LTl9A,B (C) Multi-Station Teletype Control and lnterface
1.1

Each LT19A added to a PDP-9 will acconunodc.te up to five
teletype control units (LT19B' S). These I,T19B control
units contain logical elements wnich are functionally
similar to those of the PDP-9 standard teletype control
Instructior~ and programming considerations are,therefore,
similar to those of the standard unit.

SAIZE ICsO DE I

The LT19A,B (C) system consists of an interface to
the processor (LTl9A) and up to five teletyp!
control units. (LT19B(C) ).

Optional Teletype Control with Standard ETA Level Converters
(Type LT19c)
T'he LT19C is a group of standard DEC logic modules Which,
when inserted into the appropriate locations of an LT19A,
constitute a single independent teletype control(exact1y
the same as the LT19B specified above)with standard EIA
level converters. Thus the LT19C may be directly connected
to input/output devices using standard EIJI logic levels, i.e.
dataphone.

One to five optional LT19B(C) tel~~ contrell
units may b~ added to each LT19A interface.
1.2

1.3

Each of the LTl9B (C) control units (up to fiv'e mav
be added) is optional - directly pluggable into tbe
LT19A interface.
The LT19A is packaged in two standard DEC #194319" logic mcunting racks. Up to five LTl9B (C)
control units may be plugged into the LTl9A logic
racks.
(10~" of mour.ting space is required).
When the LT19A,B (C) options are added to a PDP-S
system, these 1943 logic mounting racks rr.ust be
added to the system as shown in sect~on 4.0 and
all necessary cable connectors and power wiring
should then be added.

7.0

All connections from the LT19A,B (C) system to
the basic processor are made through the
standard PDP-9 10 Bus. No special cabling is
needed for the system. The optional teletype
units (or EIA standard level units) are
interfaced to LT19A,B (C) system as stated
in Section 7 (System C~~ponents). The single
control cable and its termi~ation module are
standard units which are delivered with the
optional input/output unit.

System Components
Basic system components consist of the LTl9A,B(C}
control logic (located in an optional bay) and up
to S teletype units or EIA level operated units
for each LTl9A control. The optional teletype
units or EIA units are located remotely from
The PDP-9 system. A single cont.rol cable interf;!lces
the remote unit to its control in the PDP-9 sy&t1em. This
control cable is terminated with a standard DEC '~070 cable
connector module which is inserted in its assign(~d location in ,
the LT19A mounting panels (see module utilization print
D-MU-LT19-A-3).

LTl9 D, E, F, H Multi-Station Teletype Control and Interface
Each LT19D added to a PDP-9 will accommodate up to five
teletype control units (LTl9E's). The:;e LTl9D control
units contain logical elements which are functionally
similar to those of the PDP-9 standard teletype control.
Instructions and programming considerations are, therefore,
similar t~ those of the standard unit.

Optional Teletype Control with Standard EIA Level Converters
(Type LTl9F)
The LTl9F is a group of standard DEC log it mod'lles ....hich,
when inserted into the appropriate locations of an LTl9D
constitute a single independent teletype control (exactly
the same as the LT19E specified above) with standard EIA
level converters. Thus the LTl9F may be directly connected
to input/output devices using standard .EIA logic levels,
i.e. dataphone.

Multi Station Teletype Interface (Type LTl9D).

1.1

Addition of the LT19D option to the PDP-9 expands
the machine's teletype facility to accommodate up to
five optional teletype control units. The LT19D consists
of the following:
a.

The LT19 D,E,F system consists of an interface to
the processor (LTl9 D) and up to five teletype
control units.
(LTl9E,F).

Two standard 19" DEC Type 1943 mounting panels
(c~mpletely bussed and prewired for PDP-9
10 Bus interfacing and the insertion
of up to five independent teletype controls,
LT19E"s or LTl9F's defined below).
All of the logic modules necessary to
interface the control units to the
standard PDP-9 10 Bus.

One to five optional LTl9E(F) teletype control
units may be added to each LT19D interface.
1.2

Each of the LTl9E(F) control units (up to five may
be used) is optional - directly pluggable i:nto the
LTl9D interface.

1.3

The LT19D is packaged in two standard DEC #194119" lOgic IT'ounting racks. Up to five LTl9E(F)
control units may be plugged into the LTl9D logic
racks.
(lO~" of mounting space is required).

Optional Teletype Control (Type LT19E)
The LT19E is a group of standard DEC logic modules
which, when inserted into the appropriate locations
of an LT19D, constitu~e a Single independent teletype control with the following specifications;

*

a.

five or eight

b.

one unit start code.

c.

1, 1.5 or 2

d.

c.

Speed variable to 30 K baud.

f.

MaxUnurn signal transmission di5tance is 2000 feet with
teletype units, 250 feet ::m LTl9F units with LT19H option.

g.

LT19E teletype contr~ls may. be used with ASR, KSR,
RO or SO teletype units.

*

When the LTl9D, E (F) options are added to c PD?-9
system, these 1943 logic mounting racks must be
added to the system as shown in section 4.0 and
all neces3ary cable connectors and power wiring
should then be added.

1.4

The LTl9D,E,F,H options operate reliably ~ver the
temperature and hwnidity range specified for the
processor. Each L'l'19D,E,F,II optional system is

Set-Up Procedure
12.1

Set up all ll¢ Baud Teletype channels with the
required Machin0 (KSR 33 or 35) and checkout with the
current version of the diagnostic (LT¢9l9).

12.2

Set up all channels with Level Converter options
(L~l9F) and run the self checking test as directed
in the diagnostic addendum, D8CC-DN.

12.3

LT19H Set up.

12.4

Recommendations for setting up
each channel.

Refer to the spec. LTl9H.
R4~1

clocks for

a.

Set up the Transmit clock first since it
is free-runnlng.

b.

Remove the W7~6 Receiver Module, this will
allow the receive clock to free run.
Set
the scope to ALTERNATE Sweep,
INT. Trigger,
do NOT trigger on CHI. This will allow
the pulses from the receive clock to be
matched to the transmit clock.

Additional notes for ll~ Baud Channels. At ll~
Baud each data bit is 9.09 MS long,
this requires
the R4~1 clock to be set to 4.545 MS rate. There
are 11 bits of 9.09 MS in each character, therefore a
charucter is l~~ MS long.
Since it would be very
difficult to measure a clock interval of 4.545 MS
on a scope, set up to measure an Intire character (100115).
The scope calibration can be easily checked by putting
six (6) complete cycles of 60 cycle waveform in exactly
l¢CM. With the scope calibrated to l~~ MS, fine tune
the R4~1 to give 23 clock pulses in l~CM (22 clock
pulses plus the first pulse of the next character.)
