2. Start M300 and setup the system for either acquisition mode (See “Acquiring Data” on page 80)
or playback mode (See “Playback Data” on page 82).
3. Click on the Toggle Broadcast button and make sure it’s depressed (See “Command Bar” on
page 61).
4. If the M300 is not in play mode, make sure you click on the play button (See “Command Bar”
on page 61).
Once you click on play and the broadcast button is clicked other systems in the M300 in UDP mode
should start to see the data. To see how to setup the M300 to run using UDP mode (See “UDP” on
page 84).
If the systems using UDP are not seeing the data, then we need to start the troubleshooting for this.
1. Usually the first thing to do is to check and make sure the systems are connected together. The
M300 systems should be connected to Giga bit hub when possible (specially if are concerned
about network speed issues).
2. You can use netinfo -l to see information about the network card. Both the receive and
transmit sides should have a value for number of total packets. If these are 0, then this would be a
problem.
3. You can use the alive command to see if the QNX 4 machines are on the network (this assumes
all machine have different node numbers and are connected).
4. Use the ping to see if machines in the TCP/IP side of things can see each other.
5. Possible missing network ports in the /etc/services file.
6. For instructions on the TCP/IP setup (See “QNX Setup for M300 UDP Operations” on
page 43).
UDP
To use M300 system is in UDP mode is fairly easy.
