4.6 Communication Connections
Overview
• RS232 (RS422) Connection
• Linked System
• Communication with peripherals
• Network connection
4.6.1 RS232 (RS422) Connection
Application
1. Remote control :
- easyadjustment of projector via an IBM PC (or compatible) or MAC connection.
- allowstorage of multiple projector configurations and set ups.
- widerange of control possibilities.
- addressrange from 0 to 255.
2. datacommunications : sendingdata to the projector or copying the data from the projector to a hard memory device (hard disc,
floppy,etc.).
Set up of the Baud Rate for communication with a computer.
see "Baud rate Setting", page 107.
4.6.2 Linked System
CAUTION:Alwaysuse the Barco COM 800 Splitter, R9827941 (240V) or R9827948 (110V), when using the COM
800 protocol.
What can be done?
Ina complex multi-channel setup, projectors can be controlled using the RS232 or C OM800 Protocol.
CLOcan be controlled by both p rotocols, however by using the COM800 port for this adjustment, the RS232 Port can still be used
for general RS232 commands.
Thefollowing procedure will describe how to connect COM800 Linked System.
How to connect a COM800 Setup
Alwaysuse the Barco COM 800Splitter, R9827941 (240V) or R9827948 (110V), when using the COM 800 protocol.
1. Usea data cable with at least 9 cores and 2 DB9 female connectors, just cross the pin 2 and pin 3 connection to make a Custom
Null Modem Cable. (image 4-8)
2. Usethe Custom Null Modem Cable to connect the COM 800 port of the master-projector to the ’To Switcher’ port on the frontside
of the COM 800 Splitter. (image 4-9)
3. Continueby connecting the slave projectors to the ’To Proj.’ connectors on the backside of the COM 800 Splitter (image 4-9).
4. When dealing with more than 4 slave projectors, t he ’ToProj.’ connectors on the backside of the COM 800 Splitter can also be
used to connect extra COM 800 Splitters (image 4-9).
