Before connecting
z
Before connecting, carefully read the operating instructions of the devices to be connected.
z
Turn off the power of all devices before connecting cables.
z
Connect 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 inuenced by a noise. If the cable is used in a wrapped condition, it becomes an antenna,
which more easily gets inuenced by a noise.
• When connecting the cable, insert to the connecting terminals of the interface box perpendicularly,
connecting to GND rst.
z
If 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.
z
Video 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.
z
The interface box accepts video signals, S-video signals, analog RGB signals (synchronous signals are TTL
level), and digital signals.
z
Some computer models are not compatible with the interface box.
z
Refer to “List of compatible signals” (
page 48) for the input image signals that can be used for the interface
box.
