the FR6802
+
frame genlock input. This is determined by the
position of jumper J1 on the ENC6800
+
or ENS6800
+
module as
shown in Figure 2-3 .
• Genlock 2 (labeled 625 on the rear module): If this setting is
chosen, the genlock source will be taken from the Genlock 2 input
of the rear module and is independent of the jumper J1 setting.
• Auto : Varies between Genlock 1/Frame and Genlock 2 genlock.
This is used if the card is expected to auto-switch between an NTSC
or PAL-M reference and a PAL-B reference based on the video
input. In this case one reference input would be applied to the
Genlock 2 input, and the other reference input would be applied to
either Genlock 1 or Frame . Then when the input signal changes
between SD 525 and SD 625, the genlock will automatically switch
to the appropriate genlock source. Remember that jumper
J1
determines whether Genlock 1 or Frame is the source of the first
genlock input (see Figure 2-3 ).
When the genlock source input is valid, the Genlock LED will turn
green. If you are using an ENS6800
+
and the Genlock LED never turns
green, ensure that the Frame Sync Mode parameter is not set to Delay.
Setting Jumper P1 for Reclocking and IO_DELAY Output
Follow this procedure to set the P1 jumper to select Reclocked SDI or
IO_DELAY output to a BNC output connector on the back module:
1. Locate jumper
P1 on the module. See Figure 2-1 on page 12 .
2. Place a jumper on pins 2 and 3 to set the module for SDI RCLK , or
place a jumper on pins 1 and 2 and another jumper on pins 3 and 4
to set the module to output
IO_DELAY .

IO_Delay Output
Note
Even though the rear module is
labeled
525 for Genlock 1 and
625 for Genlock 2 either type of
standard can be applied to either
of the inputs. They are not 525
or 625 dependent. However the
same type of genlock format
(NTSC or PAL-B) should never
be applied to both genlock input
sources at the same time.
Note
The ENC6800
+
does not
have IO_DELAY.
