CHAPTER 1
INTRODUCTION

The Communications Minireference manual provides Field Service Personnel, trained in
DIGITAL's communications options, with an easy-to-use manual that zeros in on essential
installation and maintenance considerations concerning some of the more popular options.
To effectively use this reference manual, it is important that the user understand the organization
and format in order to quickly locate the desired information. For example, Chapter 2 contains
option specific installation and maintenance data on selected options. In this first printing, six
options are included: DHll,DMCll,DMRll,DPVll,DUPll, andDZl1. More options will
be added through periodic updates and new releases.
Note that the option specific data of Chapter 2 is placed in alphabetic order, by option designation;
that is, DHII followed by DMCll, DMRII throughDZII. Note also, that the page numbering
system, as well as table numbers, are consecutively numbered using the option designation as a
prefix (for example, DH-l, DH-2, and so on, to the end of the section).
Edge tabs identified by option designation and running headers at the top of each page (identifying
INSTALLATION, CABLING, DIAGNOSTICS, MAINTENANCE AIDS, and so on) provide
the user with a means to quickly locate the desired option - by edge tab, and the specific data - by the
m~or headings.
Also, for consistency and familiarity, the material contained in each option specific section is
organized and presented in the same format and sequence; installation data (which includes
module outline drawing, device/vector address selections, and various other switch/jumper
selectable options) is presented first. This material is followed by cabling diagrams, diagnostics
(PDP-II, VAX-II or both), maintenance aids, register bit assignments, and a Tech-Tips/FCO
index.
The remaining chapters of this manual contain generic information dealing with more than one
option. For example, Chapters 3 and 4 contain a variety of cables and test connectors used in
communications configurations. The cross reference Where Used Tables at the beginning of
chapters 3 and 4 quickly identify which cables or test connectors are used with each option.
Outline drawings of each cable or test connector are also placed in alphanumeric order, by part
number, for easy reference.

COMMUNICA TIONS DEVICES

2.1 INTRODUCTION
This chapter contains all information needed to configure, install, and test a number of
DIGITAL's communications devices.

The purpose of this chapter is to provide Field Service personnel, trained in servicing communications devices, with a quick reference guide, highlighting the important factors concerning
installation and maintenance. The information contained in these sections, therefore, is short and
to the point. If more detailed information is needed, reference should be made to the Microfiche, Technical Manual, or other reference material concerning that particular device.
Each device specific section contained in this chapter is organized in alphanumeric order. Edge
tabs, identified by the device mnemonic, are also provided for easy reference.

DUll DIAGNOSTICS
CZDHM Diagnostic Summary - The CZDHM includes 44 tests to verify all of the functional
logic and 4 additional tests for limited modem control testing. Each line may be tested separately, up to a total of 256 lines. Comprehensive error reports are available for complete fault isolation (see program document).
CZDHN Diagnostic Summary - The CZDHN is a general purpose test and exerciser that consists of the following three independent subprograms:
• Subprogram 1 - Data Reliability Test (Starting Address 200). Checks up to 16
DH lis, all lines one at a time, using various combinations of line parameters.
• Subprogram 2 - Single Line Echo Test (Starting Address 214). Provides the capability to compose messages sent to an attached terminal or messages echoed from the
terminal.
• Subprogram 3 - Data Patterns/Cable Tests (Starting Address 220). Provides a variety of data patterns to be transmitted and turned around using an H315 Test Connector at the cable end.
NOTE
To use default parameters, start at address 204.

DZDHK Diagnostic Summary - The DZDHK is a Modem Control diagnostic that consists of
the following four test groups:
Group 0-

Tests all scanner and line multiplexer functions.

•

Group I -

Tests a single line using modem cable and H315 test connector.

•

Group 2-

Connect-Disconnect test for 103A modems.

•

Group 3 -

Connect-Disconnect test for 202C modems.

•

Running DHll Diagnostics
Two procedures (One for running CZDHM and CZDHN: one for DZDHK) for running DHII
diagnostics are provided as follows.
CZDHN and CZDHM diagnostics can be executed automatically using the internal autosizer
routine by setting SWR Bit 0=0. These diagnostics can also be executed manually (where operator intervention is needed to enter correct parameters), by setting SWR 0 = I. CZDHM can
also be executed without the modem control tests by setting SWR 10= I.
Running CZDHM and CZDHN Diagnostics - The following summarizes running DH II diagnostics. Tables DH-5 through DH-8 pruviae descriptions of the parameter inputs for each of the
diagnostics.

DMR 11 INSTALLATION
Device Placement
The OMR II requires two hex-height, small peripheral controller (SPC) backplane slots (preferably two adjacent slots). Any SPC backplane [OOII··B(REV E) or later] can accept the
OMRII. The 0011-0 can accommodate a maximum configuration of three OMRIIs.
Applications using speeds greater than 250K bjs require UNIBUS placement before all UNIBUS repeaters and before all devices that have a lower NPR rate on the UNIBUS.
REMOVE NPG JUMPER FROM SELECTED M8207 SLOT (PINS CAl TO CBI).
NOTE
In configuration where both DMClls and DMRlls are used, DMCs
must be plnced before DMRs (since they share the same rank).

system.

DS> LOAD EVDXA
Example shown is DMCjDMR
DS> AfT DMRII *

NOTE
This command now enters the hardware parameter information for
the device (refer to the following Table DMR-6 for Typical Hardware Parameters). When the various hardware parameters are qualified, the program returns to the supervisor level of operation and the
following steps must be followed:
4.

SELECT the devices that have
been attached to the system.

DS> SELECT ALL or
DS> SELECT DWO and
DS> SELECT XMO

5.

SET the appropriate event.

DS> SET EVENT FLAG(s) n,n,n.

6.

If a printout of the tests
being executed is desired,
then the trace flag can be
set by SET TRACE command
for the program (if applicab\c). Now the program may
be started by the START
command.

DS> SET TRACE
DS> START

VAX-lljDUPll DIAGNOSTICS
Running VAX-lljDUPll Diagnostics - The following summarizes running VAX-IljDUPII
diagnostics.
Table DUP-6

Typical VAX-lljDUPll Program Operation

Command Function

Example

i.

Load appropriate diagnostic

DS> LOAD EVDUP or EVDUQ

2.

ATTACH the UNIBUS interface
(UBA or UBI) to the system
bus.

DS> ATT DW780 SBI DWO 3, 4, or
DS> ATT DW750 CMI DWO

3.

ATTACH the device to the
system.

OS> ATT OUPII

NOTE
This command now enters the hardware parameter information for
the device (refer to the following Table DUP-7 for Typical Hardware Parameters). When the various hardware parameters are qualified, the program returns to the supervisor level off operation and the
following steps must be followed:
4.

SELECT the devices that have
been attached to the system.

OS> SELECT ALL or
OS> SELECT OWO and
OS> SELECT XMO

5.

SET the appropriate event.

OS> SET EVENT FLAG(s) a,n,n.
(EVOUQ only)

6.

If a printout of the tests

OS> SET TRACE
OS> START

being executed is desired
then the trace flag can be
set by SET TRACE command for
the program, if applicable.
Now the program may be
started by the START command.

Running PD P-II /D Z II Diagnostics - The following summarizes running DZ 11 diagnostics.
Start pllOgram:
• At address 000200 for normal testing, or
• At address 000210 for ECHO/CABLE testing.
Set Switch Registers:
For 000200
• SWO = 0 Auto Size
• SWO = I Initial start (manual input)
• SW7 = I No auto size (uses previous parameters)
For 000210
• SWO = I Manual input
• SWI = I Invokes ECHO/CABLE parameters
If program is started at address 200 with SWO = 1, the program prints the diagnostic name,
followed by the parameter functions, and then the status map.

4.1

GENERAL

This chapter contains outline drawings and turnaround signal flow diagrams of each of the test
connectors needed to test any of the device options contained in this manual. The following
Where Used cross reference chart quickly identifies which test connector (or terminator) is used
with each device option.
Test connectors are included in this chapter in alphanumeric order for easy reference. Note that
some of these test connectors are used in more than one application.

SPECIAL TEST PROGRAMS

5.1 INTRODUCTION
This section includes a brief description of the diagnostic packages that typically test intersystem communication links such as the Data Communications Link Test (DCLT) and the Interprocessor Test Program (ITEP).
Both DCLT and ITEP contain special expanded command features which are device dependent
(for example, printing the base table under DMRjDCLT). Other variations in features and
functionality (such as the HELP files for each specific DCLT) are also device dependent.

5.2 DATA COMMUNICATIONS LINK TEST (OCLT)
DCL T programs provide Field Service personnel with a tool to verify communications links for
many of the options contained in this mini reference manual. DCLT programs also provide the
coverage necessary to isolate faults in the following areas:
• Communications interface program functionality,
• Communication modem,
• Communication cabling and installation, and
• Physical link/network.
DCL T programs allow testing between nodes with different hardware interfaces implementing
the same or compatible protocol. The DCLT program can be exercised under normal maintenance loop back tests:
•

I nternal TTL loop back,

• Hardware loop backs:
-

module test connectors, or

-

cable test connectors,

• Manual controlled local modem analog and digital loop back functions (full-duplex
mode),
• Programmable controlled local modem analog loop back (RS-449 only and full-duplex
mode), or
• Programmable controlled remote modem digital loop back (full-duplex mode).
5-1

5.2.1 Hierarchy Prerequisites
Before using DClT to test the communciations link it is important to verify that the CPU's line
clocks an: operational. In addition, it is important to verify that the devices at each end of the
link have previously been tested by device specific diagnostics and found to be in working order.
Prior to analyzing any data, the user should have a thorough understanding of the protocol formats applicable to the system under test.

5.2.2 System Requirements

I

I

I

To run th~ DCLT program, the following minimum hardware/software is required:
•

PDP-II or VAX-II CPU,

•

Minimum memory requirements:
-

28K words for PDp··II systems,

-

256K bytes for VAX-II systems,

•

Any supported XXDP+ load media,

•

A working line or real-time clock,

•

Diagnostic supervisor, and

•

A communications device to test.

5.2.3 Program Structure
The DClT program is written to be used with the diagnostic supervisor. Some communications
options are supported by a DClT program designed to test the communications link for that
option. For each individual program, hardware and/or software P (Parameters) Tables are available to establish certain conditions. All DClT programs use a command line interpreter (CLI)
that may utilize anyone of three DClT command types:
•

Run Commands - (detailed in Tables 5-1 and 5-2),

•

Message Commands - (detailed in Table 5-3), or

• Statistical/Utility Commands _. (detailed in Table 5-4).
Any DClT command may be followed by its associated switch and/or qualifier. In the event of
an illegal command, the program will output an error message to the console.
Six sequential subroutines are normally peformed during the normal DCl T run command operation:
• Device Initialization,
•

Mode Set-Up (set FLAG word),

•

Receive Buffer QUE/START,

• Transmit Buffer Que/START,

5-2

June 1982

• Data Comparison (only if data check has been enabled), and
• Program PASS Completion.
Along with these six subroutines the DCLT program can also perform special routines which
may be device specific:
• DCLT down-line load test (only if supported by the device being tested), and
• Talk/Listen Mode
-

Talk/Listen mode is used for operator communication requiring line turnaround
in half duplex.

-

Talk mode allows the user to type his own message of up to 72 characters.

-

Listen mode allows the user to look for receive data and display up to 72 characters on the console.

-

If the first four characters of message are "EXIT", the program will switch to the
other mode automatically at both ends of the link.

Format

.Description

1. R M=A/S/CH/L=C/P=5

Program runs in Active mode, allows status printouts, does data comparisons, loop data at cable
(test connector required), and does 5 complete
passes before completing test.

2. R M=A/SjM/L=IjP=2

Program runs in Active mode, allows status printouts, loops data internally, and makes 2 passes.

3. R M = P /NOCH/S/NOE/NOM/

For half-duplex, one node must be active and the
other passive. Set the passive node first as shown
in the example. The active node can then be set
up, as shown above.

L=C/P=2*
4. R M=AjSjCH/L=CjP=-1

Program runs in active mode, allows status printouts, does data comparisons, loops data at the
cable (test connector required), and makes continuous passes until a control C is typed by the
user.

If no entry is made for a certain qualifier function (such as NO CHECK qualifier in Example 3)
in the command string, the default is the previously-entered qualifier for that function. In Example 2, data comparisons would be done because the CHECK function (as opposed to NOCHECK) was previously established in Example 1. When that qualifier function is changed, it becomes the default entry for subsequent command strings when no entry is made.

* Command strings must be single line.

5.2.5 Running PDP-II/DCLT
When the DCLT program is started, the diagnostic supervisor will prompt the user for hardware
information by typing:
CHANGE HW (L)?
The "L" in brackets indicates the type of response required, "L" indicates that a logical answer
("Y" for yes or "N" for no) is needed. In this case, the user must respond with a "Y" after a
start command unless the hardware information has been "preloaded" using the SETUP utility.
Next, the supervisor will prompt:

# UNITS (D)?
The "D" indicates that a decimal response is needed. The DCLT program will not use more
than one unit and therefore will not accept any response greater than "1." Typical PDP11jDCLT procedures are provided in Table 5-7.
This example is typical for DMCjDMR; however, P table questions are option-dependent and
may differ. Refer to option specific section in Chapter 2 for details.

5.2.6 Running VAX-Il/DeLT
The V AX-II Data communication Link Test (DCLT) Programs are level 2 programs that execute either under VMS (on-line) or in standalone mode. The DCL T programs require the standard VAX-II system attaching for the device to be tested. Table 5-8 details typical VAX-II
DCLT pl'Ogram operation. Hardware device parameters are requested after the device is attached (refer to the Typical V AX-!I DCL T Hardware parameters, Table 5-9). The event flags
utilized by the DCLT program help to describe the internal configuration of the hardware
and/or special program functions. These event flags are dependent on the specific device and
are listed in a device specific DCL T table.
NOTE
The promllt DS> indicates a V AX-It Diagnostic Supervisor Commall1d is required.

5.3 INTERPROCESSOR TEST PROGRAM (ITEP)
ITEP is a software tool to test the communications link between two devices. To run ITEP on
any of the supported devices, the ITEP Monitor DZIT A must be loaded along with the correct
ITEP overlay (device specific).
ITEP features:
• Communications between two devices over remote or local links.
•

Interfaces with the Merrimack turnaround system.

•

Uses programmed or operator generated messages.

•

Monitors transmitted and/or received messages with optional print capability.

• Operates in one of four basic modes:
One Way In
One Way Out
Internal loopback
External loopback

Receive only
Transmit only
Receive followed by Transmit
Transmit then idle Receive

Table 5-11 lists each of the overlays currently available to support the options indicated. Table

SPECIAL TOOLS AND EQUIPMENT

6.1 INTRODUCTION
This chapter provides brief descriptions of various special tools and test equipment available to
aid in troubleshooting and testing DIGITAL's Communications configurations. The following
are presently available and being used:

• IDS Model #60 Interface Monitor/Breakout panel,
• Astrocom, Minicheck Data Transmission Test Set, and
• DIGITAL's Communication Turnaround System.

6-1

6.2 BREAKOUT PANEL
The Model 60 Breakout Panel is a multipurpose tester that provides access to RS-232-C signals.
It featun~s:

• Switch packs and patchable jumper pins (one for each line) allowing signal interruption and/or rerouting;
•

12 LEDs to monitor certain key functions; and

• Two additional LEDs to check voltage levels greater than ± 3.5 Vat any line Uumper selectable).

.•-_.~IM~I~N!!IC;.!!H~E:gg~CK!I
, IMODEMH f--IMOi)EMJ~

Test Procedure

6.3.2

Step 1

Disconnect modem from operating device and connect Minicheck tester to
modem.

Step 2

Apply power to Minicheck and modem, and sct Minicheck speed to the same
speed as the modem. For test configuration 3, make sure that both Minicheck
tests are set to the modem speed.

Step 3

Set RTS and DTR to the ON position. For test configuration 3 place one tester
RTS to ON and the other to OFF. To test the opposite direction, reverse the
RTS settings and repeat the test procedure.

Step 4

For test configuration 1, place modem in analog loop, if available. [n test configuration 2, place the remote modem (one without tester) in REMOTE
TEST. For test 3, go to step 5.

Step 5

Select the desired test pattern in test configuration 3, the test pattern must be
the same at both testers.

T4~st

Results

Configuration 1 and 2
I. CO and CTS indicators should be ON.
2. RD indicator should be:
a. ON for MARK pattern,
b. OFF for SPACE pattern,
c. Dimly lighted for AL T pattern,
d. Flickering for RANDOM pattern.
3. Error count after initial synch should be stable.

6-4

4. Check status of interface leads by:
a. Using an Oscilliscope, or
b. Connecting the TEST lead to the desired interface lead. Results are indicated in the
+ TEST - area of the displays (plus sign lighted for MARK: minus sign lighted for
SPACE).
Configuration 3
I. Minicheck with RTS ON:
a. CTS and RD indicators ON,
b. CO indicator OFF,
c. Error count free running unless SPACE pattern selected,
d. Check interface signal status (see test results, configuration I and 2, step 4).
2. Minicheck with RTS OFF:
a. CTS indicator OFF,
b. CO indicator ON,
c. RD indicator should be:
I. ON for MARK pattern
2. OFF for SPACE pattern
3. Dimly lighted for AL T pattern
4. Flickering for RANDOM pattern.
d. Error count after initial sync should be stable.
e. Check interface signal status (see test results, configuration I and 2, step 4).

6.3.3

4.

Connect test points RD to TD, DTR to CO and RTS to CTS.
Apply power to the tester and place RTS and DTR to the ON position.
Set speed-select to 1200 (ASYNC 2).
Select desired test pattern.

Test Results:
Same as Configuration I and 2, steps 1 through 3.

6.4 DIGIT AL'S COMMUNICATION TURNAROUND SYSTEM
The communications turnaround system consists of a PDP-II 120 which offers three separate
dial-up line capabilities for remote turnaround testing. These include:
• DLlI-E operating at 300 or 1200 bls connected to a 2I2A Asynchronous Modem.
• DLl1-E operating at 1200 bls connected to a 202S Asynchronous Modem, and
• DU1I-DA operating at 2400 bls connected to a 20lC Synchronous Modem.

DEC MODEM PRODUCTS

9.1 INTRODUCTION
This chapter contains infonnation needed to configure, install, and test a number of DIGITAL's
modem products. Currently, there are two products included in this chapter; the DF02 and DF03
modems. As new modem products are developed, this chapter will be revised to include support
for those products.
The purpose of this chapter is to provide Field Service personnel, trained in servicing modem
devices, with a quick reference guide that highlights the important factors concerning installation
and maintenance. The infonnation contained in this chapter, therefore, is short and to the point. If
more detailed infonnation is needed, reference should be made to the microfiche, technical
manual, or other reference material concerning that particular device.
The options presently contained in this chapter are:
•

DF02-AA

•

DF02-AC

•

DF03-AA

•

DF03-AC

•

DF Series Rack Mount (to be supplied)

DF02/DF03 INSTALLATION
DF02/DF03 OPTION
DF02/DF03 General Description
The DF -series modems provide full duplex, asynchronous or synchronous, binary serial data
communications. This is accomplished over two-wire, switched, telephone network facilities.
Low-speed operation [0 to 300 bits per second (b/s)] is asynchronous, binary frequency shift
keyed (FSK). High-speed (1200 b/s) operation (DF03 only) can be either character-asynchronous
or bit-synchronous, quaternary differential phase shift keyed (QDPSK).
These modems are compatible with EIA-RS-232-C/CCITT V.24 and are equivalent to
103/113/212A modem series.
DF02/DF03 Standard Modem Features
The features below apply to both DF02 and DF03 modems unless otherwise specified.
•

300/1200 b/s asynchronous (DF03) 0-300 b/s asynchronous (DF02);

•

1200 b/s synchronous (DF03 only);

•

Full-duplex operation on public switched telephone network (PSTN);

•

Manual originate/answer and automatic answer for DF03-AA/AC;

•

Automatic originate for DF03-AC only;

•

Uses standard RJllC telephone rack;

•

FCC approved for direct connect;

•

Diagnostic test switches;

•

EIA RS232-C interface; and

•

DATA/TALK HIGH/LOW speed select switch.

DF02/DF03 Auto Call Features
For both DF02 and DF03:
•

Single EIA RS232-C port (shared with modem port);

•

Asynchronous ASCII data;

•

Data rates - 110, 300, 1200 b/s; and

•

Pulse code dialing.

DF02/DF03 Test Procedures
GENEIUI..L
This section provides modem checkout procedures to help isolate data communication problems
related to DF02 and DF03 modems. All test functions have simplified diagrams representing the
test features. In test features where a terminal is used, a computer system (interface) could also be
used.

The correct procedure to test and verify a modem communications link is shown in Figure 1. The
five modern test areas will be discussed in the next section.

TEST AREA 3 - ANALOG LOOPBACK TEST (FIGURES 4 & 5)
Test area 3 generally has two separate tests; one called analog loopback self-test and the other
called analog loopback. Both tests verify that the modem can transmit and receive data at the local
modem with no errors. Each of these tests are discussed below.
Analog Loopback Self· Test (DF03 Only) (Figure 4)
This test uses an internal test generator for data transmission and a test comparator on the receiver
to detect errors. If errors occur, the modem carrier LED flashes ON and OFF after the test begins.
It is normal for the carrier LED to flash once or twice at the beginning of the test. This test is not
supported on DF02.

4. Observe that the CAR LED comes ON and stays ON. This may take up to three seconds.
It may flash once or twice at the beginning. Verify that the CAR LED never flashes ag~iin
or goes OFF. If it does, the DF03 modem is defective.
5. To check the other modem speed,just change the position ofthe HS switch from its present
position. The CAR LED again flashes at first, then should remain ON as in Step 4.
6. To terminate, release the ANL and ST switches to the OUT position.
Analog Loopback Test (Figure 5)'
This test uses a data terminal or computer interface to input the test message. To verify the data,
the operator must observe that the received data is correct. This test is a very useful test, checking
both the terminal and the modem. The following describes the test procedures for each modem.

2. Configure the following test switches:

a. Set the HIGH/LOW speed switch to the desired speed-low speed (OUT), high speed
(IN).
b. Set the ANL switch to the IN position.
3. Verify that the TEST LED comes ON. Ifthe high speed was selected, the HS LED will
also come ON.
4. Observe that the CAR LED comes ON within three seconds and stays ON.
5. Type a test message on the terminal and verify that the correct data is received. Incorrect
data indicates a defective modem or wrong terminal speed.

6. To terminate, set the ANL switch to the OUT position.
TEST AREA 4 - DIGITAL LOOPBACK TESTS (FIGURES 6-9)
Test area 4 also has two separate tests (similar to test area 3) except that the test function is digital
loopback with either a self-test mode or terminal/computer test. The digitalloopback tests allow
the complete network to be checked including the remote modem logic. This test verifies the
telephone line and the receiver/transmit logic ofthe remote modem. This test does not verify any
EIA level conversion at the remote modem.
DF-33

June 1982

DF02/DF03 MAINTENANCE AIDS
DF02/DF03 Test Procedures (Cont)
The DF03 modem also has three other tests that are associated with digitalloopback. These tests
are associated with the self-test logic which uses a special switch called remote digitalloopback
(RDL). The .RDL function only works in the high-speed mode. This RDL switch allows the
operator at the local modem to cause the remote modem to automatically switch to digital
loopback without pressing the remote modem's DTL switch. No operator is needed at the remote
site. The following describes these various modem tests.
DF02 and DF03 Digital Loopback Tests (Figure 6)
PROCEDURE:
1. Verify that the DTR LED is ON.

2. Configure the following test switches:
a. Set DA TA/T ALK switch to TALK position (IN).
b. At remote DF02 modem, have someone set the DTL/ANL switch to the DTL position
(OUT). The OPERITEST switch must also be pressed to the TEST position (IN).
c. At remote DF03 modem, have someone press the DTL switch to the IN position. Set
the HIGH/LOW speed switch to the desired speed -low speed (OUT), high speed
(IN).
3. Remove telephone handset from cradle and dial the remote modem. For DF02 modems,
observe that the OH LED comes ON.
4. When answer tone is heard, set the DATA/TALK switch to the DATA position (OUT).
Place the telephone handset back on the cradle.
5. Verify the following LEDs::
a. DF02 - the CAR LED is ON.
b. DF03 -- the CAR and DSR LEDs are ON.
6. Type a test message on the terminal and verify that the correct data is received.
7. To terminate, press the DATA/TALK switch to the TALK position (IN).
8. If test is performed at computer end, repeat the above procedure. The computer modem
now becomes the local modem and the terminal modem is the remote. The computer end
will now have to generate the test message and verify the results.
9. Return the DA TA/TALK switch to DA TA position (OUT) to allow automatic answer for
incoming calls.

FLOATING DEVICE
ADDRESSES AND VECTORS

A.1 FLOATING DEVICE ADDRESSES
UNIBUS addresses 760010 (160010) through 763776 (163776) are designated as floating device addresses (see the following figure). These are used as register addresses for communications and other devices interfacing with the PDP-II, LSI-II, and VAX-II.
NOTE
Some devices are not supported by LSI-ll and VAX-ll; however,
the same scheme applies - that is, gaps are provided as appropriate.
The convention for assigning these addresses is as follows:

A gap of 108 must be left between the last address of one device type and the first address of the
next device type. The first address of the next device type must start on a module 108 boundary.
The gap of 108 must also be left for devices that are not installed but are skipped over in the
priority ranking list. Multiple devices of the same type must be assigned contiguous addresses.
Reassignment of device types already in the system may be required to make room for additionalones.

A.2 FLOATING VECTOR ADDRESSES
Vector addresses, 300 through 777, are designated as floating vectors. These are used for
communications and other devices that interface with the PDP-ll, LSI-ll, and VAX-ll. The
LSI-II floating vector area is limited to a starting address of300 through 376. The area from 400
to 450 is reserved for LSI-I I devicesADVII-A,IBVII·A,andKWVII-A with additional space
available above 450 to 777.
NOTE
Some devices are not supported by LSI-H and VAX-ll; however,
the same scheme applies. Vector size is determined by the device
type.
There are no gaps in floating vectors unless required by physical hardware restrictions (in data
communications devices, the receive vector must be on a zero boundary and the transmit vector
must be on a 48 boundary).
Multiple devices of the same type would be assigned vectors sequentially. Table A-2 shows the
assignment sequence.
