OPERATION When a system event occurs, the Operating Unit sends a print message to the
FCA2018-U1 via UFP. The FCA2018-U1 is responsible for printing the message. The
FCA2018-U1 contains a buffer to ensure that events that occur at a rate faster than the
PAL-1 can print them are not lost.
The FCA2018-U1 continu-
ously monitors the
connection to the PAL-1
checking for any errors
that would inhibit printing.
Any errors that are
detected are communi-
cated to the Operating
Unit via UFP for annuncia-
tion. Restoration to the
normal condition is also
detected and communi-
cated to the Operating
Unit. Print messages that
arrive at the FCA2018-U1
during a printer fault are
stored in the buffer.
Controls and Indicators The UFP side panel of the
FCA2018-U1 contains one
reset switch, three LEDs,
one termination switch and
one UFP address switch as
shown in Figure 2.
A reset switch is located
on the top of the panel.
Pushing the reset switch
re-initializes the FCA2018-
U1 operation.
POWER (Green) Normally ON. When illuminated, indi-
cates that power for the FCA2018-U1 is
applied to the module.
CPU FAIL (Yellow) Normally OFF. When illuminated, indi-
cates that the module microprocessor
has failed.
UFP FAIL (Yellow) Normally OFF. When illuminated, indi-
cates that the UFP communication with
the FCA2018-U1 has terminated.
A three-position switch located directly beneath the LEDs on the UFP side of the
FCA2018-U1 is used to set the UFP network address of the FCA2018-U1.
