21) QCMT: Used to cancel cyclical obtaining of a level meter.

QCMT [AMP ID][Access ID][Meter #] QCMT OK QCMT ERR
The command name stands for "Quit Cyclic Meter".
It will be used to cancel cyclic transmission of a level meter registered in the TXn/ACD1 with the GCMT command.
- If sending to a TXn, [AMP ID] is always 0. If sending to an ACD1, [AMP ID] is the AMP ID (0 to 39) assigned to the amp to be controlled.
- [Access ID] identifies the level meter.
- "0" should be always assigned to [Meter #].
- One or more spaces are needed between the command and the option, and between the options.
E.g.) To discard registration of an obtained meter cycle:
QCMT 0 1234 0
-The TXn/ACD1 will return a one-line character string of "QCMT OK" if successful.
-The TXn/ACD1 will return a one-line character string of "QCMT ERR" if unsuccessful.
E.g.) ACK if successful in discarding meter number registration.
QCMT OK
ACK if unsuccessful in discarding meter number registration.
QCMT ERR
22) SMC: Used to set the cyclical period for automatically obtaining all level meters.

SMC [AMP ID] [Cycle] SMC OK SMC ERR
The command name stands for "Set Meter Cycle".
This command will enable the user to set a cycle in ms units for sending all level meters set to be obtained cyclically.
The TXn/ACD1 will send level meters at 100 msec intervals if the TXn/ACD1 have not received this command.
- The first option will always take "0." It is reserved for future extensions to the command.
- The meter transmission interval from the TXn/ACD1 should be assigned to [Cycle] in ms units.
- One or more spaces are needed between the command and the option, and between the options.
E.g.) To change the meter transmission interval from the TXn/ACD1 to 200msec:
SMC 0 200
- The TXn/ACD1 will return a one-line character string of "SMC OK" if successful.
- The TXn/ACD1 will return a one-line character string of "SMC ERR" if unsuccessful.
E.g.) ACK if successful in changing the meter transmission interval:
SMC OK
ACK if unsuccessful in changing the meter transmission interval:
SMC ERR
Guide for setting the cycl
e
An appropriate cycle needs to be set in accordance with the number of the level meters to be obtained cyclically.
Follow the table below to find an appropriate cycle.
A table of the number of the level meters and the required cycle
TXn ACD1
AMP ID: 0-31 (DATA PORT connector
)
250ms or longer
AMP ID: 32-39 (MONITOR/REMOTE connectors)
Please determine and set an approximate cycle based on the table above and the estimation of the cycle below.
Estimation of the cycle:
Example 1: To obtain 40 ch of level meters from the TXn,
The table above shows the required cycle for obtaining the level meters is 80 ms.
Example 2: To obtain the total 10 ch of level meters from AMP ID: 32-39 of the ACD1,
The table above shows the required cycle for obtaining the level meters is 50 ms.
