Figure 2.32. RS232 Serial Link Loop-Through at First Projector
MIXED NETWORK
: To control multiple projectors with a computer/controller having
an RS422 interface, first set them all to the same baud rate as your RS422 controller.
NOTE:
You must enable this combination of RS422 and RS232 in the
Communications menu. Set the “Network Routing” option to “RS232 and RS422
Joined”. See
Section 3
for details.
Chain the projectors together by connecting an
RS232
port of the first projector
(already connected to the computer/controller through the
RS422
port) to an
RS232
port on the next projector in the chain. Continue connecting projectors in this manner
until you’ve reached the last projector in the chain, so that only the last projector has
one unused
RS232
port. See Figure 2.33.
Figure 2.33. Mixed Serial Network
Note that communication parameters such as baud rate must be set to match the
particular controlling device
before
connecting as a network—refer to the
documentation that came with your controlling device in order to determine the
proper baud rate. See
3.7, Adjusting System Parameters and Advanced Controls
if you
need help changing the projector baud rate. In addition, set the Network Routing to
“RS232 and RS422 Joined” if you want to reach all projectors.
NOTES:
1)
To avoid damage, connect only properly wired serial communication
cables. See
Appendix C
for details.
2)
It is recommended that each RS232
communication cable be no more than 25 feet in length. Use high quality cables.
