To detect if an input level to the Audio Detector exceeds the threshold

- The DME will return the one-line character string "GMT ERR" if it fails.

E.g.) ACK when it succeeds in obtaining a meter of an index of 5 (four channels) (The numbers below are examples)

GMT OK

MTR 0 5 CUR -13801 -2000 -3000 -13801 HOLD -13801 -1500 -2800 -13801

(The character string stands for "MeTeR".)

ACK when it succeeds in obtaining a meter of an index of 5 (eight channels) (The numbers below are examples)

GMT OK

MTR 0 5 CUR -1800 -2300 -200 1 -300 0 -13801 -13801 HOLD -1500 -2000 -0 1 -200 1 -13801 -13801

ACK when it fails in obtaining a meter of an index of 5 (four channels)

GMT ERR

19) GCMT: Used to set cyclical obtaining of a level meter.

Option The DME's ACKs when it succeeds The DME's ACKs when it fails

GCMT 0 [index] [a meter value]　 GCMT OK GCMT ERR

MTR 0 [index] CUR [CH1] … HOLD [CH1] …

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 DME.

The level meter value will be sent until it is cancelled with a QCMT command described later. Up to 100 meters can be registered.

- The first option will always take "0." It is reserved for future extensions to the command.

- The same as [index] GMT.

- The same as [a meter number] GMT.

- One or more spaces are needed between the command and the option, and between the options.

E.g.) To register cyclical obtaining of a level meter for a specific channel (index 1, parameter number 3)

GCMT 0 1 3

E.g.) To register cyclical obtaining of a level meter for every channel (index 1, parameter number 0)

GCMT 0 1 0

- The DME will return two lines of character strings if it succeeds.

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 DME will return a one-line character string of "GCMT ERR" if it fails.

E.g.) An example of the DME transmit and receive data when assigning a specific channel (index: 1, meter number: 3)

GCMT 0 1 3

MTR 0 1 CUR -1800 HOLD 0

： (Remote Controller will receive meter data cyclically from the DME.

)

MTR 0 1 CUR -1700 HOLD 0

E.g.) An example of transmit and receive data when assigning all channels (index 1, meter number: 0)

GCMT 0 1 0

MTR 0 1 CUR -1800 -2300 -200 1 -300 0 -13801 -13801 HOLD 0 0 0 0 0 10

Level

If an input level to the Audio Detector exceeds the threshold, the meter level becomes "Over," which

is different from conventional meter operation. Obtaining the character string "MTR 0 1 0 CUR 1

HOLD 1" indicates that the input level exceeds the threshold.
