5.4.5. Detailed example
Figure 5-4. Example system diagram
The system consists of the following: a Blu-Ray player and a laptop as sources, a
programmable touch panel as a controller, then a Lightware UMX-OPT-TX150R and
HDMI-3D-OPT-RX150R as the optical extenders, then a projector as a sink device. The
touch panel has three buttons. The desired functions of the buttons are that they can
power on and off the projector, and switch between the inputs. Let’s examine the detailed
solution.
Three types of the touch panel’s commands:
( ): settings of the touch panel / not sent /
[ ]: command to the projector / sent via RS-232 to UMX-OPT-TX150R then via fiber
optical cable to the projector /
{ }: command to the UMX-OPT-TX150R / sent via RS-232 to UMX-OPT-TX150R /
Initializing:
First of all the touch panel can control the projector only if RS-232 settings are the same
for the touch panel and the projector.
Commands: Comments:
(set_RS-232) /* Set the appropriate RS-232 settings which are fit to
the UMX-OPT-TX150R and the projector as well. */
Info: 57600, 38400, 19200 or 9600 Baud, 8 bit, 1stop bit, no parity. These settings are fit to the
UMX-OPT-TX150R.
Button 1 (Power on the projector):
The touch panel can control the projector only if the UMX-OPT-TX150R is in
pass-through mode.
{RS232=PASS} /* Set the UMX-OPT-TX150R in pass-through mode */
[projector_on] /* Power on the projector */
Button 2 (Select the HDMI input):
The touch panel can only control the UMX-OPT-TX150R if that is in control mode.
Commands: Comments:
{RS232=CONTROL} /* Set the UMX-OPT-TX150R in control mode */
{4@1 AV} /* Select the HDMI input on the UMX-OPT-TX150R */
Button 3 (Power off the projector):
The touch panel can control the projector only if the UMX-OPT-TX150R is in
pass-through mode.
Commands: Comments:
{RS232=PASS} /* Set the UMX-OPT-TX150R in pass-through mode */
