Z1 Operating Manual
Z1 Operation
For diagnosing MIDI transmission and distribution related problems we recommend
fitting both a 5 pin DIN plug and a 5 pin DIN line socket with an LED soldered across
pin 4 and 5, with the anode to pin 4, so that the LED body just protrudes through the
cable support.
These testers may be used to check that MIDI data is being transmitted by substituting
them for the receiving equipment. They should not be used in parallel.
Starting with a MIDI source, plug the line plug into its MIDI Out and observe the LED
flicker when MIDI data should be sent. Replace the normal MIDI cable and plug the
line socket into the other end to check that the cable is not faulty. Pin 4 shorted to pin
5 or to the screen will cause this LED to be permanently off, whereas pin 5 shorted to
screen will cause the LED to be fully on.
Work along the MIDI data route until you are sure that data is being presented to the
Z1 MIDI input. Using a short XLR cable connect the Long Haul output back to the Long
Haul input and check that the Receive LED is flickering when data is sent.
When you are satisfied that the Long Haul output is transmitting, follow a similar
process at the receiving unit to the destination MIDI equipment. If the Receive LED
is flickering but the MIDI equipment behaves strangely, this could indicate a phase
inversion in the XLR cabling. Otherwise, check that the MIDI equipment is set up for
transmitting and receiving on the same MIDI Channel and that the relevant Modes and
Status types are enabled.
The Z1 Long Haul Converter should give years of fault free operation—many Hinton
Instruments Long Haul Converters have been in continuous use for over ten years or
used on major international tours and events—but it has been designed for ease of
servicing in the event of any component failure.
Spare components and sub assemblies are available for critical maintenance
applications. Please enquire if you need this support.
