Installation
The VSM-6802 Video Signal Monitor can be installed into a 6800 series,
FR-7001 series, or FR-7000MB MIX BOX series frame. When the
VSM-6802 module is installed into an FR-7001 series or FR-7000MB
MIX BOX frame, a matching back box module is installed on the back of
the frame. When this module is installed into a 6800 series frame, only a
back panel overlay is required.

output composite analog video level. Terminate an output with 75
