Connections

Before connecting

zzBefore connecting, carefully read the operating instructions of the devices to be connected. zzTurn off the power of all devices before connecting cables.

zzConnect the cables by paying enough attention to the following points. If not, troubles may be led.

Before start connecting a cable to the interface box or to a device connected to the interface box, touch a metal to release the charge from the operator’s body.

Do not use unnecessarily long cables when connecting the interface box and the projector. Longer the cable is, easier to be influenced by a noise. If the cable is used in a wrapped condition, it becomes an antenna, which more easily gets influenced by a noise.

When connecting the cable, insert to the connecting terminals of the interface box perpendicularly, connecting to GND first.

zzIf connecting cables necessary for the system connection are not supplied with the devices as accessories or not available as an option, prepare cables that are compatible to the connecting devices.

zzVideo signals containing too much jitter may cause the images on the screen to randomly wobble or wafture. In this case, a time base corrector (TBC) must be connected.

zzThe interface box accepts video signals, S-video signals, analog RGB signals (synchronous signals are TTL level), and digital signals.

zzSome computer models are not compatible with the interface box.

zzRefer to “List of compatible signals” ( page 48) for the input image signals that can be used for the interface box.
