Rs-232 Control Port; Alarm Outputs (Receiver) - Lightware DVI-OPT-TX220-Pro User Manual

2.3.3. RS-232 control port

Devices can be remote controlled through industry standard 9 pin D-SUB female connector
located on the rear panel of the unit. Please use a standard RS-232 Male to Female cable
(straight through).
RS-232 port settings on the PC:
9600 Baud, 8 data bit, 1 stop bit, no parity

2.3.4. Alarm outputs (receiver)

TTL outputs can be used to give a signal to any third party device. Separate signals indicate
the detected laser and the presence of the received DVI signal.

Table 2-2. D-sub connector pin assignment for standard RS-232
DVI signal present
+5 V
Laser detected
Indicates when a valid DVI clock signal is extracted from the fiber
optical signal. Logic 1 (+5V) means that a DVI signal is detected.
Logic 0 (GND) means that a valid DVI signal cannot be extracted
from the optical signal.
Indicates when a laser beam is detected at the Neutrik connector.
Logic 1 (+5V) means that a laser beam with the appropriate
wavelength is detected. Logic 0 (GND) means that either there is
no laser signal or its level is too low to be recognized.
Ground reference signal for alarm outputs. Connected to chassis
ground.
