Upgrades and Repairs
You can perform the following upgrades and repairs to the scan converter:
• Installing the VSC 200/300 D1 Module (VSC 200/300 only; see below).
• Replacing the AC fuse (see page B-4).
• Installing a firmware update (see page B-5).
Before completing any of these procedures, follow the instructions in “Internal
access”, below.
Internal access
Upgrades and fuse replacement require access to the internal areas of the scan
converter. To access the internal areas, do the following:
1. Remove the power cable from the scan converter.
Do not open the cover of the scan converter without unplugging the power cord.
2. If the scan converter is rack mounted, remove the input and output cables
from it, remove the unit from the rack, and remove the rack mount brackets
(see figure 27). If the scan converter is not rack mounted, you do not need to
remove the input and output cables.
Figure 27 — Removing the cover
3. Remove 14 screws from the sides and top of the cover (figure 27).
4. Remove the cover by slightly lifting each side alternately until the cover is
