Configuring a VIM
CAUTION: A VIM circuit board can plug
into any unused slot that has a rear VIM
BNC panel. However, to install the system
efficiently and to facilitate troubleshooting,
ALWAYS install VIMs in series beginning
at the right-most slot as viewed from the
rear of the bay.
CAUTION: The video input selection is
independent of the video output selection.
However, both inputs and outputs must be
selected correctly based on the slot the
VIM is plugged in to.
Set the VIM to identify the inputs and outputs it is to
respond to. The VIM has two 8-position switches: S1
and S3. Referring to Figure 13, Table 4 and Table 5:
1. Remove the VIM from the bay.
2. Set switch S1 positions 1 and 2 to select one of
16 monitor levels (each containing 16 monitors).
The monitor level is determined by the bay's
hierarchy within the matrix system.
3. Set switch S3 positions 1 and 2 for the
appropriate range of inputs in increments of 1024
(positions 3 through 8 are not used).
4. Set switch S1 positions 3 through 8 to narrow the
input selection to the VIM's 16 inputs. The 16
inputs selected is determined by the VIM's
location in the bay and the bay's hierarchy within
the matrix system.
5. Plug the module into the right-most open VIM slot.
6. Repeat this procedure for the next VIM, if
required.
