1.3 FUNCTIONAL DESCRIPTION
The KMSI11-BD/BE synchronous communications processor is a complex, high-speed microprocessor
which can be used to implement custom'netWGrkmg applications. The KMS11-BD/BE communications
processor provides high-speed, efflclent communications between the processor and up to eight serial synchronous lines.

1.3.1 KMSI11-BD/BE Synchronous Comminucations Processor
The KMS11-BD/BE communications processor can be used to establish a communications link in a variety
of different applications ranging from terminal cluster controller support to full interconnection between
remote operating systems, application programs and peripheral devices. The KMS11-BD/BE communications processor is particularly suited for use in fully connected and star type topologles where the requirements for multiple line connections exist.

1.3.2 KMC11-B Auxiliary Processor
The KMC11-B auxiliary processor provides the UNIBUS interface and connection to the line termination
unit. This microprocessor controls I/O operations of the synchronous line units that require extensive intelligence, such as data communications
and analog 1/0.
1.3.3 DMSI11-DA Synchronous Line Unit
The DMSI11-DA synchronous line unit contains eight individual interface circuits that take care of the
serial-to-parallel and parallel-to-serial conversion of the data. The interface circuits also verify that bit
shifting and flag and frame checking sequences are performed properly.
1.3.4 DM11-BA Modem Control Multiplexer
The DMI11-BA modem control multiplexer provides a separate UNIBUS conductor interface for the
modem control signals required to operate synchronous lines. The DM11-BA multiplexer can be controlled
by either host software or KMC11-B auxiliary processor firmware.
When the modem control multiplexer is controlled by the KMCI1 1-B auxiliary processor, interrupts from
the DM11-BA multiplexer to the host are disabled, and the KMC11-B auxiliary processor reads and writes
modem control registers. The auxiliary processor polls the modem control multiplexer looking for transi-

tions in modem control lines, and initiates modem action when these transitions take place.

When the modem control multiplexer is not controlled by the auxiliary processor, interrupts from the multiplexer to the host are enabled, and the host controls the modem control registers. When transitions in the
modem control lines occur, the modem action is then automatically controlled by the host.

1.3.5

H317-M Distribution Panel

The H317-M distribution panel combines the modem control signals, data from the modem control unit,
and line termination units into a single, unified set for each of the eight lines. Jumpers on the distribution
panel provide a means to set up individual modem control configurations. All interface signals are EIA
RS-232-C/CCITT V.24 and V.28 compatible.
1.3.6

H317-P Distribution Panel

The H317-P distribution panel combines the modem control signals, data from the modem control unit,
and line termination units into a single, unified set for each of the eight lines while maintaining strict electromagnetic interference (EMI) shielding integrity. This distribution panel is downward compatible with
the H317-M distribution panel. The H317-P is made up of two parts, the I/O panel modules (7019648-01)
and the 1/0O panel frame (7426409-01).

CHAPTER 2
SITE PREPARATION
AND INSTALLATION

2.1

INTRODUCTION

This chapter describes the installation, setup, and configuration for the KMS11-BD/BE synchronous communications processor. It also describes the various revision levels for the KMS11-BD/BE communications
processor.

2.2

OPERATING ENVIRONMENT

The operating environment of the KMS11-BD/BE synchronous communications processor is made up of
three elements. These elements are as follows:
e

Physical elements (Section 2.2.1)

Environmental elements (Section 2.2.2)

Grounding elements (Section 2.2.3)

2.2.1

Physical Elements

The KMS11-BD/BE communications processor requires adequate space for mounting the following:
e

BA11-K nine-slot expander box
CAUTION
To ensure proper air circulation for cooling purposes, one blank slot must be left between each board
when placed in the DD11-DK backplane. (Refer to
Figure 3-2 for proper module placement.)

Either the H317-M distribution panel, or the H317-P distribution panel.

BA11-K Expander Box

The expander box requires a 63.5 cm X 45.7 cm X 26.7 cm (25.0 in X 18.0 in X 10.5 in) area to enable
.

proper mounting within the cabinet.

H317-M Distribution Panel
The H317-M distribution panel requires a 13.30 cm X 48.30 cm (5.25 in X 19.00 in) area for rack mounting. The H317-M distribution panel must be mounted within 3.3 m (10.0 ft) of the BA11-K expander box.
H317-P Distribution Panel

The H317-P distribution panel requires a 13.30 cm X 48.30 cm (5.25 in X 19.00 in) area for rack mounting. The H317-P distribution panel must be mounted within 3.3 m (10.0 ft) of the BA11-K expander box.

2-1

2.2.2 Environmental Elements
The KMS11-BD/BE communications processor is designed to operate in a “Class B” environment. A
“Class B” environment meets the following prerequisites:

Temperature — 10°C to 40°C (50°F to 104°F)

Relative Humidity - 10% to 90%

Maximum Wet Bulb - 28°C (82°F)

Minimum Dew Point - 2°C (36°F)

2.2.3

Grounding Elements

Careful grounding is essential in order to avoid ground loops and poor noise rejection. To eliminate ground
loops and to have proper noise rejection, ensure that:
®

The KMSI1-BD/BE processor and all equipment that it connects to shares a common ac power
source.

No electrically noisy equipment shares the same power source.

The earth ground of the KMS11-BD/BE processor and all modem earth grounds are common.

H317-M Grounding

The normal grounding system used on the H317-M distribution panel (Figure 2-1), J1 through J8, is as
follows:
®

Pin 1 (EIA protective ground) is connected directly to the circuit/frame ground.

Pin 7 (EIA signal ground) is connected directly to circuit/frame ground.

H317-M Jumpers
After the H317-M distribution panel is physically installed, ensure that the W10, W12, W14, W16, W20,
W22, and W24 ground jumpers are installed. (Refer to Figure 2-1 for jumper locations.)
|

NOTE
Jumpers W1 through W8 must be installed in order
to run the KMS11-BD/BE processor diagnostics.
H317-P Grounding

The H317-P distribution panel (Figure 2-2) is shipped with jumpers W2, W4, W6, and W$ installed on
cach I/O panel module. This connects pin 1 of each EIA connector to the KMS-11 processor circuit

H317-P Switch Settings
The switchpack (Figure 2-2) on each I/O panel module controls the transmission of the maintenance clock
that is generated by the KMS-11 communications processor. These switches must be ON to run KMS-11
communications processor diagnostics. The switch numbers on each switchpack correspond to the line
member on that module.

NOTE
If these switches are OFF, the diagnostics will fail
immediately since the maintenance clock is required
for the diagnostics to run.

CHAPTER 3

SYSTEM CONFIGURATION

3.1 INTRODUCTION
This chapter is designed to give a basic understanding of how the KMS11-BD/BE synchronous communications processor option is configured to UNIBUS connector systems and the cabling that is required

before the KMS11-BD/BE communications processor can be installed.

3.2 SYSTEM CONFIGURATION
The KMS11-BD/BE communications processor option is an intelligent, eight-line, communications interface that can be configured on UNIBUS connector systems. (Refer to Figure 3-1 for the UNIBUS connector configuration.)

The KMS11-BD/BE communications processor (Figure 3-1) consists of:
A KMCI11-B general purpose microprocessor,

A DMSI11-DA line unit,
A DM11-BA modem control multiplexer, and
e

Either an H317-M or H317-P distribution panel.

When configuring the KMS11-BD/BE communications processor option to UNIBUS connector systems,
the DD11-DK backplane is used. The DD11-DK backplane is a nine-slot backplane that accommodates all
of the KMS11 communications processor option boards.
CAUTION
To ensure proper air circulation for cooling purposes, one blank slot must be left between each board
when placed in the DD11-DK backplane. (Refer to
Figure 3-2 for proper module placement.)

CHAPTER 4
MAINTENANCE

4.1 INTRODUCTION
This chapter will aid the user in performing limited maintenance on the KMS11-BD/BE synchronous communications processor. This chapter is not intended to give the user a complete listing of troubles and their
solutions. Instead, it will assist the user in determining which diagnostics to use when checking the KMS11-

BD/BE communications processor.

4.2 MAINTENANCE PHILOSOPHY
Since the KMS11-BD/BE communications processor is a complex, high-speed, intelligent communications
interface that is densely packaged and mounted in the DD11-DK nine-slot backplane, maintenance to be
performed on the unit is limited to the running of diagnostics.

Should a failure occur while running diagnostics, call field service. Field repair of the KMS11-BD/BE
communications processor is not to be attempted under any circumstances.

4.3 SPECIAL TOOLS AND EQUIPMENT
There are no special tools or special equipment needed to perform user maintenance on the KMS11-BD/BE
communications processor.
4.4 PDP-11 SYSTEM DIAGNOSTIC SOFTWARE
This section lists the diagnostic software that is used to verify proper operation of the KMS11-BD/BE
communications processor when interfaced to a PDP-11 system. Also contained in this section is a basic
description of the diagnostic tests and the sequence in which the diagnostics are to be run.

The diagnostics used are:

CZKMB (YM-Z093D-A) — Section 4.4.1

CZKMC (YM-Z093D-B) - Section 4.4.2

CZKMD (YM-Z136D-1) - Section 4.4.3

CZKME (YM-Z136D-2) - Section 4.4.4

CZKMG (YM-Z138D-A) — Section 4.4.5

CZKMF (YM-Z136D-3) — Section 4.4.6

CXKMA (YM-Z093D-X) - Section 4.4.7

CXDMS (YM-Z138D-X) — Section 4.4.8

4.4.1 CZKMB (YM-Z093D-A)
The CZKMB is the first diagnostic run when testing the KMS11-BD/BE synchronous communications
processor. This diagnostic should be run in conjunction with CZKMC in order to test the logic circuits on
the KMC11-B general purpose UNIBUS microprocessor. In order for the KMC11-B microprocessor to
pass this diagnostic, a minimum of 10 consecutive error-free passes must be run.
The CZKMB diagnostic tests from 1 to 64 KMC11-B microprocessor modules. The CZKMB diagnostic
runs under the diagnostic run-time services (DRS). CZKMB consists of sequential logic tests that are used
to verify most of the KMCI11-B microprocessor logic circuits.
Equipment Requirements

A PDP-11 microprocessor with at least 16K of memory,

A console device (such as an LA36, LA120, LA34, or VT100), and

A KMCI11-B general purpose UNIBUS microprocessor.

4.4.2 CZKMC (YM-Z093D-B)
CZKMC is the second diagnostic run when testing the KMS11-BD/BE synchronous communications
processor.

The CZKMC diagnostic tests from 1 to 64 KMC11-B microprocessor modules. It runs under the diagnostic run-time services (DRS) and consists of a set of sequential logic tests used to verify the logic circuits of a
KMC11-B microprocessor. The CZKMC is run after and in conjunction with diagnostic CZKMB.
CZKMB and CZKMC verify proper operation of all KMC11-B microprocessor logic circuits.
Equipment Requirements
®

A PDP-11 microprocessor with at least 16K of memory,

A console device (such as an LA36, LA120, LA34, or VT100), and

A KMCI11-B general purpose UNIBUS microprocessor.

4.4.3 CZKMD (YM-Z136D-1)
CZKMD is the third diagnostic run when testing the KMS11-BD/BE synchronous communication
Processor.

The CZKMD diagnostic tests the line unit for both character-control protocol (CCP) and bit-oriented protocol (BOP) modes while in either the USYRT maintenance mode or external mode. This CZKMD diagnostic exercises the line unit without resident firmware in the KMC11-B UNIBUS microprocessor.
Equipment Requirements

A PDP-11 microprocessor,

A console device (such as an LA36, LA120, LA34, or VT100),

A DMSI11-D line unit.

4.4.4 CZKME (YM-Z136D-2)
CZKME is the fourth diagnostic run when testing the KMS11-BD/BE synchronous communication
processor.

The CZKME diagnostic tests the line unit in either bit-oriented protocol (BOP) or character-control protocol (CCP) mode using internal USYRT maintenance mode or external loopback connectors. These options
are selected by responses to questlons asked by the diagnostic during startup or by entering the configuration mode. The CZKME diagnosticis a stand-alone routine which tests the hne unit with resident firmware
in the KMC11-B general purpose UNIBUS microprocessor.
Equipment Requirements

A PDP-11 microprocessor,

A console device (such as an LA36, LA120, LA34, or VT100),

445

CZKMG (YM-Z138D-A)

CZKMG is the fifth diagnostic run when testing the KMS11-BD/BE synchronous communications
processor.

CZKMG tests the DM11-BA modem control multiplexer. The CZKMG diagnostic is functionally divided
into the following groups:

Group 0 - All line scanner and line multiplexer functions are tested using either the H317-M or
H317-P distribution panel with H3256 test connectors in place of the modem cables or with
54-14700 or 2M-E122A loopback connectors.

Group I - A single line is tested using either the H317-M or H317-P distribution panel with

H3256 test connectors in place of the modem cables or with 54-14700 or 2M-E122A loopback
connectors.

Group 2 - Not applicable.

Group 3 - Connect/disconnect test for 202C compatible modems.

Equipment Requirements

A PDP-11 microprocessor with at least 8K of memory,

A console device (such as an LA36, LA120, LA34 or VT100),

A DMII-BA modem control multiplexer,

FEither an H317-M or H317-P distribution panel, and

A 54-14700, 2M-E122A, or H3256 test connectors.

4.4.6 CZKMF (YM-Z136D-3)
CZKMF is the sixth diagnostic run when testing the KMS11-BD/BE synchronous communications
processor.

The CZKMF diagnostic tests the interaction between the DMS11-DA communications controller and the
DMI11-BA modem control multiplexer. The CZKMF diagnostic is functionally divided in the following
groups:

Group 0 - All line scanner and line multiplexer function tests use the H3256 test connectors
with either the H317-M or H317-P distribution panel.

Group I - A single line is tested using either the H317-M or H317-P distribution panel with the
H3256 test connectors in place of the modem cables.

Equipment Requirements

A PDP-11 microprocessor with at least 12K of memory,

A console device (such as an LA36, LA120, LA34, or VT100),

A DMI11-BA modem control multiplexer,

A DMSI11-DA line unit,

A KMSI11-BD synchronous communication processor, and

A 54-14700/2M-E122A and 54-14698/2M-E044A or a H3256 test connector.

4.47 CXKMA (YM-A093D-X)
CXKMA is the seventh diagnostic run when testing the KMS11-BD/BE synchronous communications
processor.

The CXKMA DEC/X11 module exercises up to two consecutively addressed and consequently vectored
KMC11-B microprocessors. CXKMA does not use any line units for receiving and transmitting data. The
data is transmitted and received from the PDP-11 system memory to the KMC11-B microprocessor and
vice versa.
Equipment Requirements

The ZZ-EVDHA diagnostic contains 20 tests which establish the functionality of the KMC11-B microprocessor. All pertinent bits are tested for their ability to be set and then cleared. All registers and memory
locations are tested to verify that they can be accessed and that they do retain the data placed into them.
Where necessary, all registers and memory locations are checked to verify that no two addresses or registers answer to the same address. The arithmetic line unit (ALU) is tested, first with the ALU carry bit

cleared and then with ALU carry bit set. The entire board is then tested where all pertinent register/
memory addresses are accessed together and a verification is made that all internal data paths are functioning correctly.
Equipment Requirements

A VAX-11 microproceséor with at leasf 128K of memory,

A KMCI11-B microprocessor, and

A UNIBUS connector adapter.

4.6.2 7ZZ-EVDKA
Z27-EVDKA is the second diagnostic run when testing the KMS11-BD/BE synchronous communications
processor.

The ZZ-EVDKA is the DMS11-DA line unit repair level (level 3) diagnostic. The 7Z-EVDKA diagnostic

tests one to eight lines in a closed loop environment. The line unit is driven by the KMC11-B UNIBUS
microprocessor without resident firmware. The DMSI11-DA line unit should be tested using the
AA-EVDKA diagnostic before any dynamic KMSI1 1-BD communications processor testing is performed.

Equipment Requirements

A VAX-11 microprocessor‘ with at least 128K of memory,

A KMCI11-B microprocessor,

A DMSII1-DA line unit, and

A UNIBUS connectoradaptor.

463 ZZ-EVDIA

Z7-EVDIJA is the third diagnostic run when testing the KMS11-BD/BE synchronous communications

processor.

ZZ-EVDIJA is the DM11-BA modem control multiplexer repair level (level 3) diagnostic. The ZZ-EVDJA
is a component of the KMS11-BD communications processor option, but it can be tested independently,
using only the H317-M distribution panel. The diagnostic is divided into the following functional tests:

Default Section — All line scanner and line multiplexer functions are tested using the H317-M
test connectors with either the H317-M or H317-P distribution panel.

H3256 Section — A single line is tested using the H317-M or H317-P distribution panel with
H3256 test connectors in place of the modem cables.

Equipment Requirements

A VAX-11 microp‘rocessor at ECO level #3 or above and with at least 128K memory,

A DMII-BA multiplexer,

4-6

Either an H317-M or H317-P distribution panel,

One to eight H317-M test connectors, and

A UNIBUS connector adaptor.

4.6.4

7Z-EVDIA

ZZ-EVDIA is the fourth diagnostic run when testing the KMS11-BD/BE synchronous communications
processor.

ZZ-EVDIA checks the functionality of a KMC11-B microprocessor interfaced to a DMS11-DA line unit.
The operator may select from one to eight lines on the DMS11-DA line unit to be tested. ZZ-EVDIA
provides error messages which identify failing functions which aid in the repair of the device. The
Z7Z-EVDIA diagnostic uses loopback to test data thru-put facilities. The loopback is internal to the
DMSI11-DA line unit unless the operator selects to use external mode. ZZ-EVDIA stores, loads, and tests
separate KMC11-B microprocessor firmware protocols.
Equipment Requirements

A VAX-11 microprocessor with at least 128K of memory,

A UNIBUS connector adaptor,

A KMCI1-B microprocessor,

A DMSI11-DA line unit,

FEither an H317-M or H317-P distribution panel, and

only).

ZZ-EVDHB

ZZ7Z-EVDHB is the fifth diagnostic run when testing the KMS11-BD/BE synchronous communications
processor.

ZZ-EVDHB tests the functionality of the KMC11-B microprocessor in a VMS environment. Special diagnostic firmware is loaded into the KMC11-B microprocessor and used to transmit, receive, and check data
buffers of 512 characters. One pass is defined as 128 interactions of the sequence.
Equipment Requirements

4.6.6

A VAX-11 microprocessor with at least 128K of memory,

A UNIBUS connector adaptor, and

A KMCI11-B general purpose UNIBUS microprocessor.
ZZ-EVDIB

ZZ-EVDIB is the sixth diagnostic run when testing the KMS11-BD/BE synchronous communications
processor.

The ZZ-EVDIB tests the functionality of the KMC11-B microprocessor interfaced to a DMS11-DA line
unit. The operator may select from one to eight lines on the KMS11-BD processor to be tested. ZZ-EVDIB
