Table DESCRIPTION
#
RS-232
There are three primary tables for VCRs using RS-232 protocol: Table 001 is for Sony
VCRs; Table 003 is for Panasonic VCRs; Table 004 is for JVC VCRs.
If the VCR has a step/linear choice for the jog or shuttle, select step.
Most RS-232 VCRs send time code or counter information over the Edit Control cable,
so set the TCSRC configuration parameter to INT. Set the TC parameter to the type of
time code sent by the VCR.
Some RS-232 VCRs have Real Time Counters only. If you have a VCR like this but
also have VITC or LTC striped on your tape, change the TCSRC to EXT and use table
021 (Sony), 006 (Panasonic), or 024 (JVC). The time code must be delivered to Edit
Suite via an audio (LTC) or video (VITC) cable attached to the Time Code IN port. In
this case, change TCSRC to EXT and change TC to VITC or LTC.
001
Sony: This is the primary table for Sony VCRs using RS-232 protocol. Table 005 is an
alternate table that was designed for the UVW-1400.
Turning the jog slowly advances/rewinds the video approximately 3 frames per
revolution. Increasing the rate causes the VCR to increase its jog speed up to a
maximum of Play speed.
Do not use this table if TCSRC=EXT. Use table 021 instead.
005 Sony: UVW-1400. The 1400 requires slightly different commands than the Table 001
commands to determine the VCR status and time code information. If table 001 does
not work for you, try this table.
If you select this table, watch Edit Suite's LCD while the VCR is playing to ensure that
the time code displays properly. If you see alpha characters or values that are out of
range, use table 001.
021 Sony: This table is normally used only if LTC or VITC time code will be sent to Edit
Suite via the Time Code In ports instead of from the Edit Control cable.
If table 021 is used, Edit Suite will control the search process (whereas with other 232
tables, the VCR controls the search). Because of this, you may need to adjust the
INPUT OFFSET parameter during the Fine Tuning process. See Chapter 7 for the
procedure to use. Also, change the FFD Advanced Parameter to 00:45.
011 Sony: Same as 001, except with a slightly different progression for the jog when
transitioning from slow jog to faster jog.
031 Sony: Same as 001, except each slow turn of the jog advances the video approximately
7 1/2 frames.
