6-7-2. Remote control input connector (REMOTE IN) (Stereo mini)
Connected with the projector’s remote control the accessory remote cable.
When the remote cable is connected to this connector, the remote cable connector operates with the following functions.
DC power supply unit for remote control
Remote signal unit
GND unit
The DC voltage supplied from the projector to the remote control is approximately +4.0 V.
NOTE
The remote control cable is connected first to the remote control, then to the projector head.
The leading end of the remote control cable is the power supply unit, so be careful not to touch the other end
of the remote cable to the projector head or other devices while only the remote control cable is connected to
the projector.
TIP
Even if the remote cable power supply unit and GND unit (such as the projector head) should short, the
protective function inside the projector will activate to prevent the shorted cable from damaging the projector.
6-7-3. LAN port (LAN-A, LAN-B) (RJ-45)
Use Ethernet 10Base-T/100Base-TX UTP (Unshielded Twist Pair cable) to connect with a video server or a PC.
A switching hub exists inside, so there are no functional differences of either the LAN-A or LAN-B ports.
