Appendix E – Vertical Interval Sync (VIS)

Modula Instruction Manual
Configuration Requirements
If the original configuration file has not been modified, a CD has been included with a new
configuration file, which
must
be uploaded to the system with XNConnect for the VIS board to
work. The new file will automatically enable the VIS board for the system.
If the original configuration file has been modified and you do not want to replace it, use
XNConnect to enable the VIS board (see page 183).
Before starting:
Turn off and unplug the enclosure. For multiple-enclosure systems, turn power off and unplug
all enclosures that will have a VIS board added or enabled.
If necessary – If cables from adjoining boards obstruct access, label and disconnect them as
necessary.
Termination Load Jumper
VIS boards are shipped with the termination load jumper (J1) set to the “off” position (covering jumper pin
number 1) for high impedance. If the house sync generator does not have a termination load of 75 ohms,
the J1 jumper
must
be set to the “on” position (covering both jumper pins) to internally set a 75 ohm load.
FIG. 114 shows the jumper location on Modula VIS boards.
To set the termination load jumper:
1.
If the VIS board is already installed, remove it from the enclosure (see Steps 1 and 2 of the installation
procedure on page 179).
2.
Set the J1 jumper according to FIG. 114.
3.
Replace (install) the board (see Steps 3 through 6 on page 180).
