Blackmagicdesign MultiView Series User Manual

The RS-422 serial port is configured as 9600 N81:
9600 is the line speed, or baud rate, at 9600 bits/sec.
N represents no parity check, or ‘none’.
8 is the data length.
1 is for stop bits.
To summarize N81, data without a parity check begins with 1 start bit, includes 8 true data bits,
and 1 stop bit. There are 10 bits in total.
The protocol is line oriented, with a maximum length of 250 characters per command. Each
command from the client should be terminated with a carriage return (\r). Each response from
the server will be terminated with a carriage return and line feed (\r\n).
Sources, destinations and levels are always specified in base-16, numbered from zero. Levels
are always between 0 and 15 (“F”) . Blackmagic MultiView 16 only has one valid level –
level zero.
On connecting to the serial port, the client should send a carriage return. Blackmagic MultiView
16 will respond with a
> character prompt, which is not followed by a carriage return or line feed.
Receiving the prompt indicates that a connection has been established. The same prompt will
be issued after each command received by the MultiView.
In the following documentation, commands in
orange and values in blue must be typed literally,
including any spaces. In the following example of an immediate command using destination
port 7 and source port 3,
@ X:0/destination,source would be entered as: @ X:0/6,2
The RS-422 serial port lets you control Blackmagic MultiView 16 from third party routers and
automation systems. The connector is an RJ11 connector, the same used in many landline
telephone connections. By modifying an RS-422 to USB adapter cable terminated with an
RJ11connector, you can control Blackmagic MultiView 16 using external controllers via USB.
An RS-422 to USB adapter cable and RJ11 connector can be purchased
from electronics stores such as Digi-Key.com. Refer to the pinout
diagram below for help wiring the RJ11 connector to the adapter cable.
