2 environment
------------------
the ptr/p (v 28 L/L) shall operate within the specified
limits under environmental conditions as specified
below. the v11/v28 l/l-adaptor shall be designed to
accomodate this operating environment requirement.
2.1 ambient temperature range: 0 to 40 deg. c.

and with normal scheduled preventive maintenance in
the following air environment:
a) air cleanness
-------------
particle size max allowable number
(microns) (praticles/cubicmeter)
--------------------------------------------------------
greater than 5 4 x (10 exp 5)
greater than 1.5 4 x (10 exp 6)
greater than 1 4 x (10 exp 7)
b) fumes
-----
sulphur dioxide max. 14 ppm.
3 power input…01…----------------
the ptr/p 8v28 L/L) shall be capable of satisfying
the specified performance requirement, when operated
with the power input specified below. the v11/v28 L/L-adaptor
shall be designed to accomodate this requirement.
3.1 voltage
-------
the equipment shall be capable or operating with a
220 v ac. single phase as well as a 240 v ac single
phase power supply, both with a tolerance of + 10%/-15%.
3.2 frequency
---------
nominal value: 50 hz
tolerances: +5/-5 hz
3.3 harmonic distortion
-------------------
max. 5%.
3.4 transients
----------
non-repetitive impulsive interference with a magnitude
not to exceed 500 volts, pulse rise and fall times
not faster than 10 microseconds and a total duration
of maximum 1 millisecond. the available impulse energy
at the equipment power inlet shall not exceed 5 j.
3.5 safety
------
where a voltage of more than 50 volts is exposed during
the maintenance activities, a suitable warning sign
shall be provided on the equipment.
3.6 grounding
---------
the grounding system shall be arranged so that there
are three separate and isolated ground circuits, namely:
a) ac power neutral
b) equipment frame ground
c) signalling and control ground
the ac power neutral shall provide a return for the
primary current, so that the equipment frame ground
is used only to establish a safety ground.
4 signal interface…01…--------------------
4.1 signal interface to ptr/p (v11)
-------------------------------
the electrical interface specification complies with
the ccitt v11 recommendation concerning the data and
control signal voltage polarities. all other charcteristics
are contrained by the mil-std-422 standard (low level)
digital interface specification.
the ptr/p (v11) operates as a dte device only and utilizes
the following circuits.
102 signal ground
103 transmit data (reader to host)
104 received data (host to punch)
105 request to send (reader to host)
106 ready for sending (host to reader)
108/2 data terminal ready (punch/reader to host)
(spe-
cial) punch (parity) error (punch to host)
transmission to and from the ptr/p (v11) is asynchronous,
600 baud, 11 bits/character, consisting of one start
bit, 8 data bits, one odd parity bit, and one stop
bit.
4.2 external signal interface
-------------------------
4.2.1 the external signal interface shall be provided
from the ptr/p (v28 L/L) by a connector, db 25
or equivalent.
the ptr/p (v28 l/l) is operated as dte.
4.2.2 the following ccitt, v24 circuits shall be provided
on the external signal.
102 signal ground 7
103 transmitted data 2
104 received data 3
note 105 request to send 4
note 106 clear to send 5
108/2 data terminal ready 20
note: strap option: it shall be possible between the
2 following alternative operations (iniital setting
for option b):
a) straight forward conversion as specified above.
b) circuit 105 is in this option not used in the external
interface.
106 on the signal interface to the ptr/p (v11)
shall be raised only if the following two conditions
are met:
1) 105 from ptr/p(v11)
is raised
2) 106 from external interface is raised.
4.2.3 in addition to signal and (pin 7) a separate signal
and pin shall be allocated for each driver circuit
as specified in the following scheme:

4.2.4 electrical specification
------------------------
a) the circuits for the external signal interface
shall be designed based on interrim report no.
3 dated may 1, 1981, prepared by arc for cr.
b) the circuits (except circuit 102) shall be designed
in accordance with mil-std-188c, sections 7.2.1
and 7.2.1.1-7.2.1.6.
b1) strap option 1: on receiver circuits, programming
of input impedance and threshold voltage for
the alternatives
1) mil-std-188c
2) v28
shall be provided by straps. the straps shall
not be field-replaceable.
strap option 2: a strap option for fail-safe
operation shall be provided for circuit 104
and 106.
4.3 transmission alarm interface
----------------------------
if a transmission error is detected by the ptr/p (v11)
upon receiving data for punching, this will be indicated
on the (special) interface circuit from the ptr/p (v11)
by a pulse.
a transmission alarm interface shall be provided on
the v11/V28 l/L adaptor in accordance with the following
requirements:
a) a set of relay contacts shall be provided. the
set shall be galvanic isolated.
b) a reset input/for push button operation) shall
be provided.
c) the relay shall be set, when a transmission error
pulse is received on the special circuit.
d) the relay shall be reset by
1) power up
2) activation of reset input
e) the transmission alarm interface is an option to
support e.g. an alarm indicator on the front panel
of the ptr/p (v28 L/L). this alarm will be accessible
only by opening the front door of the ptr/p (v28
l/l)
