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.

ELECTION
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.

EQUEST
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.
