simultaneously. Thus you could specify all the inputs going to a specific output (one column) or the value of an
input to all of the outputs (one row), but not the entire matrix. One example of using a wildcard for an integer
matrix command would be 'F04MGAINSG,*,0 '. This will set all the crosspoints in the signal generator row of
the main matrix to 0 dB. Thus, the signal generator will be added to all of the outputs of the main matrix with a
gain of 0 dB. In this case a status message will be generated that looks like
'F04MGAINSG,*,ääääääääääääääääää '. The binary representation used here is the same method described
in
Section 6.3.
You can also use the wildcard character to set the crosspoints of a row or column individually. For example,
'F04MGAIN1,*,ääääääääzzzzxxxxxx' sets the crosspoints of input 1 to 0 dB for outputs 1-8, -10 dB for
outputs A-D, and -12 dB for outputs R1, R2, and W-Z. In this case, the EF2280 will respond with a status
message of 'F04MGAINSG,*,ääääääääzzzzxxxxxx'.
Queries using the '?' character work in the usual manner. For example, 'F04MGAIN3,A,? ' might return
'F04MGAIN3,A,-6 ', while 'F04MGAIN2,*,? ' might return 'F04MGAIN2,*,ääääääääääääääääää '.
Boolean matrix commands work as you would expect. They use the characters '0', '1', and '2' as described in
Section 6.1. Here are some examples.
● 'F04MMUTE2,3,1 ' mutes crosspoint (2, 3) of the main matrix. In other words, the signal at input 2 will
not be heard on output 3 A status message will be generated of the form 'F04MMUTE2,3,1 '.
● 'F04MMUTEA,*,111111110000000000' sets the mutes for input A of the main matrix. The signal path
from input A to outputs 1-8 is muted, while the signal path from input A to outputs A-D, R1, R2, and W-Z
is unmuted. The EF2280 will respond with a status message of 'F04MMUTEA,*,111111110000000000'.
● 'F04MMUTEA,*,2' toggles the mutes for input A of the main matrix. If this command follows after the
command in the above example, the EF2280 will respond with a status message of
'F04MMUTEA,*,000000001111111111'.
● 'F04MMUTEA,*,?' queries the status of the mutes for input A of the main matrix. If this command follows
after the commands in the above examples, the EF2280 will respond with a status message of
'F04MMUTEA,*,000000001111111111'.
It should be noted that in EF2280 firmware versions earlier than 2.x, the P-bus was not implemented. Thus,
there were two less inputs to the main matrix (PM0 and PM1) and one less output to the main matrix (P). This
means that matrix commands for earlier versions of the firmware had different requirements for the number of
characters in a row or column of the main matrix. To preserve backward compatibility and ease migration to the
new firmware, the 2.x firmware supports both formats of matrix commands. If the P-bus entries are left out of a
matrix command, the command will still execute correctly and the P-bus crosspoints will not be changed.
6.5. Miscellaneous Commands
Miscellaneous commands are those that don't fall under any of the other categories. See the description of a
given command for specific details on how it operates.
7. Command List
The following table is a list of the commands recognized by the EF2280 Detailed descriptions of each command
are given in the next section.
The Storage column contains one of the following values indicating when and where the parameter is stored.
● "Global"
● "Preset"
