RS232
An Electronic Industries Association (EIA) serial digital interface standard specifying the
characteristics of the communication path between two devices using either D-SUB 9 pins or D-
SUB 25 pins connectors. This standard is used for relatively short-range communications and does
not specify balanced control lines. RS-232 is a serial control standard with a set number of
conductors, data rate, word length and type of connector to be used. The standard specifies
component connection standards with regard to computer interface. It is also called RS-232-C,
which is the third version of the RS-232 standard, and is functionally identical to the CCITT V.24
standard. Logical '0' is > + 3V, Logical '1' is < - 3V. The range between -3V and +3V is the transition
zone.
RS422
An EIA serial digital interface standard that specifies the electrical characteristics of balanced
(differential) voltage, digital interface circuits. This standard is usable over longer distances than
RS-232. This signal governs the asynchronous transmission of computer data at speeds of up to
920,000 bits per second. It is also used as the serial port standard for Macintosh computers. When
the difference between the 2 lines is < - 0.2V that equals with a logical '0'. When the difference is >
+0.2V that equals to a logical '1'..
USB port
The communication interface is equipped with a master USB port, type "A" connector. This USB port will
simplify the service procedures for firmware updates or for downloading the log files without a network
connection.
If the only file on the USB device is the firmware file (a "*.fw" file), the projector will automatically start one of
the following processes.
•
cornet<version nr>.fw: The projector will upgrade or downgrade, depending on the version number.
•
LogExtractor.fw: The log files will be downloaded.
Make sure that any used USB-stick is FAT32 compatible and contains no other files or folders.
3.4 Input source connections – Quad combo input
Mark II
About the Quad combo input Mark II
Due to demand from the market, Barco has created a second generation of the Input board to support 12G
input and throughput on the SDI connectors. From the release of this board onward, the Quad combo input will
be supported and will be the standard input board in every Input & Communication Unit, effectively replacing
the Mark I variant.
The updates on this new board include the following compared to its predecessor:
•
SDI Input A now also supports 12G input signals.
•
SDI Input C now also functions as a loop-through output for any signal placed on Input A.
•
SDI Input D now also functions as a loop-through output for any signal placed on Input B.
•
HDBaseT Input 1 now also supports network connectivity.
SDI Input & output – How does it work?
When connecting an SDI source to the projector and the signal is HD or 3G, you can choose any of the four
input connectors.
When connecting multiple projectors with the same signal, you can connect the signal as follows:
•
Connect the source signal to Input A or B of the first projector.
•
If the source signal is connected to Input A, connect Input/Output C to the Input of the following projector.
•
If the source signal is connected to Input B, connect Input/Output D to the Input of the following projector.
•
Continue in the same fashion until all projectors are connected.
