Troubleshooting (FAQ)
Q:
Is it possible to control TXn/ACD1 from multiple external control devices?
A:
No, only one controlling device is allowed.
Q:
Is it okay to leave the port open until all communications have completed?
(Must the port be opened and closed each time a command is sent?)
A:
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:
Can the TXn/ACD1 receive the parameter setting command SPR in the middle of scene recall processing?
A:
Q:
If the response speed of the TXn/ACD1 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.
Only the GPI output from a port specified by the SGO command is controlled.
No, the command is disabled during recall. All the commands transmitted to the TXn/ACD1 in the middle of scene recall processing
will be ignored. When scene recalls are complete, the TXn/ACD1 will restart receiving the SPR command.
The parameter setting command can be transmitted after checking the SCN command notified from the TXn/ACD1 when scene
recalls are complete.
When a large number of commands are transmitted to the TXn/ACD1 in a short time, processing time may be longer because data is
accumulated in the receive buffer.
Leaving the port open is okay. There is no need to open and close the port each time a command is sent but the port should not be
left open for long periods of time.
・If you want to display a meter in the Meter component, you can ensure a faster response speed by assigning the multiple-channel
Meter component, rather than by assigning multiple one-channel Meter components.
In this case, make sure that the transmission interval between the commands for the remote controller is long enough for optimum
processing.
・If the cyclical period for automatically obtaining a meter is too short, the response speed will be slow due to the accumulation of 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 command
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.
