ALPHA BEAM 1500
Switching on the projector
- Fig. 8
Press the switch. The projector starts resetting the effects. At the same time, the following information scrolls on the display:
Model Firmware xxx (Fixture ID) System errors
Alpha BEAM Version X.X.X Dmx Address xxx E: .........................
1500 Date - Hour W: .........................
On conclusion of resetting in case of the absence of dmx signal, Pan and Tilt move to the “Home” position (Pan 50% - Tilt 50%). The control
panel (Fig. 8) has a display and buttons for the complete programming and management of the projector menu. The display can be in one of
two conditions: rest status and setting status. When it is in the rest status, the display shows the projector’s DMX address and the Fixture ID
address (if set).
During menu setting status, after a wait time (about 30 seconds) without any key having been pressed, the display automatically returns to rest status.
It should be noted than when this condition occurs, any possible value that has been modified but not yet confirmed with the
key will be cancelled.

Connecting to the control signal line (DMX)
- Fig. 7
Use a cable conforming to specifications EIA RS-485: 2-pole twisted, shielded, 120Ohm characteristic impedance, 22-24 AWG, low capacity. Do not use
microphone cable or other cable with characteristics differing from those specified. The end connections must be made using XLR type 3 or 5-pin male/female
connectors. A terminating plug must be inserted into the last projector with a resistance of 120Ohm (minimum 1/4 W) between terminals 2 and 3.
IMPORTANT:
The wires must not make contact with each other or with the metal casing of the connectors. The casing itself must be connected to the
shield braid and to pin 1 of the connectors.
