the count, and
does not pass it to the event listeners.
■ Format B – "timestamp,tag,classType,count\n". An example of Format B looks
similar to the following:
■ 2005-07-15T11:23:10-05:00,H40001403EA000001,C1,1
■ 2005-07-15T11:23:13-05:00,H40001403EA000002,C1,3
■ 2005-07-15T11:23:20-05:00,H40001403EA000028,C1,15
