Product Query: The product query string immediately follows the header. The header for a
request about product ABC would be:
Byte # 0 1 2 3 4 5 6 7
0 0 0 12 P R O D
The query string “ABC” and a terminating <NUL> immediately follow the
header. Mode settings can cause the client to send its unit ID and a <TAB>
character before the product data, and/or add terminating <CR> and/or <LF>
characters at the end of the query string.
Data: Data can be one of several types. The data–type token immediately follows the
packet–type token, and the data follows after that. The header for a data packet
to display the word “hi” would be:
Byte # 0 1 2 3 4 5 6 7 8 9 10 11
0 0 0 15 D A T A T E X T
The data string “hi” and a terminating <NUL> immediately follow the header.
Registration: Registration information consists of three sequential <NUL> terminated strings
following the header. The first string is the unit ID, the second is the product–
type identification, and the third is the IP address of the registering client. The
header for a registration packet for “Entry”, product type “SCANVUE5
®
200102161901”, and IP address of “10.0.0.227” would be:
Byte # 0 1 2 3 4 5 6 7
0 0 0 79 R G S T
Each registration string and its terminating <NUL> immediately follows the
header or the previous registration string. When a client receives a registration
packet, it should respond by sending its own registration.
