UART Settings
The BC840-MC uses a Universal Asynchronous Transmitter/Receiver (UART) for data
transmission. The UART recognises and reproduces the words in the data stream. This is only
possible if the UART is programmed to understand the serial data format.

Description
Bit rate
1200, 2400,
4800, 9600,
19200, 38400,
57600,
115200 bit/s.
The speed of the digital transmission - that is, the
amount of information transferred/processed per
unit of time.
Word length
(excluding parity)
5, 6, 7, 8.
Determines the number of bits that is transferred in
a single operation.
Stop bits
1, 2.
Indicate the end of a data character to enable the
receiver to resynchronise with the stream.
Parity mode
None, Even,
Odd, Mark ,
Space.
Enables sending of an extra bit with each data
character for error detection purposes.

Make data connections
Data RS-422/485 > MX Transmitter/Receiver Settings
After selecting a data mode (see General Settings) and configuring the interface (see UART
Settings), data link configuration is done in the same fashion as described for video links.
To configure a data link
1
In the Transmitter Settings section, set at least one destination IP address.
2
Set a port number or leave it at the default.
3
Enable the stream.
4
Click SAVE to write the new configuration to the device.
The data interface is bidirectional in the sense that apart from a streams transmitter, a
receiver is available on the same unit. However, the data transmitter and receiver are
independent of one another, except for the data interface settings.
Do not forget to enable both the transmitter and the receiver, and to configure the UART
correctly (see Advanced Settings).
