PQ-6 PLUS (RO) 1. Specifications Controls—PCA35A-R3, PCA35AE-R2: Reset, Start, Stop, LF, FF, Test Speed—Serial port, 50 bps to 19.2 kbps Interface—IBM twinaxial; RS-232/V.
PQ-6 PLUS (RO) 2. Introduction 2.1 Application 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.
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.
PQ-6 PLUS (RO) 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.

PQ-6 PLUS (RO) Installing an RS-232 Printer Connect the 6-pin connector from the power supply to the 6-pin connector on the back of the PQ-6 PLUS (RO). Remove the top cover of the PQ-6 PLUS (RO). Do not plug it into the AC outlet at this time. Locate switch SW1 to set the baud rate and port configuration. Select the serial transmission speed (baud rate) for the PQ-6 PLUS (RO) output port using the four switches labeled Rate 4, Rate 3, Rate 2, and Rate 1 on the printed circuit board according to Table 3-1.
PQ-6 PLUS (RO) Installing a Centronics compatible printer Connect the 6-pin connector from the power supply to the 6-pin connector on the back of the PQ-6 PLUS (RO). Do not plug it into the AC outlet at this time. Place the large jumper strip at P3, in the “A-B” position for parallel output. The Centronics DB25 pinout is a standard DB25 to Centronics cable (Black Box part number EYN600) that connects the PC to the printer. This cable’s pinning is shown in Table 3-3. Table 3-3.
PQ-6 PLUS (RO) 3.1.3 OFF-LINE TEST OF PQ-6 PLUS (RO) AND PRINTER Initial Power On Test Once both the printer and the PQ-6 PLUS (RO) are plugged into the AC line, turn the printer power switch “ON” and put it into an “on-line” condition. Make sure the connection between the printer and the PQ-6 PLUS (RO) is complete. Run the following test to check the power and connections for both devices. Table 3-4. Initial Test.
PQ-6 PLUS (RO) 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.

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.
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.
PQ-6 PLUS (RO) No indicator lights Power supply not plugged into AC or into PQ-6. Plug power supply cord into a suitable receptacle. Line Sync light “OFF” Printer improperly addressed. Set correct address on SW2-6, 7, and 8; press RESET. Check twinax connections. DTR Flashing Attached printer OFF, in error condition, or switches and P2 jumper not in proper position. Turn on attached printer or check for proper configuration. Head moving printing No ribbon. Defective ribbon. Install new ribbon.

START TEST STOP LF FF TEST DATA OUT DTR LINE SYNC PWR Figure 4-1. Front-Panel Controls and Indicators. 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.
PQ-6 PLUS (RO) 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.

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.
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.
PQ-6 PLUS (RO) 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.
