6. Network Bridge Function
This projector is equipped with the NETWORK BRIDGE function to perform 
mutual conversion of a network protocol and a serial interface.
By making use of the NETWORK BRIDGE function, a computer that is connected 
to the projector via wireless or wired LAN is able to control an external device via 
RS-232C communication using the projector as a network terminal.
6.1 Connecting devices
1)  Connect the projector’s LAN port to the computer’s LAN port with a LAN 
cable, or insert the USB wireless adapter into one of the  USB TYPE A ports.
2)   Connect the projector’s CONTROL port and the device’s RS-232C port with 
an RS-232C cable, for RS-232C communication.
• Before connecting the devices, read the manuals for the devices 
to ensure the connection. 
For RS-232C connection, check the specifications 
of each port and use the suitable cable. (

6.4 Transmission method
6.4.1 HALF-DUPLEX The transmission method can be selected from the menus, only when the 
NETWORK BRIDGE is selected for the COMMUNICATION TYPE.
(
&OPTION menu > SERVICE > COMMUNICATION in the Operating Guide )
HALF-DUPLEX   FULL-DUPLEX
This method lets the projector make two way communication, but only one \
direction, either transmitting or receiving data, is allowed at a time.
The method does not allow the projector to receive the data from the com\
puter 
while waiting for response data from an external device. After the projector 
receives the response data from an external device or the response limit\
 time is 
past, the projector can receive the data from the computer.
That means that the projector controls transmitting and receiving the da\
ta to 
synchronize the communication.
To use the HALF-DUPLEX method, set up the RESPONSE LIMIT TIME following 
the instructions below.
Using the RESPONSE LIMIT TIME menu, set the waiting time for response data 
from an external device.  (
&OPTION menu > SERVICE > COMMUNICATION 
in the Operating Guide )

• With using the HALF-DUPLEX method, the projector can send out 
254 byte data as maximum at once.
• If it is not required to monitor the response data from an external device and 
the RESPONSE LIMIT TIME is set to OFF, the projector can receive the data 
from the computer and send it out to an external device continuously.
The OFF is selected as the default setting.
• In case that the computer controls to synchronize transmitting 
and receiving the data, it may not be able to control an external device\
 well 
depending on the processing status of the projector. NOTE
NOTE
6.4.2 FULL-DUPLEX
This method lets the projector make two way communication, transmitting \
and 
receiving data at the same time, without monitoring response data from a\
n 
external device.
With using this method, the computer and an external device will send th\
e data 
out of synchronization. If it is required to synchronize them, set the computer to 
make the synchronization.
