Troubleshooting (FAQ)
Q:
A:
No, it is not possible. Be sure to set the baud rate of the remote controller to 38400bps.
For more information, see the section "1.2 Remote Controller Settings."
Q:
What should be used as a line feed code of a command?
A:
LF (0x0A) can be used as a line feed code ("$0A" for AMX, "\x0A" for Crestron).
For more information, see the section "3.1 Basic Command Specifications."
Q:
Up to how many parameters can be controlled with the communication protocol?
A:
The maximum number of specifically defined controllable parameters is 256, as set in the Remote Control Setup List of DME Designer.
Other controls such as scene recall are in addition to this.
Q:
How can I control more than 256 types of parameters?
A:
You can use MIDI and/or GPI signals in addition to the remote control protocol.
Q:
Can the MIDI parameter change and/or control change be transmitted via Ethernet?
A:
No, the MIDI parameter change and/or control change cannot be transmitted via Ethernet.
The SPR command can be used to change parameters. The RSC command can be used to recall a scene.
Q:
Can the DME receive the parameter setting command SPR in the middle of scene recall processing?
A:
Q:
Is there any difference in response time for parameter changing, depending on the type of component?
A:
Q:
If the response speed of the DME to a command is slow, what are the possible causes and solutions?
A:
Q:
If the response speed of the meter is slow, what are the possible causes and solutions?
A:
The response speed of the meter will be slow when the number of meters displayed on the screen increases.
In this case, try the following solutions.
For more information on commands see GMT and GCMT in the section "3.3.3 Command to Obtain Level Meter."
Q:
If a parameter is assigned to "GPI OUT" and the port is controlled by the SGO command, does the parameter link?
A:
No, the parameter does not link.

Q:
Can the input level to the Audio Detector be detected if it exceeds the threshold?
A:
Yes it can.
For more information on detecting the level see the section "3.3.3 Command to Obtain Level Meter."
In this case, make sure that the transmission interval between the commands for the remote controller is long enough for optimum
processing.
Is it possible to communicate with the DME at a baud rate other than 38400bps for serial communication via the REMOTE
connector?
The parameter setting command can be transmitted after checking the SCN command notified from the DME when scene recalls
are complete.
A component (such as Matrix Mixer 64x64) with various parameters may require longer time for parameter change than a
component with a small number of parameters.
When a large number of commands are transmitted to the DME in a short time, processing time may be longer because data is
accumulated in the receive buffer.
No, the command is disabled during recall. All the commands transmitted to the DME in the middle of scene recall processing will be
ignored. When scene recalls are complete, the DME will restart receiving the SPR command.
・If the cyclical period for automatically obtaining a meter is too short, the response speed will be slow due to the accumulation o
f
data. Try to set a cycle as long as possible using the SMC command.
・The response speed will be faster by using the GCMT command that can obtain data cyclically than by using the GMT comman
d
that obtains data each time, because the volume of communication decreases.
・If you want to display multiple meters in the same component, you can ensure a faster response speed by assigning a value of "0
"
to a meter number to obtain data all at once, rather than by assigning a meter number to obtain data individually.
・If you want to display a meter in the Meter component, you can ensure a faster response speed by assigning the multiple-channe
l
Meter component, rather than by assigning multiple one-channel Meter components.
