2.2.1 Control Panel Printed Circuit Board

The control panel printed circuit board is behind the molded plastic front control panel. This board provides access to the +5

V and +12 V test points. It also provides access to a line time clock (LTC) switch unit, to the restart enable switch, and to jumpers WI, W2, and W3.

The printed circuit board also contains the control panel buttons,

LEOs, and a 20-pin connector (Jl) for the backplane assembly cable. A bracket on back of the front panel holds the system power on/off (I/O) switch.

2.2.2 LTC DIP Switch Unit

The LTC labeled

Q22-Bus software

DIP (dual in-line package) switch unit has two switches

1 and 2 (Figure 2-3). Setting switch 1 to off enables the

BEVNT timing signal and lets the LTC function under control. Switch 1 is called the BEVNT Enable switch.

Setting switch 2 (Restart/Enable) to on lets the front control panel restart switch function as described in Table 2-2. Setting the Restart/Enable switch to off disables the front control panel restart switch. The Restart/Enable switch should normally be in the on position.

2.2.3 Jumpers WI, W2, and W3

The control panel printed circuit board also contains the following three jumpers.

WI -- You can set this jumper so the RDO Write Protect switch LED is inoperative (see note). RDO is the first RD3n disk drive in the BA23-A enclosure.

W2 -- You can set this jumper so the RDI Write Protect switch LED is inoperative (see note). RDl, the second RD3n disk drive, is located piggybacked on the first RD3n drive.

W3 -- This jumper is used in a BA23-C expansion enclosure to ensure that DC OK LED is directly controlled by the Q22-Bus

B DC OK H signal (see note).

2.3 MASS STORAGE

The front bezel cover spaces are for mounting mass storage devices. The top (or right) space usually contains a half-height

RX33 dual diskette drive. This space can also accommodate a TK50 tape drive or an RX50 diskette drive. This space is called port 1.

The bottom (or left) space usually contains a half-height RD3n fixed disk drive. This space is called port O.

NOTE

Two half-height fixed disk drives can be installed (piggyback style) in port O.

2.4 BACKPLANE ASSEMBLY

The MicroPDP-ll/53 system uses the same backplane assembly (H9278) as other MicroPDP-ll systems (Figure 2-5). The backplane assembly major components are the mass storage signal distribution panel and the Q22-Bus backplane.

2.4.2 Q22-BuS Backplane

The MicroPDP-ll/53 system backplane is a 10.7 inch by 4.5 inch assembly that implements the extended LSI-bus, which uses 22-bit addressing to support up to 4 megabytes of memory. This bus is commonly called the Q22-Bus.

The backplane, driven by the MicroPDP-ll/53 CPU, supports up to 22 ac loads and 20 dc loads from all modules inserted in the Q22 backplane. The ac loading is the amount of capacitance that a module presents to a bus signal line; one ac load equals 9.35 picofarads (pF). The dc loading is the amount of dc leakage that a module presents to a bus signal line; one dc load is approximately

105 microamperes (uA). The backplane itself contributes less than six ac loads « 56 pF) and no dc loads on any signal line.

The four connectors on side 2 (Figure 2-4) of the backplane provide the following functions.

Jl is an IS-pin straight single in-line connector used to supply power and signals to the backplane from the power supply.

J2 is a lO-pin connector that provides signals to the front control panel from the CPU module (KDJll-DA).

2-9


J3 and J4 are 4-pin Mate-n-Lock connectors that provide termination for the mass storage device power cable when no mass storage device is present.

For more information on the system backplane, power supply, and fans, see the MicroPDP-ll Systems Technical Manual (EK-MICII-TM).

2.5 REAR I/O DISTRIBUTION PANEL

External devices connect to the system through the enclosure's rear I/O distribution panel.

Each module that connects to an external device comes with an internal cable, a filter connector, and an insert panel. Together, these three items are called a cable kit.

The filter panels are panel. The for up to connectors. connectors mount in the insert panels and the insert installed in cutouts in the rear I/O distribution enclosure's rear I/O distribution panel provides space six insert panels, two of which can contain 50 pin

Figure 2-7 shows the rear I/O distribution panel with a typical insert panel installed. Figure 2-7 also shows the serial line unit console display panel of the KDJIl-DA CPU module, which is usually installed in the top (or left) cutout.

The items included in Table 3-3 for tapes and disks are DUO-255,

DUO-255 at floating address, DLO-3, DXO-l, DYO-l, MUO, and MSO.

For DU, removable media is booted before fixed media.

Version 1 (Vl.00) of the ROM code supports only English and

Spanish text. Switch positions 1 through 5 and 7 through 11 require the user to select the desired language.

Version 2 (V2.00) of the ROM code supports English, Spanish,

French, German, Dutch, Swedish, Italian, and Portuguese text.

Switch positions 8 through 11 require the user to select the desired language. Switch positions 8 through 11 are reserved for future languages.

To correctly display text for the various languages, the terminal used as the console terminal must have certain abilities.

For Vl.00 of the ROM code the terminal only needs to display standard ASCII for both English and Spanish text. Bit 7 for all input is stripped to zero.

For V2.00 of the ROM code, some languages require that the terminal have the multinational character set (MCS) available along with ASCII. The terminal should be set up so characters from o through 127(10) select ASCII and characters from 128(10) to

255(10) select MCS. Some languages use 8-bit input also.

Table 3-4 lists the terminal requirements for the various languages.

If a VT220 is used as the console terminal, it must be set to

VT220 mode to let it display MCS characters.

Bootstrap and diagnostic programs for a MicroPDP-l1j53 system reside in two read-only memories or erasable-programmable read-only memories (ROMs or EPROMs) on the KDJII-DA module. The programs (ROM code) test the CPU module and memory at power-up or restart, and boot user's software from various devices.

3.3.1 Automatic Boot Mode

After the system start-up self-test passes, the ROM code automatically tries to load and start (autoboot) a program from the user's disk or tape drive. If successful, the ROM code displays a message at the console terminal. Example 3-1 shows a message for a typical system bootstrap in automatic boot mode.

3.3.2 Console Mode

Console mode lets the user select a boot device, list available boot programs, run ROM resident tests, obtain a map of all memory and I/O page locations, and Wrap the console SLU to the second

SLU.

You can enter console mode in the following two ways.

1. Depending on the contents of native register (NRI (12:08>, console mode is entered after testing is complete. In console mode, the ROM code lets the user determine the execution sequence by entering keyboard commands through the console terminal.

2. You can also enter console mode by typing (CTRL/C> during testing or the boot .equence. In this case, the native register bits are ignored.

When console mode is entered, the ROM code displays the message shown in Example 3-5, and waits for the user to enter a command.

Boot Command The Boot command lets the user select a boot device. The command uses arguments and optional switches.

Arguments to the command specify the device name and unit number.

The device name is a two letter mnemonic that describes the device. An optional third letter specifies the controller. If the unit number is omitted, the program assumes unit zero.

You can enter the Boot command in the following two ways.

1. Type B<RETURN>. The system prompts for the device name and unit number, as shown in Example 3-8. Example 3-9 shows a successful boot message (using device DL2).

2. Type B<SPACE>, the device name and unit number, and <RETURN>.

Map Command displays the current ROM code version number, determines and displays the size of consecutive memory, identifies all memory in the system, and maps all locations in the I/O page.

Memory is mapped from location zero to the I/O page, in 1 kilobyte increments. Not every location is mapped because it takes too much time. The map routine tries to identify the size of each system memory and each memory's CSR address (if applicable). If two or more noncontiguous memories are present, ROM code displays their descriptions separated by a blank line.

NOTE

If two memories share some common addresses, or have CSRs with the same address, the map command does not work correctly.

After all memory is mapped, the ROM code waits for the user to press <RETURN>. The command then continues the map, displaying all responding I/O page addresses. The I/O page map addresses are

17760000 through 17777776. All responding CPU addresses are also listed with a short description.

There is no description for addresses that respond and are on the external bus, with the exception of memory CSR's, if present, and

Q-Bus devices DU, MU, and XH. The map only identifies DU (disk

MSCP controller) and MU (tape MSCP controller) at their standard addresses of 17772150/2 and 17774500/2. The map identifies XH at addresses 17774440/56 and 17774460/76.

During the I/O page portion of the map command, when the onboard line time clock CSR at address 17777546 is reached, the ROM code follows the LTC CSR printout with either BEVNT

=

0 or BEVNT

=

1.

This identifies whether the BEVNT signal is present on the Q-Bus

(1 indicates the signal is present and 0 indicates the signal is not present). The line time clock test does not fail if the BEVNT signal is not present.

When the ROM code detects a device at addresses 17774440--17774456 or 17774460--17774476 during the I/O page portion of the map command, it identifies that device as XH for an Ethernet controller. Then the ROM code reads and types the six byte station address starting at either 17774440 or 17774460. The ROM code prints out in hexadecimal bits 7:4 then 3:0 of each of the six bytes. The map command message in Example 3-11 shows one DEQNA present at location 17774440--17774456.

Test Command causes the ROM code to run most of the power-up tests in a continuous loop. The ROM code starts at test 3, runs all applicable tests and subtests, then restarts the loop after test 6 is complete. You can abort testing and restart console mode at any time by typing <CTRL/C>. If an error occurs, the test 3 through 6 error routine is entered. You can do one of the following two actions at this time.

• Restart console mode by typing <CTRL/C>.

• Loop through all of the tests, ignoring errors, by typing

L<RETURN>.

After exiting the test loop, the ROM code displays the total number of loops (passes) and the total number of errors (if any) in the following format. nnn/xxx n is the number of errors and x is the number of times the tests were attempted.

In Example 3-12 the Test command is entered to run all loopable tests. After four passes, the testing sequence is aborted with no errors.

Commands are Help, Boot, List, Map, Test, and Wrap.

Wrap Command -- takes all input from the console terminal (DLARTO) and sends it to the second SLU (DLART1), or a selected SLU. All input from DLARTl or the selected SLU is sent to the console terminal. This lets the user at DLARTO communicate with another system through DLARTl or another selected SLU. The command has one optional switch: IA.

Entering the Wrap command with the switch causes the ROM code to request an alternate SLU address. The valid alternate address range is 17776500 through 17776676.

Example 3-13 shows the Wrap command being entered without the switch. The console wraps to the second SLU at address 17776500.

3.4 TEST CODE ERROR MESSAGES

3.4.1 Test 1 Errors

When started, the ROM code runs a series of tests that verify the basic Memory Management Unit (MMU) operation and the ROM code. At this point in the testing sequence, the comprehensive error message display routines are disabled. If an error occurs during test 1, the ROM code displays the following error message.

KDJII-D/S 1.00

This message indicates that a fatal error condition occurred. The

ROM code ignores any keyboard input, except to display the error message each time input is received.

3.4.2 Test 2 Errors

This test checks the console SLU. When the SLUO test is running, the ROM code assumes that error messages cannot be displayed.

Therefore, if an error occurs, the ROM code loops on the error.

3.4.3 Test 3 through 6 Errors

These are the main CPU and memory tests. These are also the tests continuously looped when you use the Test command. If an error is detected during these tests, the ROM code displays a brief error message. All errors are treated as fatal errors. The user is expected to fix the problem before continuing. However, errors can be bypassed for troubleshooting.

3.4.4 Override Errors

To bypass an error, you must type one of two commands when the error message is displayed. The ROM code displays the KDJII-D/S prompt and waits for input. Table 3-6 lists the error override commands and results.

Table 3-6

Command

Error Override Commands

Results

<CTRL/O>4<RETURN> Overrides error and enters console mode.

L<RETURN> Restarts tests at test 2. Loops through tests ignoring errors. Type <CTRL/C> to exit loop.

CAUTION

System media should either be removed or write protected before you bypass an error.

4.4.3 RQDX3 Controller Module

The RQDX3 controller is a dual-height module that interfaces up to four logical drive units to the Q22-Bus. The RQDX3 is an intelligent controller with onboard microprocessors and Q-Bus block mode DMA data transfer capability in 16-, 18-, or 22-bit addressing mode.

The RQDX3 controller module plugs into any available slot on the

BA23 backplane, except slot one rows A--D (reserved for CPU module) and slots 2 and 3, rows C and D.

4-13

SYSTEM OPTIONS

4.4.3.1 Base Address -- The module base address is configured by installing jumpers W02, W04, was,

W09, and Wll, and removing jumpers WOl, W03, W06, W07, WOB, and WlO as shown in Figure 4-10.

Address bits 13--15 are always asserted high because they are jumpered permanently by hard-wire connections.

4.4.3.2 Starting Logical Unit Number (LUN) -- The starting LUN equals the binary number represented by jumpers W12 (LSB) through

W17 (MSB) multiplied by four. When jumpers W12 through W17 are removed (Figure 4-11), a starting LUN of zero is selected. See

Table 4-5 for typical examples.

CONFIGURATION 5

5.1 CONFIGURATION RULES

You must consider the following factors when configuring a system in a BA23-A enclosure.

• The module physical priority in the backplane

• The I/O panel expansion space occupied

• The power requirements

• The module CSR addresses and interrupt vectors

5.1.1 Module Physical Priority

The order in which options are placed in the backplane affects system performance. The following rules govern the configuration of a MicroPDP-ll/53 system.

• All MicroPDP-ll/53 Q-Bus options are installed below the CPU module, in slots 2 through 8.

NOTE

Expansion memory modules are installed in slots 2 and 3. No empty slots are allowed between the CPU and expansion memory modules.

•

• Quad-height options may be installed anywhere in slots 2 through 8.

• Dual-height options can be installed anywhere in slots 4 through 8 (rows AB or CD) and in slots 2 and 3 on the AB rows only. No dual-height options may be installed in slots 2 or 3 on the CD rows.

Dual-height options alone in slots 4 through 8 rows AB or CD, require an M9047 grant card next to them when followed by another module (quad or dual) in the next slot.

• The backplane can accommodate modules that total up to 22 ac loads.

• Loading loads.

(dc) of all modules in the system cannot exceed 20 dc

•

•

This chapter describes the following topics.

• Start-up self-test

Console on-line debugging technique (ODT) mode

Diskette or tape diagnostics

• BA23-A enclosure (troubleshooting)

6.2 START-UP SELF-TEST

The factory configuration of the KDJ1I-DA CPU module is set for diagnostic self-test and boot mode. This test runs each time the system is turned on or restarted, and tests the following modules.

CPU module (with on-board memory)

Expansion memory modules

The self-test begins by testing a small portion of the CPU module, then progressively tests more and more of the base system. The system enters automatic boot mode on successful completion of the start-up test (see Chapter 3 in this manual). If an error or failure is discovered during this self-test, an error message is displayed. Table 6-1 lists start-up self-test error codes and descriptions.

The three lines of the message are interpreted as follows (the fourth line is the KDJll-D/S prompt).

Line 1 -- KDJll-D/S is the CPU identifier and is the same in any error message. 4.62 is the test subtest. The test number

(4) is the same number that is in the native register

(NR<03:00» and displayed in the remote LEDs.

Line 2 -- This line is standard in any error message.

6.3 CONSOLE ODT MODE

Console ODT mode is entered in one of the following ways.

• The operator pressing the console terminal <BREAK> key, if halt-on-break jumper WII (on the CPU module) is not installed, or the halt-on-break switch is not disabled (on the console display panel printed circuit board).

NOTE

The break key must be enabled on the terminal also. For example, on a VT220 the break key can be disabled.

•

•

Execution of a Halt instruction in kernel mode, if halt option jumper WI (on the CPU module) is installed.

Q22-Bus BHALT line is asserted on the backplane.

6-4

DIAGNOSTICS

When the system has entered console ODT mode, it displays the following on the console terminal: nnnnnn

@

The number nnnnnn is the octal location of the next instruction to be executed, and the @ is the ODT prompt.

ODT consists of a group of commands and routines for finding error conditions, and for simple communication with the system. You can examine or modify the contents of the system's registers and memory locations by entering ODT commands. Table 6-2 describes ODT commands. See the Microcomputer and Memory Handbook (EB-18451-20) for a more detailed description.
