2) Use the UP and DOWN keys to choose between

on and off.

When this parameter is set to on, the REC FUNCTION keys which usually control tracks 41 through 48 (DTRS 6) will now control the E2 device logical analog and digital tracks (no matter what the tracks actually are) as marked.

The following chart explains the relationship between the serial unit, the split/normal mode, and this function:

9.4Other DTRS control functions

98The following functions described DTRS fea- tures which relate to control, but are not timecode- related. The RC-898 can only perform these func- tions on DA-98 units. Some of these functions are available on DA-88 units, but they cannot be con- trolled from the RC-898.

9.4.1Choosing a control protocol

98The DA-98 can be controlled from a variety of external sources as well as the RC-898. These sources are: P2 protocol (9 pin), MIDI Machine Control, and a bus protocol carried over the RS- 422 cable and produced by, for example, the TAS- CAM ES-61 editing controller. See section 11.0.1 of the DA-98 manual for further details relating to this function.

1)From menu group 3, move the cursor to Ctrl Prt (control protocol) and press SELECT:

C o n t r o l P r o t o c o l

M a c h i n e 1

9 P i n

2) Use the UP and DOWN keys to select between 9Pin, MIDI, Bus and off.

Even when a control protocol is selected, the RC- 898 and DTRS sync protocol can still be used to address and control the DA-98.

9.4.2 Track mapping functions

98When the track arming and recording of a DA-98 unit is controlled by an external controller, you can specify which tracks on the DA-98 corre- spond to the tracks controlled by the controller (for arming and recording purposes). The standard video controller protocol (P2 protocol) allows for control of up to eight digital and four analog audio tracks. This function allows you to map DA-98 tracks to the “logical” tracks.

This mapping of DA-98 tracks to controller tracks does not imply any correspondence between the user interface of the controller and the DA-98 tracks. It refers, rather, to the relationship between the command signals transmitted by the controller and the DA-98 tracks.

Note that while there are no user-settable track mappings, the pre-set mappings are designed to cover every set of circumstances.
