CHAPTER 4. ADJUSTMENTS
1. ADJUSTMENT PREPARATIONS
(1) Wiring
1 Connection of Power Supply
• The power supply can be connected to up to 3 units in a series using the AC outlets of Multi projection units. Connect the
three units as one system to the external outlet.
• The AC plug of Multi projection unit is a 3P with a ground pin. When connecting it to a normal outlet, use an exclusive 3P AC
adapter.
• The AC plug of Multi projection unit is a 3P with a ground pin. To prevent electric shocks, connect the ground pin to the
ground when connecting the power supply.
2 Connection of signal cable
• Use coaxial cables. Normally, if less than 15m, use 3C-2V. If less than 30m, use 5C-2V.
The signal transmission equipment and Multi projection units should be as close as possible to each other.
3 Connection of ABL link cable
• By connecting the ABL link cables in cascade form, control signals (RS-232C, remote control signal) can be transmitted to all
the units.
RS-232C
Personal Computer
or
Remote control
(2) Wiring Handling
• Except for short-term installations such as events, etc., in normal long-term installations, adjust the length of the wiring
appropriately taking into consideration the overall route to be wired.
• Make sure the connection terminals are not subjected to direct weight and force. Tie the wires up in short-term use and bind
them up properly in long-term use.
(3) Aging
• After turning on the power, input the 100% white signal or moving images, and perform aging until Multi projection unit
stabilizes (about 1 hour). If adjustments are performed without performing aging, as Multi projection unit will warm up and
stabilize, convergence and white balance will become incorrect.
