1) From menu group 7, move the cursor to 9pinLocPr and press SELECT:

9 p i n L o c a t e P r e r o l l

0 0 m i n 0 0 s e c

2)Use the numeric keypad to enter a time in minutes and seconds between 00:00 and

59:59.

3)Press and hold down the SHIFT key and press the ENTER/LOAD key to transfer the value to the display screen.

Alternatively, you can use the UP and DOWN keys to alter the values of the minutes and seconds fields.

9.3.3 Serial unit timing source

The RS-422 device can be set to accept its timing signals from either external timecode, or from the Timer 1 internal time source (the video CTL sub- code track).

1)From menu group 7, move the cursor to 9pinTimMod (9-pin time mode) and press

SELECT:

9 p i n T i m e M o d e

T i m e c o d e

2)Use the UP and DOWN keys to select either Timecode or the Timer 1 timing source (subcode timing).

If the timecode option is selected and the VTR does not include a timecode reader, or the tape has not been striped with timecode, the RC-898 tape counter will show all hyphens: --:--:--.--.

9.3.4 Split mode on the serial unit

There are two ways of operating the E2 unit with the RC-898 transport controls. Firstly, all transport controls, including the record (REC key and the REC FUNCTION keys 41 through 46) can be used to control the VTR acting as the E2 unit con- nected to the RS-422 port. This is referred to as “normal” mode.

In normal mode, the following RC-898 keys per- form these P2 functions:

ALL SAFE

Standby

ALL INPUT

FULL EE

AUTO MON

SEL EE

PRRL

Preroll

RHSL

AUTO PUNCH

AUTO EDIT

However, in a video post-production situation, it is quite likely that you will need to control the trans- port of a VTR, which acts as a timecode master for the DTRS slaves. These DTRS slaves will be used for recording, but the VTR will not (other- wise the worktape will be erased!). The RC-898 therefore provides you with a “split mode” in which all transport keys except the RECORD key and the REC FUNCTION keys control the VTR, and the recording keys control the DTRS units.

In this way, all recording operations, including auto-punch operations, can be carried out on the DTRS units without the risk of accidentally eras- ing the VTR tape.

However, there is one function where operation is slightly different, and this is “on-the-fly” punch- ing. Usually, when DTRS tracks have been armed, and the tape is being played, pressing RECORD will drop the tracks into record mode, and press- ing PLAY will drop them out into play mode. In split mode, this is not possible, since the PLAY key controls the VTR.

To punch in and out of armed tracks on the fly in split mode only, press RECORD to drop in, and RECORD to drop out again.

To change between normal and split mode:

1)From menu gropup 7, move the cursor to 9pinCtlMd (9-pin control mode) and press

SELECT:

9 p i n C o n t r o l M o d e

S p l i t

2) Use the UP and DOWN keys to select between Split and Normal.

9.3.5 Controlling recording operations on the serial unit

If split mode has been selected (see 9.3.4, “Split mode on the serial unit” above), the following
