Acquisition Modules and Platinum Firmware
Transmitting Data
Network
The WIN transmitter can be configured to be either a TCP server to multiple
clients, or a UDP sender to a single address. If you want to sent the data to
multiple clients, set up the acquisition module as a TCP server and the
remote machines as clients that connect to it.
Protocol: To configure the sender as a TCP server, select “TCP server
accepting multiple clients” from the drop-down list.
Hostname: To use a specific IP address to listen for requests from clients, set
this in the box. By default it will listen on all interfaces.
Service: Set to the port that you want the server to listen on in the box.
If you only want to send the data to a single UDP server, select “UDP
datagrams sent to specified address” from the Protocol drop-down list.
Configure the remote machine's hostname or IP address in the Hostname box
and set the port number that the remote machine will listen on in the Service
box.
Max delay: The WIN sender will buffer up data before it is sent so that
outgoing packets have a second's worth of data from all channels. If no data
are received from some channels within a certain time limit, the data from
other channels will be transmitted anyway. This limit is specified by the
value in the field and defaults to five seconds.
Early transmit size: If a packet in construction exceeds the size specified the
packet will also be sent early.
UTC Offset: The WIN Format uses the local time in order to time-stamp
packets. The offset of the local time-zone from UTC used in the GCF data is
specified in the box.
