NOTE

30 fps drop-frame is only supported by DA-98 units.

To change the timecode type used by the system, see 8.1.3, “Selecting a timecode type” .

[8]MACHINE number indicators (1

through 6, E1, E2)

This indicator shows the machine currently selected for control with the transport keys. , using the MACHINE key [31]. 1 through 6 refer to DTRS units. E1 and E2 refer to VTRs, etc. which may be connected to the RC-898. E1 is connected to the parallel port, and E2 to the 9-pin RS-422 port

[9]LOCK STATUS indicators

These indicators show the current lock status of the DTRS units as they chase to external synchro- nization sources. For units 2 through 6, the exter- nal synchronization master will typically be the first DTRS unit (1) in the chain.

There are four modes displayed by these indicators:

On

The slave unit is chasing the master and is

 

locked to it.

Fast flashing The slave unit is in chase mode, is in fast for- ward or rewind mode, and is not locked to the sync master.

Slow flshing The slave unit is in chase mode, stopped, and is not locked to the sync master.

Off

The unit is not in chase mode.

[10]OFFSET, PULL UP/DN, CONFIDENCE, DELAY, TC REC,

VARI indicators

These indicators are used to show the status of the appropriate mode on the currently-selected unit. The status is changed using the menus on the dis- play screen.

In addition, changing the values from the front panel of a DTRS unit connected to the RC-898 will change the status of this indicator, if the unit’s number corresponds to the current MACHINE number [8].

[11]LCD display screen

This 20-character x 4-line backlit display screen is used to show and set the different parameters available with the RC-898.

[12]Time Mode indicators

Only one of these indicators will be lit at any one time. They indicate the timecode reference (time-

code; TC, or absolute time; ABS) in use by the currently-selected DTRS unit and shown on the TAPE TIME indicator [13].

The REL indicator, when lit, shows that the cur- rent time, relative to a user-defined reference point, as explained in 6.3, “Setting a relative time reference”, is currently being displayed.

[13]TAPE TIME display

This display shows the current tape time on the currently-selected unit. The time reference is shown by the indicators at [12].

[14]MEMORY NO. display

This 2-digit counter shows the location memory which is currently in use (for storage, recall or location).

[15]LOCATE TIME/VALUE display

This display shows the time of the location mem- ory currently referenced by the MEMORY NO. indicator [14] or entered using the numeric keypad [16].

It is also used to show time values which are set as control parameters in various menu screens.

[16]Numeric keypad

The ten number keys are used for direct entry of values for location memories, etc., to select loca- tion memories for store, recall, etc., or for the entry of time values into LCD display menu parameters. The +/– key is used to change a posi- tive to a negative value, or vice versa.

The +/– key is also used with relative times, as explained in the relative time setting section in see 6.3, “Setting a relative time reference”.

[17]STR key

This key is used to start the process for storing a timecode value to a location memory. See 6.5.6, “Storing the location in a memory” for details.

[18]RCL key

This key is used to start the process for recalling a timecode value from a location memory. See 6.5.7, “Recalling a location memory” for full details.

[19]CANCEL key

This key is used to cancel the selection of a loca- tion memory with the number keys, before storing a time to it or recalling a time. It may also be used to cancel the setting of a numerical value if it has been wrongly entered.
