10. Troubleshooting Guide
This section presents a selection of questions and answers that might be relevant to Multi-link SpaceWire
Recorder problems.
I cannot make a TCP/IP connection to my MSR unit.
 Make sure that the MSR unit is powered on and that the Ethernet cable is plugged in [at both
ends!].
 Are you attempting to connect from the host computer to the IP address of the correct MSR unit? Run a
ping test to make sure that your host computer can talk to the MSR unit.
 Look at the front-panel display of the MSR unit to confirm that the IP address shown is the one that you
are expecting to use. Check all of the digits very carefully...
 Check your network configuration to make sure that there is a viable IP route from your host computer to
the unit - maybe using tracert or traceroute.
 Does the MSR unit’s front panel display show “L” for listening, before attempting to run the msr
program, and “C” when it is connected?
 Is the Ethernet “R” (receive) indicator on the front panel display flashing occasionally, as broadcast traffic
is seen on the network?
I cannot monitor traffic on one of the MSR unit’s ports.
 Does the MSR unit’s front panel display show that the link is connected? Are the “R” and / or the “T”
indicators flashing for this link? If just the “N” and “X” indicators are lit continuously, one side of the link is
trying to connect repeatedly, without success.
 How many ports are supported on your MSR unit? Don’t try to use ports that are not available. Click the
front-panel switch up (or down) to discover the number of ports on your unit.
 There is a small chance that your SpaceWire cable is broken. Alternatively, one of the connectors may be
damaged, or not be seated properly, or the cable may not be connected to the correct port on the MSR
unit.
 Is the device-under-test properly wired and powered up?
 Are the SpaceWire port pairs being used properly? Link signals should be connected between ports 1 & 2,
3 & 4, 5 & 6 and 7 & 8 of the MSR.
 Install a loopback connector on one of the ports in the pair and run a simple loop-back test to the other
port in the pair, to ensure that it is connecting properly.
 Use the 4Links SpWIO program on an ESL or DSI or SRR unit to connect to the device-under-test
manually.
