Charac- ters are transmitted to the LP05’s print buffer under program control via the M8027 interface module. The LPOS print buffer stores up to a 132-character line. Each print cycleis initiated by a terminating character. Terminating characters include carriage return (CR), line feed (LF), and form feed (FF). Printing requires two revolutions of the drum. Odd-numbered and even-numbered columns are printed during alternate revolutions of the drum. Circuitsin the LPO05 scan the print buffer characters stored for a linein synchronization with the rotating drum. Each characteris printed, as appropriate, by driving the hammer for those odd- or even-numbered columns in which a particular character appears. An inked mbbon and paper pass between the drum and the hammers, and thus the characters are printed. , | , Note that LPOS printers are avaflable with uppercase letters only (64chamcwr set) or upper- and lowercase letters (96 character sat) depending upon model. All madels are capable of printing numerals and punctuation marks. ci 1.2.3 LA180 DECprinter o e The LA180 DECprmter mcluded with LPV11- PA, -PB, -PC, and »PD »;,i,;cadelsis a free-standmg, pedestal-type impact printer thatiis capable of printing a maximum of 132 charactersper line. To initiate a print cycle, a line terminator character (LF, FF, or CR)is required. The printer contains a 256 by 8 character buffer which stores printable and nonuprmtable characters. This bufferis loaded characterby-character via the LPV11 interface under program control. After each characteris stored in the buffer, a read functionis performed to determine if the characteris a lineterminator character. Ifit is, the characters stored in thebuffer are printed; if it is not, the next characters are input until the complete lineis stored, as indicated when the line terminator characteris recewed and stored. Each characteris txt'ansferwjfE to the printer as a parallel 7-bit ASCII plus aptmnal parity code. The printer is a high-speed dot matrix printer that prints at speeds up to 180characters per second. It produces a hard copy original plus up to five duplicate copies on tractor-driven continuous forms, varying in width from 10.2 cm (4 in) to 37.8 cm (14-7/8 in). The average printing speeds are 70 lines per minute on full lines, and 300 lines per minute on short lines. The printer responds only to codes representing the LA 180 character set and six command characters. All other codes are ignored. Refer to the LA180 DECprinter manual supplied with the LPV11 option for detailed printer information. 1.3 SPECIFICATIONS 1.3.1 LPV11 Interface Module (M8027) The LPV11 interface module can be installed in any LSI-11 bus structured backplane. Standard device and interrupt vector addresses are factory configured. Non-standard addresses can be configured by the user by removing and/or installing jumpers on the module. A 40-pin connector (J1) allows the user to connect the module to the printer via an appropriate cable supplied with the LPV11 option (defined in Table 1-1).

Installation involves: 1. Installing the LPV11 interface module in the LSI-11 backplane 2. Installing the printer (connecting ac power and connecting to the LSMI system via an interface cable). Each interface moduleis shipped from the factory with jumpers j configured for standard (DEC software-compatible) device and interrupt vector assignments. It is nmmally not necessary for the user to configure address or vector jumpers unless special device and/or interrupt vectors are desired. They can be configured as directedin Paragraph 2.2. The factory (or user) confng red mmdule can beinstalled as directedin Paragraph 2.3. | CAUTION Modules must be installed or removed only when dc power is removed from the backplane. The remainder of this chapter contains specific instructions for configuring and installing the LPV11 interface module (check jumper configuration before installing module), and installing the printer (LPOS or LA180). Use only those procedures applicable to the specific option model (type of printer). 2.2 CONFIGURING INTERFACE MODULE JUMPERS 2.2.1 General LPV11 interface modulej umpers are located as shownin Figure 2-1. Factory-installedjumpers can be removed by carefully cutting each end close to the printed circuit board. Note that facmrywmstalled jumpers have W numbers assigned. Adjamm to each factory-installedjjumper location are wire-wrap pins allowing a user to reinstall a jumper prewously removed. The remaining jumpers (nm factory mstalled) can be installed usmg the desxgnatcd wire-wrap pins. Dotsin Figure 2-1 represent wire-wrap pins; a line connecting a pair of pins shows the electrical comnc«:tmn that must be wire-wrapped to insert thatjumper. Note Juper F+ (factory installed W6) and F- do not have associated wire-wrap pins. Thesejumpers must be installed by soldering and removed by cutting or unsoldering. 3 | - 3 = JUMPERS BROKEN I FOR CLARITY ON THIS FIGURE.

Do not configure the module with both F- and W6 installed. 23 LPV11 INTERFACE MODULE INSTALLATION 2.3.1 Device Priority LPV11 device prmmty must be first considered to determine which backplane slotin which the LPV11 module will be installed. In all LSI-11 systems, device priority is established by the relative electrical position of device interface modules along the I/O bus. H9270 and DRV11-B backplanes are struc- tured to allow the user to configure device priority by installing modulesin appropriate positions. The PDP-11/03 includes one factory-installed H9270 backplane. Figure 2-4 is a front view of the H9270 backplane, showing typical module locations. The processor module should be installed in backplane slots A1-D1. 2-4 VIEW FROM MODULE SIDE OF BACKPLANE A 8 c D PROCESSOR A ‘ - ) BLOCK ‘ ;‘ | CONNECTOR ) ‘ / ; OPTION 2 OPTION 1 OPTION 6 OPTION PREFERRED LOCATION FOR MMV11i~A CORE MEMORY.

These signals nmmally propagate through option modules until they reach the requesting device. Option 1, as shownin Figure 2-4, is the first device location to receive the damywhamed signals when the processor moduleis mstalledin slots A1-D1. Hence, six optmns can be installedin the baekplane The PDP-11/03is shipped with the processor moduleinstalled in the backplane as shown in the figure Do not relocate the processor module to another location; a separate non-bused (jumper) connection is provided on the backplane tothis lmcatmn for _ proper RUN indicator nperatmn CAUTION Do not configure the system with unused option loca tions in the backplane between theprocessor module and I/0 devices that require either of the two daisyained signals; an unused location will break the , daisymhmn signal continuity, and devices inhigher numbered locations will not receive interr ipt or DMA grant signals. Unused locations should occur only in the highest numbered option locations. Note that the daisy-chained BIAK and BDMG signals always follow in increasing numbered option locations, as shown in the figure. Device priority on the DDV11-B backplane is established in the same manner as described for the H9270 backplane. However, larger physical size allows up to 16 options (including a bus terminator module) to be installed on the backplane. Device (option) locations are shown in Figure 2-5. This highest priority locationis option 1; the lowest priority location is option 16. Since the LPV11 prmter system only functions as an output device, and if it is interrupted by higher priority devices thereis no danger of losing data, it can be located on the backplane as a low priority device. Install input devwes as the higher priority devices. Refer to the Microcomputer Handbook for system installation and bus termination details when the system contains MMV11-A core memory or more than six memory or peripheral device options. 2-5 VIEW FROM MODULE SIDE OF BACKPLANE PREFERRED LOCATION FOR PROCESSOR MODULE A 7~ r B N c D E F PROCESSOR 1 OPTION 2 OPTION 1 OPTION 3 OPTION 4 3 OPTION 6 OPTION & 4 TERMINAL { OPTION 7 OPTION 8 B BLOCK OPTION 10 OPTION 9 6 OPTION 11 OPTION 12 7 OPTION 14 OPTION 13 8 OPTION 15 OPTION 16 9 POWER ~ 2 USER DEFINED SLOTS MR - 0338 \Figurve 2-5 Typical DDVI 1-B Backplane '2.3.2 Module Installation - Modules must be installed or removed only when de power is removed from the backplane.

A summary of commands for both printers is provided in Table 3-1. The programmer must use the proper command to produce the desired result with a specific prmter All characters (pnntmg and non-printing) are 7~b1t ASCH plus optmnal parity.

These registers include the Line Printer Control and Status (LPCS) and Line Printer Data Buffer (LPDB). These registers are factory configured with LSI-11 bus addresses 177514 and 177516, respectively, and are softwaremcampatxble with DEC software. However, if additional LPV11 options are added to the system, or if the user requiresaddresses other than those factory configured, it will be nece&sary to alter interface modulejumpers as directedin Paragraph 2.2 and provide an LPV11 program using these specml device addresses. Each reglster is subscquently descmbedin Tables 3-2 and 3-3 and both are shownin Flgure 3-1. ‘Table 3-2 LPCS Register Bit Functions Bit Name Function 15 ERROR Asserted (1) whenever an error condition extsts in the line printer.

When the LPCS register INTERRUPT ENABLE bitis set and either the DONE orERROR bitis set, an interrupt requestis initiated. Entry to the LPV11 service routine is normally viathe factoryuconfigured vector addresses 200(PC) and 202 (PS). When servicing an interrupt and a second interrupt occurs, the second (and subsequent)interrupt maynot be remgmzed This condition can be avoided by checking for both interrupt conditions (DONE and ERROR)in the mtcrrupt service routine. 3.1.4 Printer Operation LP0S - Characters are sequentially output to the printer one character at a time, under program control. All characters are output via the LPV11 interface module LPDB register. Characters are storedin the LPOS print buffer until one of three special non»-prmtmg characters (CR, PF, or FF)is recognized. When a special characmris recognized, the print cycle starts and the wmplew lineis printed. LA180 - Characters are sequentially output to the printer and stored in the same manner as for the LPOS printer. When a special character [CR, LF (same ASCII code as the LPO5 PF character), or FF] is recognized, all characters comprising the line are sequentially printed. 3.2 PROGRAMMING EXAMPLE A programming example for use with any LPV11 model is as shown. Portions shown include the LPV11 vector locations [(200 and 202), one instruction in the main program that enables LPV11 interrupts, and the LPV11 interrupt service routine.

Each logic functionis briefly describedin the followmg paragraphs Detailed information can be obtained by referring to drawmg CS-M8027 (includedin the print set supplied with the optmn) and the LA180 and LPO5 strobc timing diagrams (Flgures 4-2 and 4-3, respectively). 4.2 4.2.1 LPV1l INTERFACE FUNCTIONS|) General | | LPV11 interface functions for use with LPO5 or LA 180 printers are similar; however, printer strobe signals required by the printer in use are different. By using the specified mterface cable for the printer in use, the interface module produces the appropnate prmter strobe. The major part of the LSI-11 bus 1 /O and mterrupt pmmcolis performed by two speclal integrated circuits (DC004 and DCO003, respectively). These integrated circuit functions are describedin the 197778 Microcomputer Handboak (Second Edition), Appendnx F. Refer to drawing CS-M8027 to obtain correct signal names. LPV11 programmed 1/0O and interrupt transactions are as describedin the Microcomputer Handbook, Section 1, Chapter 3. 4.2.2 Bus Transceivers and Drivers Bus transceivers (DEC 8641) receive the LSI-11 bus BDAL<0:7> L signals and distribute the bits on DAL<O0:7> H lines. In addition, they transmit LPCS bits or interrupt vector address bits during a DATI bus cycle, or interrupt sequence. Bus drivers (DEC 8881) transmit LPCS bits 8 and 15 during a DATI bus cyclein which the LPCSis addressed. | 4.2.3 Device Address Decoding Device address decoding logic receives DAL<2:7> H, BDAL<8:12> L, and BBS7 signals and compares the address to the device addressjumpers (Paragraph 2.2.1); when the LSI-11 bus address bits 2 through 15 equal the jumper-configured address for the LPV11, ENB H goes active. Note that address bits 13, 14, and 15 are not decoded by the LPV11; the LSI-11 processor asserts BBS7 when these bits are all logtcal ls, md:catmg an addressis pmmnt in bank 7. In addition, address bits <0:2> are decoded for the device register (and byte) in the bus control logic. Bus control logic programmed transfer functions are enabled by the active ENB H signal. 4.2.4 Print Data Transmission Print datais transmitted to the printer from the LSI-11 bus under program control. The print charac- ter buffer functions as the LPDB register. Itis an 8-bit register, including the optional Pamy /D8 bit. The bus control logic produces WRITE DB H during a DATO or DATOB bus cyclein which the LPDBis addressed. Jumper W8 can be removed to disable program transfer of LPDB bit 07 to the printer. When W8is removed, P DATA 8 is forced low; if desired, jumper Pcan be installed to force P DATA 8 high. | 4-1 Uppercase translation logic gives the user the option to print upper/lowercase data files on an uppercase letters-only printer (LP05-VA, VB, VC, or VD). Software overhead is reduced by performing the lowercase to uppercase translation in hardware, rather than in software. Jumper W7 normally applies unmodified upper/lowercase ASCII characters to the print character buffer. When the lower- case to uppercase letters translation is desired, jumper W7 is removed and jumper T is installed. The _fi_lesgllt 248 }hat ASCII codes 140 through 177 are translated to 100 through 137 (bit 5 = 0), as shown in ~Table 4-1. 4.2.5 Read Data Select Logic 4.2.6 Ready Flag and LP Strobe Logic Read data select logic functions enable the LSI-11 processor to read the LPCS register under program control or the LPV11s interrupt vector during an interrupt transaction. Control signals READ CS H and VECTOR H select the bits. LPCS bits are produced by various LPV11 interface functions as shown on Figure 4-1. Vector address bits are jumper-selected as described in Paragraph 2.2.2. ~ Ready flag (LPCS bit 7) and line printer (LP) strobe logic provides the proper control signal interface to the printer. The LP strobe function is used only for LPOS printers; the LA180 uses the DATA STROBE H signal generated by the bus control logic. Selection of the appropriate strobe source is automatically produced by the LA /LP select logic function. Connecting the proper interface cable for the LA 180 grounds the SELECT line, causing the LA /LP select logic to select LA180 (data selector port B) functions. When the LPOS is used, the interface cable does not ground the line and LPOS (data selector port A) functions are selected. The LA 180 strobe is a negative-going pulse. The LPOS strobe is a positive-going pulse initiated by the leading edge of P DEMAND H and cleared by the trailing edge of P DEMAND H. | | The ready flag is produced by the logic function when the printer is requesting a character (P DEMAND H goes active) and no error is present. In addition to setting the LPCS ready flag, the RQST A - signal input to the interrupt logic goes active; if interrupts are enabled (LPCS bit 6 is set), an interrupt request is initiated (BIRQ L goes active). The ready flag is cleared by an active DATA STROBE L - signal when writing a new character into the print character buffer. | When an error condition occurs in the printer, the printer asserts P FAULT L. The fault is applied to the error flip-flop logic (via the M FAULT H signal), producing an active ERROR L signal and an active ERROR H signal (LPCS bit 15). The ready flag logic function responds by not producing a - ready flag, although P DEMAND H may be active, and by producing an active RQST A H signal. Thus, an error condition will initiate an interrupt request (if LPCS bit 6 is set) and set LPCS bit 15. The error flag is cleared by the processor reading the LPCS register if the ready flag is not set, or when the LPV11s interrupt vector is read. 4.2.7 Error Filter | | | | | The error filter is always used (automatically selected) for use with the LA180 printer and jumper selected for optional use with the LPOS printer. This function is produced by a clock pulse gener~ ator/counter circuit that requires an active P FAULT L signal for 8 ms before the M FAULT H signal is produced. The minimum time requirement for the fault signal presence prevents false errors due to noise. 4.2.8 | BRPLY Delay Bus control logic generation of BRPLY L signals is delayed 400 ns (approximately) by factory-in- stalled jumper W1. W1 connects C3 to the DC004 RxCx input pin, delaying the BRPLY L signal for proper operation with LA 180 printers. When LPO5 printers are used, the jumper may be either left installed or removed to reduce the BRPLY delay, as desired. | | 4.2.9 Initialization | | | | | The LSI-11 processor initializes devices on the LSI-11 bus by asserting BINIT L. BINIT L is received by the interrupt logic and distributed as the INIT L signal. INIT L clears the print character buffer, error flip-flop logic, interrupt enable bit (LPCS bit 6), and sets the ready flag. 4-2 — ) +5V DEVICE " | : | /\ . | , BBS7 ADDRESS JUMPERS , - ENB H L »| _ BDAL <8122 L W7 .

Maintenance procedures for the printers (LPOS5 or LA180) are covered in the appropriate printer manuals supplied with the option and are not repeated in this manual. As a general rule, the user should first check that the LPV 11 interface module is properly installed as described in Chapter 2 and that printer controls are properly set for operation. If the module appears to be properly installed (jumpers are properly configured, interface cable is properly installed, no unused option locations in the backplane between the LPV11 and the LSI-11 processor module), confirm the operational status of the interface module by executing the diagnostic software supplied with the option. Printer controls are described in printer documents supplied with the LPV11 option. 5.2 DIAGNOSTIC SOFTWARE The LPV11 option includes diagnostic software in the ZJ178-RB LP11/LP05 Documentation/Paper Tape Kit. Documentation includes diagnostic program listings and detailed operating instructions. The diagnostic program can be input using the binary paper tape included in the kit. Running the program will effectively test the LPV11 printer system, including interface module functions and printer functions. Minimum hardware requirements for running this diagnostic include the basic LSI-11 system, including 4K read/write memory in Bank 0, a console terminal, and a paper tape reader. Refer to the Microcomputer Handbook, Section 1, Paragraph 9.3 for general instructions for using paper tape diagnostics. 3.3 DIGITAL SERVICES Maintenance services can be performed by the user or by DIGITAL, as desired. DIGITAL’s services are described in the Microcomputer Handbook, Section 5, Chapter 3. gy Reader’s Comments LPV11 PRINTER SYSTEM P, , USER’S MANUAL EK-LPV11-0OP-001 Your comments and suggestions will help us in our continuous effort to improve the quality and usefulness of our publications.
