There can be up to three
magnetic stripe readers
attached to the MSR control
card. Each MSR is attached to
a partition in storage which is
the same one used by its
associated keyboard. These
partitions/stations are
numbered 0, 1, and 2.
The signal lines to and from
the MSR control card are common
to all three stations. The
only exceptions are the
'Photocell' and 'Raw Data'
inputs coming into plugs on the
side of the card from the
reader stations. Each of these
plugs works with a specific
par tit ion-
0
n 1 y .
- To check each station for
correct operation load
'MSRTEST' from the diagnostic
diskette at the associated
keyboard station and pass the
test MSR card (P/N 8331402)
through the reader (MIM 751).
The correct message which
should appear on the screen is:
BBB0123456789BACDE0123456789.
- All three stations need not be
used on any given system.
