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. XON/XOFF and DTR are supported

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 3.3, Placing the PQ-6 PLUS (RO) into Operation, details

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

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) 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

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 contacti

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 AN
