Panasonic AJ-LT85P manual Turning on the REC Same function, REC Through function

TIME CODES (TC) and USER BITS (UB)

REC SAME function

This function is used to record the same time code and user bit values on VTR1 and VTR2 when both machines are in the record (NORMAL REC) mode. The values from the time code generator (TCG) and user bit generator (UBG) are recorded on both VTR1 and VTR2.

Turning on the REC SAME function

!Set the VTR to the stop mode. @ Switch to the set-up menu.

# Set VTR2 item No. 507 to VTR1TC (0004).

$ Set the OPERATION MODE switch on the front keyboard to SEP.

<Note>

The REC SAME function causes the time codes and user bits recorded on VTR1 and VTR2 to match only while both are in the record (NORMAL REC) mode. Therefore, if VTR1 is not in the record (NORMAL REC) mode, the time codes recorded on the VTR2 may lack continuity. The same user bit values continue to be recorded. Also, VTR2 always uses the TCG and UBG of VTR1 for regeneration, regardless of the setting for item No. 507 (TC MODE).

REC THROUGH function

When a multiple number of VTRs have been connected in a daisy-chain configuration using TC IN/OUT (LTC), this function enables recording by using TC IN/OUT (LTC) so that the master VTR’s time code generator value will serve as the reference TC for all the VTRs.

<Note>

In the case of the master VTR, set the TC OUT output timing to TCOUT1 irrespective of the TC MODE.

In the case of the slave VTRs, set the TC OUT output timing to TCOUT1 when E-LTC is selected as the TC MODE.

<Note>

The item No.502 (VITC BLANK) setting of VTR1 is valid only during playback.

In any other mode, the data which is input from an external source will be output.

TC OUT (LTC) output specifications

Playback system	: The data on the tape is output at the TCOUT2 timing.
All other systems : Refer to the table below.
