(1) Wiring
1 For the power supply
¶ For the power supply, up to three units can be connected in a series using the multi projection units' AC
outlets. Use different external power outlets for each set of three units.
¶ The multi projection unit's AC plug is a 3-pin plug with a ground pin. When connecting the power supply, be
sure to connect the ground pin to the ground in order to prevent electric shocks.
2 Connection of signal cables
¶ Use coaxial cables. In general use 3C-2V cables for lengths of up to 15 meters, 5C-2V cables for lengths of up
to 30 meters. Keep the distance between the signal transmitter and multi projection unit to a minimum.
3 Connection of ABL linking cables
¶ Control signals (RS-232C and remote control signals) can be sent to all units by connecting the ABL linking
cables in cascade form.
