If a firmware update is required, con firm that the image of the supplied update matches
your model. If the equipment has expansion keyboards connected, it is not necessary to
disconnect them. Proceed as follows:
•
Connect the equipment to the NEO system.
•
Use the Con figuration software, search and select the MPS in the devices list and
you can send the firmware file through the PC.
6 FAULT RESOLUTIONS
6.1 THERE IS NO LINK WITH THE SYSTEM
The system will indicate link fault when it detects that the transmission route has a
shortcircuit or is disconnected.
Check that the equipment where is connected the ACSI bus (NEO Controller) is working
properly, try connecting just one unit in the ACSI bus with a short cable to discard problems in the
cable.
Check that only the last element in the bus has the option “END of Bus” activated,
according to chapter 4.2.1
Connect the auxiliary power supply included with the equipment in case that the MPS-8Z
is powered directly from the ACSI bus.
Check that the connection between the equipment and the system was correctly
perfromed as indicated in chapter 4.2.
RESET the unit (the equipment must be con figured again). In this case, press
simultaneously the buttons “CANCEL”, “EVENTS” and “MEMORY” for 5 seconds. The equipment
will restart. Con figure the address accordingly (see 4.2).
If this procedure does not work, disconnect the unit from the ACSI bus and contact LDA's Support
Department. Once the unit is removed, if there are more units connected in the bus, connect the
inputs and outputs lines of the ACSI bus in order to keep the system functioning in normal
operation.
6.2 STATE LED INDICATORS BLINK simultaneously
The system will indicate address fault in the ACSI bus when there are two or more units
with the same address.
Con firm that the unit's address is correct, in order to do this, follow the steps indicated in
chapter 4.2
RESET the unit (the equipment must be con figured again). In this case, press
simultaneously the buttons “CANCEL”, “EVENTS” and “MEMORY” for 5 seconds. The equipment
will restart. Con figure the address accordingly (see 4.2).
If this procedure does not work, disconnect the unit from the ACSI bus and contact LDA's
Support Department. Once the unit is removed, if there are more units connected in the bus,
connect the inputs and outputs lines of the ACSI bus in order to keep the system functioning in
normal operation.
6.3 NO LED INDICATOR IS ON
If this is the case, probably there is a problem in the power supply.
If the unit is being powered over the ACSI bus, disconnect the unit from the bus and
connect the auxiliary power supply included with the equipment. The unit will then start the test of
the led light indicators.
