Specifications

- The TXn/ACD1 will return two lines of character strings if successful.
The first line will have a character string of "GMT OK."
The second line will have a character string of "MTR [index] CUR [CH1] [CH2] … HOLD [CH1] [CH2] … ".
The first character string can be ignored for the controller.
The same number of current meter levels as that of channels comes after CUR in the second line.
The same number of current meter hold levels as that of channels comes after HOLD in the second line.
The meter and hold level number ranges from -13801 to 1.
The following table shows the relationship between character strings and levels sent from the TXn/ACD1.
- The TXn/ACD1 will return a one-line character string of "GMT ERR" if unsuccessful.
E.g.) ACK when command to get meter values for meter access ID (1234) on channel 4 is successful
GMT OK
MTR 0 1234 CUR -13801 -2000 -3000 -13801 HOLD -13801 -1500 -2800 -13801
(The command name stands for "MeTeR".)
ACK when attempt to get meter values for meter access ID (1234) on channel 8 is successful
GMT OK
MTR 0 1234 CUR -1800 -2300 -200 1 -300 0 -13801 -13801 HOLD -1500 -2000 -0 1 -200 1 -13801 -13801
ACK when command to get meter values for meter access ID (1234) on channel 4 fails
GMT ERR

The command name stands for "Get Cyclic Meter".
CUR stands for "Current meter value".
HOLD stands for "Peak hold value".
Registering a meter number to be obtained using this command will send the level meter value cyclically from the TXn/ACD1.
The level meter value will be sent until it is cancelled with a QCMT command described later. Up to 100 meters can be registered.
- 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.
- The same as [Access ID] GMT.
- The same as [Meter #] GMT.
- One or more spaces are needed between the command and the option, and between the options.
E.g.) To register to cyclically (periodically) receive level meter values from specified channels (Meter access ID 12345, meter #3):
GCMT 0 1234 3
E.g.) To register to cyclically (periodically) receive level meter values from all channels (Meter access ID 12345, meter #0):
GCMT 0 1234 0
- The TXn/ACD1 will return two lines of character strings if successful.
The first line will have a character string of "GCMT OK."
The second line will have the same character string as ACK when obtaining a meter using GMT.
- The TXn/ACD1 will return a one-line character string of "GCMT ERR" if unsuccessful.
E.g.) Communication sequence with TXn, initiated by registering for periodic receipt of meter values for specified channel
(Meter access ID 1234, meter #5):
GCMT 0 1234 5
MTR 0 1234 CUR -1800 HOLD 0
： (Remote controller continues to periodically receive meter data from the TXn/ACD1.)
MTR 0 1234 CUR -1700 HOLD 0
E.g.) Communication sequence for periodic receipt of meter values from all channels (Meter access ID 1234, meter #0):
GCMT 0 1234 0
MTR 0 1234 CUR -1800 -2300 -200 1 -300 0 -13801 -13801 HOLD 0 0 0 0 0 10
