A
The
Supported
field indicates what firmware revision this protocol will work
under. Most protocols, especially straight ASCII ones intended for DVD or CD
players will work since rev 5.00. If the device requires firmware modification to
work, the
Protocol
field will be changed to that new type, and the rev number
of the
Supported
field will indicate that version of firmware. If a user
attempts to use this protocol, and downloads to a Show Controller with firmware
prior to this field, a compile/download error will alert the user that this unit will
not support these commands.
The
Type
field is currently for information only, but will eventually be used as
a description when a user right clicks on a protocol and selects "Properties". Try
to match this field with other similar devices in other Protocol files. There is no
right or wrong text to put here.
The
Interface
field determines what kind of device it is, and what kinds of
fields will follow. The two current possible choices for Interface are Serial
and SCSI . If the
Interface
is Serial , then the
DataBits
,
StopBits
,
Parity
, and
BaudRate
fields should follow. If the interface is SCSI , then the
Address
field should follow.
The DataBits field ( for Serial only ) determines the number of bits in the serial
data frame used for data. The three possible choices for
DataBits
are 7 , 8, and
9 . If the device supports multiple types, then separate them by commas.
The StopBits field ( for Serial only ) determines the number of bits in the serial
data frame used as an end-of-frame marker. The two possible choices for
StopBits
are 1 and 2 . . If the device supports both types, then separate them
by commas.
The
Parity
field ( for Serial only ) determines whether or not a parity bit exists
in the serial data frame used for parity checking, and if so, whether it is even or
odd parity. The three possible choices for
Parity are N , E , and O . If the device
supports multiple types, then separate them by commas.
The
BaudRate
field ( for Serial only ) determines the speed of transmission of
the serial frame bits in bits per second. The possible choices for BaudRate are
300 , 1200 , 2400 , 4800 , 9600 , 19200 , and 38400 . In the case of a MIDI serial
port, the only possible choice is 31250 . If the device supports multiple types,
then separate them by commas.
The Address field ( for SCSI only ) determines what address the SCSI device
is set to. The possible choices for Address are 0 , 1 , 2 , 3 , 4 , 5 , 6 , and 7 . If the
device supports multiple types, then separate them by commas.
The
Protocol
field determines what method the Show Controller uses to send
out the bytes. For example,
the Alcorn9 protocol type tells the Show Controller to turn on the ninth bit on
the first and last bytes of each message. The possible choices for
Protocol
are
Alcorn9 , Alcorn8 , Custom , ReproBus , DVD , MIDI , ESERTC , and SonyCDROM .
Only one of these should be selected here. In general, most users will choose
the
DVD , Custom , or MIDI protocol type. The only difference between DVD
and Custom is that the Show Controller expects to have tight communication
with the device, and often expect Acknowledges back from the device.
