Connecting External Devices IEEE1394 Connection "Backup recording" can be performed, which allows the same image recorded to the SDHC card on the camera recorder to be recorded to the external device connected to the IEEE1394 terminal. (A Page 122) Backup Recording When the camera recorder is set to Camera mode, images shot using it can be stream output from the IEEE1394 terminal. According to the recording operation on the camera recorder, recording to the camera recorder and external device may be performed synchronously or separately. 1 Connect the camera recorder to the backup device. Connect the camera recorder to the backup device using an IEEE1394 cable, using the camera recorder as the master device. Camera recorder (Master Device) [IEEE1394] Terminal [IEEE1394] Terminal Note : ● When connecting the camera recorder to an external device using an IEEE1394 cable, make sure to observe the following. Improper connection may cause the circuit of the connected unit to malfunction. ● Turn off the power of the camera recorder and connected devices before connecting the IEEE1394 cable. ● Do not connect the cable in an environment where static electricity occurs or is likely to occur. ● Make sure that each camera recorder is connected to only one external device at any one time. ● When the video format input from the [IEEE1394] terminal is different from the video format of the camera recorder, a AVIDEO FORMAT INCORRECTB message is displayed. Set according to the video format entered for [System Definition], [Camera Resolution], and [Frame & Bit Rate] in the [Record Format] menu. (A Page 75) VIDEO FORMAT INCORRECT ● If the [INT/EXT] IEEE1394 interface terminal switch is set at AEXTB and the AHQB mode is selected in [Frame & Bit Rate], signals will not be output from the [IEEE1394] terminal.

Perform setting in the [Record Format] menu. Select a video format in [System Definition]. (A Page 75) [HD (MPEG2)] : Performs backup in the HDV format. [SD (DV)] : Performs backup in the DV format. Note : ● To back up in the HDV format, be sure to select SP mode for the [Frame & Bit Rate] setting. 4 Perform the following settings on the camera recorder (master device). A Set the [INT/EXT] IEEE1394 interface terminal switch to AEXTB. B Switch to Camera mode. C Specify how recording to the camera recorder and external device is to be performed with the recording operation on the camera recorder using [1394 Rec Trigger] in the [Others] menu. (A Page 94) 122
