Accessing the I/O Board
The I/O board is accessible when the 5200A front panel is removed. The letters
on the metal plate, which is attached to the lower board assembly, identify ground
wire termination locations and pluggable terminal strip locations on the I/O board.
Letters on the metal plate correspond to the wiring diagram located on the inside of
the front panel - figure 3.14. A ribbon cable connects the display board (mounted
in the front panel) to the I/O board. When the 5200A front panel is removed, a
lanyard protects against stress on the ribbon cable. See Open Front Panel to Access
I/O Board - page 39.
