Removing and Installing a VIS board
ESD Warning: To avoid ESD (Electrostatic Discharge) damage to sensitive components, make sure
you are properly grounded before touching any internal Modula materials. Use an ESD wristband
and cord with alligator clip attached to a good ground source.
Items Required
Modula VIS board(s)
Phillips #1 screwdriver
ESD wristband and cord with alligator clip
If applicable – Updated configuration file see the “Configuration Requirements” section
(page 178) to determine if required
Important: Be sure to install a VIS board in the expansion board slot next to the CPU. If a VIS board
is installed in an input or output board slot, signal routing is affected.
To remove and install a VIS board:
1.
Blank board plate – Remove top and bottom screws on the plate covering the empty expansion slot
and set plate aside (FIG. 115). Set screws aside for reuse.
Or
VIS board – Remove top and bottom screws on VIS board and carefully pull the VIS board straight
out of the board slot. Set screws aside for reuse.
2. Determine the setting of the termination load jumper J1 (FIG. 114 on page 178) on the VIS board
(new or previously installed).
If necessary, follow the steps on page 178 to set the jumper to the “on” position.
