4. Operation of UMX-OPT-TX150R
UMX-OPT-TX150R uses some of the standard timings for the RS-232
control and pass-through mode. To work the bidirectional serial
communication well between serial ending devices users must
choose the proper baud rate on the transmitter units. Please read
the serial devices' user's manual to find the appropriate baud rates.
The best one is both devices' most common value.
If the communication speed ability of a serial device is unknown use
the lowest (#1: 9600) value.
Available BAUD RATE rotary values:
Rotary switch position
#0
#1
#2
#3
#4
#5
#6
#7
#8
#9
INFO: When all the front panel LEDs are blinking, they refers to the
undefined baud rate settings (baud rotary switch is set from #5 to #9).

The system consists of the following: a Blu-Ray player and a laptop
Not used
as sources, a programmable touch panel as a controller, then a
Not used
Lightware UMX-OPT-TX150R and HDMI-3D-OPT-RX150R as the optical
Not used 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
RS232=Pass / Control
on and off the projector, and switch between the inputs. Let's examine
KVM (under development)
the detailed solution.
Three types of the touch panel's commands:
HDCP
Autoselect
LINK
S/PDIF
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:
