DMX LINE TERMINAL
Do not connect or wrongly connect the DMX line terminal is probably the most common cause of a defective
functioning of a DMX line.
The DMX line terminal is a resistance placed between the two data pin 2 and 3 at the end of the line.
The terminal resistance should ideally have the same value of the impedance of the DMX connecting cable.
On the MH-250 is inserted a resistance value of 100 Ohm that can be started by a switch placed on the base rear panel
(fig. A).
!It is suggested for all DMX systems to use a DMX line terminal (DMX line terminator ON, fig. A) only on the
last connected unit.
!Usually the DMX connection is insulated from the unit mass. In some cases (very rarely) it is suggested to act
in a different way. On the base rear panel there is a switch that connect electronical the two masses (DMX Gnd).
Use this switch (DMX Gnd ON, fig. A) only if the DMX line functioning is not stable although connection and
termination are correct.

DMX SIGNAL CONNECTION
The DMX signal connection to the MH-250 must be done through the input signal connectors XLR 5 pins, placed
on the rear panel of the projector (fig. 5).
The nomenclature of the pins of the DMX input connectors is listed in the table reported in fig. 5/a.
To avoid any problem in the transmission of the signal it is recommended to use a cable for very fast data transmissions.
A normal audio cable is suitable only for lines long not more than 100mt.
The best performances and the maximum stability are obtained using a shielded microphonic cable which section
must be of at least 2x0,25mm, or, a data transmission cable.
In case of lines long more than 150/200mt. it is recommended to use a DMX Repeater Amplifier.
On the MH-250 control panel (fig. 6) besides the display there are some led and buttons which allow the projector
correct configuration.
LED
• Led “DMX” flashing: the DMX input signal is On;
off: the DMX input signal is Off..
• Led “LAMP OFF” flashing: the control board lamp is Off;
off: the lamp is On.
BUTTONS
There are four buttons which allow the complete programming and management of the projector:
• MENU allows the selection of the
programming options;
• DOWN allows to run the selected options

16 BIT MODE SELECTION
Press the MENU button on the control panel until the nChn option will appear on the display: pressing the ENTER
button, the mode already set will appear (10, 11 or 13 channels). For a better 16 BIT performance , it is necessary
to set 13 channels on the display. Press the DOWN or UP button until the preferred number will appear. Then
memorize it pressing and holding the ENTER button, untill the display stops flashing (the flashing shows that the
option selected is different from the one already set).
To leave the option without changes press the MENU button.
The MH-250, selected for 16 BIT operating, needs 13 channels to check its functions.
The relation between channels and functions is described in the following table:
For the complete DMX values see APPENDIX “B”, page 36.
ADDRESS SELECTION
Press the MENU button on the control panel until the Addr option will appear on the display: pressing the ENTER
button, the predetermined channel will appear. To change it use the DOWN or UP button following the example of
fig. 8. When the preferred channel has been reached, memorize it pressing and holding the ENTER button, until
the display stops flashing (the flashing shows that the option selected is different from the one already set).
To leave the option without changes press the MENU button.
The flashing “DMX” led on the panel shows that the data transmission between DMX control and projector is
working.
In fig. 8 are indicated the correct channels numbers to use four MH-250 (16 BIT, 13 channels) in DMX 512.

BOARD MOT250 (fig. 9)
PROBLEMS AND SOLUTIONS
• All the three led indicate that there are voltages and signals coming from the base circuits:
+30V and +5V come from the board POWER250 (pages 23-27);
DMX comes from the panel board DMX250 (pages 29-30).
To locate the trouble if one of the voltages is not present (for example led +5V off) check that it is off even on the
board POWER250:
+ 30V
+ 5V

2) if the led on the board POWER250 is on, it is necessary to carefully check all connections between the
differnt
boards. Probably a cable is interrupted or one connector is not inserted correctly.
1) if the led is off on the board POWER250, disconnect the circuit MOT250 disconnecting the connector.
If the led still is off, go on with the instructions on page 23 - “POWER SUPPLY BOARD”.
If the led starts, the trouble (probable a short) is located on the circuit MOT250.
In that case, make sure that there is an overheating component. Where possible take it out from the base
and give voltage to the circuit. If the led starts, replace the component.

• If one of the Stepper Motors does not move (i.e. the GOBO wheel):
1) put off the projector and disconnect the connecting cables of the GOBO and COLOUR wheels.
2) connect the cable of the GOBO wheel to the connector of the COLOUR wheel.
3) start on the projector:
3a) if the motor of the GOBO wheel works properly, it is necessary to replace U5 (L6219).
3b) if the GOBO motor still does not work, it is necessary to carefully check it, so as all the connections
circuits (cable and connectors). For a correct check of cables and motors it is possible to effect the
following resistor test:
• between pin 1 and pin 21 (on U5) r =6 ÷ 18 Ohm;
• between pin 2 and pin 5 (on U5) r =6 ÷ 18 Ohm.
