15.5 Collecting data using Ethernet
The main purpose of the Ethernet connection is to collect measurement data from the
instrument. To program a downloading facility, see the specifications in the following
sections.
Vaisala guarantees that the specifications are correct, but cannot assume any
responsibility or provide support for software.
15.5.1 Communication protocol
The communication protocol is based on UDP/IP to port 50023. It is a client/server
protocol, where the DTR is the server and therefore only sends information when the client
(your computer) requests it. The server answers requests within 5 s (5000 ms), usually the
response time is below 100 ms.
Request format
The client to server communication (the requests sent from your computer to the DTR), is in
binary format. The request packets contain the following binary data (all integers are in the
network order, MSB first):
• 32-bit integer: packet number
• 32-bit integer: request ID
