PQ-6 PLUS (RO)
2.1 Application
2. Introduction
The PQ-6 PLUS (RO) is a “receive-only” microprocessor-based printer interface for the IBM System/34,
System/36, and System/38 computers. It allows a printer with an RS-232 or Centronics compatible port to
interface with IBM twinaxial cable via a male DB15 and twinax “pigtail” cable. Device address and serial or
parallel output are switch selectable, and the baud rate is selectable in 16 settings from 50 to 19,200 bps.
XON/XOFF and DTR are supported by the PQ-6 PLUS (RO) for buffer control. Data format is 7 bits, space
parity, 1 stop or 8 data bits, no parity, 1 stop bit.
2.2 Description
Data and commands are received from the twinax cable serially (1-MHz clock) by the proprietary front-end
processor of the PQ-6 PLUS (RO). Those commands and data addressed to the PQ-6 PLUS (RO) as
determined by the device address selection switches, are passed to the Z-80A microprocessor for further
processing. The Z-80A CPU converts EBCDIC to ASCII and makes the protocol conversions it needs to change
the high-speed synchronous twinax input into an asynchronous RS-232 ASCII output or Centronics compatible
output. You may bypass the EBCDIC to ASCII controller to the printer using the PQ-6 PLUS (RO) command-
passthrough feature (see Section 4.3).
Input data from the controlling host consists of data and command sequences normally interpreted by an
IBM 5256, 5224, and 5225 printer. In addition to printable characters and carriage-control characters (such as
new line, carriage return, and line feed), the controlling host can send command sequences to control output
format. These commands include page width, page length, characters-per-inch, and horizontal and vertical
carriage-positioning sequences. The PQ-6 PLUS (RO) interprets these command sequences and outputs ASCII
characters to perform the appropriate function. For example, when a form length command is received, the
value is stored internally in the PQ-6 PLUS (RO); when it receives a request for a form feed or for an absolute
move to line one of the next page, the PQ-6 PLUS (RO) will cause the paper in the attached printer to eject a
form of the previously specified form length. Since some commands issued to IBM printers cannot be easily
implemented on RS-232 ASCII printers, these commands are interpreted by the PQ-6 PLUS (RO) and
discarded. For example, a command to set the lines per inch to seventy-two is accepted by the PQ-6 PLUS
(RO), but no corresponding ASCII sequence is output, since the PQ-6 PLUS (RO) cannot know in advance
whether the attached printer can accommodate such a command and how to implement it.
As shipped from the factory, the PQ-6 PLUS (RO) is configured to emulate an IBM 5256 printer. If the PQ-6
PLUS (RO) is to emulate the 5224 or 5225 printer, you need to set the appropriate switch on the printed circuit
board (see Section 4.5).
Serial transmission speed is switch-selectable via printed-circuit-board switches, up to 19,200 bps. Output data
is asynchronous with one start bit, seven data bits, space parity, and one stop bit.
The PQ-6 PLUS (RO) supports both software flow control via XON/XOFF characters and hardware flow
control via the DTR RS-232 input lead. The PQ-6 PLUS (RO) will suspend printing whenever the DTR signal
drops and will resume printing when DTR is asserted. Similarly, when it receives an XOFF character (hex 13),
the PQ-6 PLUS (RO) suspends printing; when it receives an XON (hex 11), it will resume printing. Both
methods are always enabled. No configuration is required.

PQ-6 PLUS (RO)
The Centronics parallel interface is a 25-pin, parallel byte interface. It has eight lines that carry their
respective binary bits in parallel. The transmission of these data bits is controlled by the computer-supplied
STROBE pulse. Handshaking (flow control) is achieved by asserting or deasserting either the ACKNLG or
BUSY signal from the printer.

3. Installation
The installation procedure is divided into three sections:
• Section 3.1, Initial Setup, explains how to position the PQ-6 (RO) after unpacking it, plug in the power
supply, and run off-line tests.
• Section 3.2, System Configuration and Connection, covers the considerations for setting up the PQ-6 PLUS
(RO). Items covered include setting the device address and all corresponding physical connections.
• Section 3.3, Placing the PQ-6 PLUS (RO) into Operation, details online testing procedures that you should
implement after completely installing the unit. This section also contains recovery procedures that you can
use if the PQ-6 PLUS (RO) malfunctions.

Self-Test
After running the power test successfully, you can run the self-test to check the PQ-6 PLUS (RO) program
memory (ROM) and buffer memory (RAM). You can perform the self-test via two different methods: internal
DIP switches or the front-panel test button. Either way, the printer will print the software revision level, address
selected, and printer emulated. The self-test will also send a printed barber-pole test pattern to the printer. The
amount of data in the barber pole is different between the two types of self-tests. The self-test procedures and
device response are shown in Table 3-5. Figure 3-1 illustrates a sample of a self-test printout.

PQ-6 PLUS (RO)
3.2 System Configuration and Connection
At this point, the PQ-6 PLUS (RO)’s serial or parallel port has been tested off-line and verified to be in working
condition. However, before attaching to the host system, you must consider the overall system layout to establish
the relative device positioning, port selection, cabling, device addressing, and unit identification.
3.2.1 PQ-6 PLUS (RO) ADDRESS SELECTION
Determine the correct device address number for the PQ-6 to use by contacting the person responsible for
assigning workstation and device addresses.
Locate the printer-options/address-selection DIP switches by removing the top half of the enclosure. The
switches are labeled SW2: ADR4 (POS 6), ADR2 (POS 7), and ADR1 (POS 8).
Set the three switches on the right of the DIP switch to arrive at the proper twinax address. When the switch
is OFF, it represents a zero. Conversely, when the switch is ON, it represents a one. The three switches are
labeled ADR 4, 2, and 1, representing a binary value. Therefore, any address, zero to six, can be represented by
an appropriate on-off configuration of the switches. Examples are given in Table 3-6.

3.2.2 SYSTEM CONFIGURATION REQUEST
Physically, the PQ-6 PLUS (RO) is now properly addressed and cabled to the host system or remote controller.
However, before the System 3X or AS/400 system will recognize the PQ-6 PLUS (RO), you must: 1) make sure
the PQ-6 PLUS (RO) is emulating the proper system device and 2) perform a system configuration (unless the
PQ-6 PLUS (RO) is replacing an existing printer or you have auto-config enabled).
As shipped from the factory, the PQ-6 PLUS (RO) is configured to emulate an IBM 5256 printer. On the
inside of the PQ-6 PLUS (RO) are two DIP switches labeled ID1 and ID2 SW2, positions 1 and 2. They select
the IBM printer to be emulated (5256, 5224, or 5225). Table 3-7 gives the proper settings for selecting the
desired printer type.

PQ-6 PLUS (RO)
You must configure the system at a console to inform the operating system of the new device port, address,
and unit ID assignments.
NOTE
You don’t have to configure the system if a previously existing 5256, 5224, or 5225
printer was replaced by the PQ-6 PLUS (RO) or if you have auto-config enabled on the
AS/400. If the PQ-6 PLUS (RO) is replacing an existing device, printer ID and device
addressing must remain as established for the removed device.
3.2.3 PRINTER CODES FOR PITCH AND DENSITY
The printer control ode feature in the PQ-6 PLUS (RO) allows the host to control the horizontal pitch (10 and
15 CPI) and vertical pitch (6 and 8 LPI) for certain attached ASCII printers. You can find the list of printers on
page 20.
3.3 Placing the PQ-6 in Operation
When notified that the system operator has completed the system configuration, you can power on the PQ-6
PLUS (RO) (and all other cabled-through devices) using the following procedure:
A. Plug the power supply into the AC line.
B. Place the AC power switch on the attached printer in the “ON” position and place the printer into
“on-line” mode. The DTR indicator should light.
C. The LINE SYNC indicator should light as soon as communications with the host are established. The PQ-6
PLUS (RO) should now be exercised online to verify the operational readiness. Simply execute a print
comand.

4.1.1 FUNCTION SWITCHES
• Test: Pressing this switch will cause the TEST light to blink and a test pattern to be printed. If the PQ-6
(RO) cannot detect the attached printer, the TEST light will blink repeatedly. You can clear this condition
by readying the printer.
• Line Feed: Pressing the LINE FEED switch will cause the paper to advance one line for each key you press.
The internal line counter will also be advanced. For continuous line feeds, hold this switch “ON.”
• Form Feed: Pressing the FORM FEED switch will cause the paper to move to the top of the next form.
• Stop: Pressing the STOP switch stops printing on the PQ-6 PLUS (RO) Plus. It also presents “unit not
available” status to the controller. The message “press start on printer Pn” will appear on the controlling
console.
• Start: Pressing the START switch will present “unit available” status to the controller and clear the STOP
message. Printing will resume on the PQ-6 Plus.
• Reset: Pressing the RESET switch (located on the rear panel) initializes all PQ-6 PLUS (RO) hardware.

4.1.2 INDICATOR LIGHTS
• Power: Indicates that AC power has been applied to the unit.
• Line Sync: Indicates that the PQ-6 is responding to host polls.
• DTR (Data Terminal Ready): This signal from the printer to the PQ-6 PLUS (RO) indicates that the printer
is ready. This signal must be present for printing to proceed. You can enable flow control from the PQ-6
PLUS (RO) to the printer via XON/XOFF characters (Hex 11/Hex 13) or by dropping DTR when the
printer is not able to accept more data. When used as a Centronics port, the DTR light indicates select from
the printer.
• Data Out: Shows the data sent to the printer from the PQ-6 PLUS.
• Test: Blinks to indicates that internal tests are running. Blinks repeatedly if the select signal from the printer
is not present.
NOTE
Initial setup of internal switch and jumper settings for baud rate, printer interface, etc.,
must have been done previously. See Section 3.1.
4.2 Setup Mode
You can configure the PQ-6’s twinax address, printer emulated, ASCII printer type, page select and command
pass-through by the front panel or the internal DIP switches.
NOTE
ASCII printer type is only selectable via the front panel.
To enable configuration via the front panel, set the internal DIP switch bank 2 position 4 to OFF. The
factory-default setting for this switch position is ON.
To place the PQ-6 PLUS (RO) in setup mode, press and hold in the test switch while pressing and releasing the
reset switch, then release the test switch. The PQ-6 PLUS (RO) will print the following menu on the attached
printer:

SELECTING SWITCH SETTINGS
This mode lets you change the initial switch settings using the front panel instead of removing the top cover of
the PQ-6 PLUS.
Follow the instructions on the printed menu to select the different switch selections.
Upon exiting this mode, the switch selections will be stored in nonvolatile memory; the PQ-6 will retain
them until you change them using the front panel. On the next power-up, the PQ-6 PLUS will be configured to
the last stored setup. If no previous configuration was stored, the PQ-6 PLUS will default to the current switch
settings on the PC board, and the printer type will be Generic 3400h.
20
PQ-6 PLUS (RO)
When selecting printer type, the following data is used by the PQ-6 PLUS:
6 LPI
8 LPI
10 CPI
15 CPI
If you select a generic printer, the data used is located at 3400H and must be entered in the EPROM (see
Section 3.3.3).
To cancel a print job sent from the host, press and hold the STOP button on the PQ-6 Plus (RO) front
panel, and press the START button simultaneously. This sends a cancel request to the host, ending the print
job.
4.3 Command Pass-Through
The command pass-through feature in the PQ-6 PLUS (RO) lets you (or a programmer) control an attached
printer so that you can use special functions or features of the printer. It’s required because the IBM System 3X
operating software will not allow codes below Hex 40 to be transmitted on the twinax cable.
The method will transmit any 8-bit binary value from Hex 00 to Hex FF. The PQ-6 does not interpret or
translate data when in command pass-through mode.
To enter command pass-through mode, send the two-character sequence ampersand percent (&%) as part
of the normal printable data.
NOTE
Ampersand (&)=EBCDIC 50 Hex
Percent (%)=EBCDIC 6C Hex
After it enters command pass through mode, the PQ-6 PLUS (RO) takes characters from its internal print
buffer and outputs a single 8-bit binary value for every two EBCDIC characters it receives. The two EBCDIC
characters should embody the Hex representation of a legal 8-bit value.
Example: To send an ASCII escape character (1B Hex), send the two-character sequence ampersand percent
as a terminating character pair.
NOTE
No gaps or spaces should occur between any characters during command pass
through mode.
To send the sequence of ASCII characters “ABC (space) 1 2 3,” the following command pass-through
sequence would be sent:
EBCDIC - & % 4 1 4 2 4 3 2 0 3 1 3 2 3 3 & %
Hex
- 50 6C F4 F1 F4 F2 F4 F3 F2 F0 F3 F1 F3 F2 F3 F3 50 6C
21
PQ-6 PLUS (RO)
4.4 Buffer Print Mode
A buffer print listing interprets the actions of a printer or similar device on the twinax cable. All the data that is
received is listed as a hexadecimal printout. None of the formatting commands are executed; rather, they are
printed to aid in the interpretation.
4.4.1 PRINTOUT FORMAT
The data transmitted on the twinax cable is sent in blocks. A block can be one byte to 256 bytes long. The PQ-6
does not interpret the poll requests and device commands (such as device status) in a buffer print listing, but
prints all of the data received in each of the blocks, grouped in its block. Each byte that the PQ-6 receives is
expanded into three characters. The first two characters are the hexadecimal representation of the data byte,
and the third is the printable character that the byte would print if any. The three characters that are printed
for the received byte are printed in a vertical line. The most significant nibble on the second line, and the
printable character, if any, appear on the third line.
Characters are printed in groups of three lines, each line containing up to 128 characters. Since each block
of data can be up to 256 bytes, the blocks are printed in one or two groups of three lines. At the beginning of
each block of data, a new group of three lines starts. Thus, the position of the data within each block can be
readily seen.
Take care here if you’re using a printer that will print only 80 character lines. The groups of three lines are
up to 128 characters long. If the printer used will only print 80 character lines, or has been set to print only 80
character lines, one of two things will occur depending on the printer. If the printer is set to not auto-new-line,
the printer does an auto-new-line after reaching its line length, and the end of each line will be interlaced
between each of the original lines. You can interpret this once you realize what is happening.
4.4.2 DATA INTERPRETATION
The data is received in IBM EBCDIC. The format commands, while almost exactly the same for all twinax
systems, may be somewhat different. It is always best to consult the IBM manual for the particular system.
Listed next is a representation of the buffer printout. This particular listing was copied from a printout for
the beginning of the System 34 printer diagnostic. A few comments follow that will assist in its interpretation.

4.4.3 NOTES
The first block contains a single byte (a hex 0C). In EBCDIC, that’s a formfeed. Note that it is not a printing
character and the space under the 0C is blank. The next block of data contains 28 bytes. It starts with a 2B,
which is a format command (similar to an ASCII escape sequence). The 2BC6 denotes set line density, 02 says 2
bytes after the 2BC6 are part of the command. The 0C designates 6 lines per inch. The C6 has an “F” under it.
If it occurred not in a format command, it would be printable “F,” but it does not print since it is part of a
command.
The 2B D2 04 29 00 0A is the format command to set the printer into 10 characters per inch.
The 2B D1 03 81 00 sets the printer into the international character set.
The 2B C1 is for setting the maximum print position. 02 again states that 2 bytes follow the 2BC1 command,
and 84 is hex for 132. Thus, it sets the maximum print position to 132.
The 2B C2 sets the maximum number of print lines per page. 02 42 specifies two following bytes and sets it
to 66 lines per page.
The 2B C8 states what the printer will do when it receives a character that is undefined. This sequence of 02
bytes sets the printer to print a hex 40 (which is a space), and the 01 indicates to continue without any error
action.
The next block of data is actual EBCDIC printable data (the first data that the printer actually prints). This
pattern is the alphabet and numbers.
