L ND R MIDI line driver - master & slave pair Operating manual
Description The LNDR MIDI line driver is supplied as a pair of units with a MIDI Input and a MIDI Output at both ends to enable you to connect MIDI devices to each other over much greater distances than is usually possible using standard MIDI cables. A MIDI signal applied to the MIDI IN of the master will appear at the MIDI out of the slave. Similarly a MIDI signal applied to the MIDI IN of the slave will appear at the MIDI out of the master. You can send signals in both directions at the same time.
Troubleshooting Check that you are using a properly wired CAT5 cable – see above. Check that you are using a “straight through” cable, not a “crossover” cable. Check that the “active” LEDs are lit. If you encounter problems at very long distances, it could be the result of volt-drop in the CAT5 cable, in which case substituting the power supply for a 12 or 15 volt unit type will help. Note that we have tested the LNDR system to over 750 metres using the supplied PSU without problems.
