The interface follows the recommendations
set up
in EIA
RS
232-C and
C.C.I.T.T. V-24.
CURRENT
LOOP transmission, 20mA or 60mA, is
also incorporated. The interface permits se·
rial data to be received and transmitted to
on
auxiliary device or
to
the punch. The
interface also permits parallel data to be
received from the reader and transmitted
to
a
line device or
to
the punch or to an
aux-
iliary device. The desired system is inten•
ded to be set up ot the time of installa•
~
tion but may easily be changed simply by
using jumpers and changing the set-up of
operational mode switches.

2.3 CONNECTORS
Two
receptacles,
LINE (X3)
and
AUX (X2)
are
used. Mating connector shells should only be
of
type
AMP
206478-3 in order
to
ovoid short
circuit to the interface. See Fig. 5.
X2 and X3 have the same pin designation.
Where the signal straight'through is the
same point the pin number is encircled.

2.4 BAUD
RATES
The system uses a frequency 16 times the
baud rate. There ore two separate selectors
for
the BAUD
RATE
operated
by
jumpers. One
for the READER, PS3 and one for the PUNCH,
PS
4.
In
"ON LINE" mode they work indepen-
dently. In "OFF LINE"
mode the BAUD RATE is
controlled
by
the PUNCH selector, PS 4. The
following BAUD RATES ore available:
READER:
4800-2400-1200-600~300-150-110-
-75-50 bps.
PUNCH:
600-300-150-110-75-50 bps.
