8 Operation

This section describes how to operate the CCS 1000 D Digital Discussion System.

8.1 Recording and playing back discussion

Figure 8.1: CCSD-CURD

The built-in recorder is used to record discussions in the MP3 format. Recordings are saved to the internal memory or an appropriate USB memory stick, when connected. Refer to the information on USB memory stick in Additional components, page 14.

During recording, the full capacity of the USB memory stick may not be used because:

- Multi-device USB memory sticks are supported, but only one internal memory device on the USB memory stick is used.

- USB devices with multiple partitions are supported, but only the first partition is used.

The memory size of the USB stick and recording settings determine the total recording time.

The internal memory can save up to 8 hours of discussion at the lowest bit rate. For an overview of the possible recording times compared to the bit rate, see Technical data, page 63.

The appropriate memory (internal/USB) and LED indicator are automatically selected and deselected when the USB memory stick is inserted and removed from the USB connector at the front of the Control Unit.

Recording options

When recording is started, the MP3 recorder automatically creates an MP3 file, using the current date and time as the file name.

Recordings saved on the USB memory stick have the filename: 'USB:yyyymmdd-hhmmss-Floor.mp3'.

- If the recording setting source is set to Floor and output x (x = 3, 4, 5 or 6), a second recording file is stored with the same date-time stamp: 'USB:yyyymmdd-hhmmss-Outputx.mp3'.

- If the recording is made on the internal memory, the file name starts with 'IM' instead of 'USB'.

By default, recorded files have a maximum duration of 60 minutes. After 60 minutes, the file is automatically closed, and a new file is created. This process is repeated as long as recording is active or until the internal memory or USB stick is full.

If you want discussion to be recorded to one continuous file, a 'no-file-split', should be created in the internal flash of the Control Unit. To do this:

1. Connect a laptop or PC to the Control Unit, by using the micro USB connector at the rear of the Control Unit..

2. Under the detected drive for the Control Unit, create a txt file called 'no-file-split'.

3. Remove the file extension ".txt."

To reset recorded files to a maximum duration of 60 minutes, delete the 'no-file-split' file.

Making a recording

Notice!

It is recommended to use a USB memory stick for external recording. If required, an external recorder can be connected to RCA 'Audio Out (2)' of the Control Unit.

Notice!

Make a back-up of the files on your USB memory stick before inserting it into the control unit.

1. Connect a USB memory stick to the USB connector (13) at the front of the Control Unit. The USB recording LED indicator (10) will light up green to indicate that the stick has been detected and recording can begin.

2. Press the 'start/pause' recording button (11) to start a recording session. The LED indicator will turn red to indicate that recording is active.

- To pause recording, press the 'start/pause' recording button again. The LED indicator will flash red to indicate that recording is temporarily stopped.

- To resume recording, press the 'start/pause' recording button again. The LED indicator will turn red to indicate that recording is active.

- To stop recording press the ‘stop recording’ button (12). The LED indicator will turn green to indicate that the recording session is complete.

Recording will automatically stop when:

- Internal recording is taking place and a USB memory stick is inserted into the USB connector (13) at the front of the Control Unit.

- External recording is taking place and the USB memory stick is removed from the Control Unit. Only remove the USB memory stick when the green recording LED is on.

- The internal memory is full when recording internally.

- The USB memory stick is full when recording on USB memory stick.

Playing back a recording

To playback a recording either:

- Connect a tablet, laptop, or PC to the Control Unit, via the Ethernet connection, and use the web browser interface to select which recording has to be played back. See Web browser interface, page 38.

- Remove the USB memory stick, and transfer the MP3 file(s) to a PC.

- Download the MP3 file(s) from the internal memory of the Control Unit to a PC, by using the micro USB connector at the rear of the Control Unit.

Notice!

Recordings cannot take place when the Control Unit is connected to a PC with the micro USB connector.
