Accessing the I/O Board
The I/O board is accessible when the 5200A front panel is removed. The letters on
the metal plate attached to the I/O board identify pluggable terminal strips 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.
