3. Send that command to the

printer (press the Print Screen
Button or print the
document/file that contains the
Host/PC download command).
The self-test will print out in a
few seconds.

Follow the steps below to start the

self-test by setting the configuration
switches.

1. Verify that the printer is

connected properly to the 
PQ-8.

2. Power off the printer interface. 

3. Set configuration switch SW1:8

(far right on the first switch
bank) to “|”.  Verify that
configuration switches SW1:1
through SW1:3 are not all set to
“|”, but are set to a valid Twinax
Address.

4. Power on the PQ-8. A self-test

will print within a few seconds
after power up. After the self-test
prints, the LED lights “Host
Ready” and “Printer Ready” will
begin blinking, indicating that
the PQ-8 is not in operating
mode.

5. Power off the PQ-8 and return

configuration switch SW1:8 to
the “o” position.

Two self-test pages will print if the

PQ-8 is installed properly. Sample
printouts are shown beginning on
page 17. The selections shown in 
the samples are factory defaults. 
The numbers at the left margin are
command numbers used to change
this setting using Host/PC download
commands (see Section 4.3).

If the test does not print, the 

PQ-8 failed the self-test. Call for
technical support.

The PQ-8 can be set up to print the
buffer in hexadecimal EBCDIC
code. This can be useful for a
technician to diagnose problems
with the PQ-8 or the printer.

The EBCDIC hex data is printed

on a grid corresponding to the
data’s position in the buffer. If the
hex data represents a printable
character, that character is printed
below the hex data.

To start the EBCDIC Hex Dump

through Host/PC Download:

1. Verify that the printer is

connected properly to the 
PQ-8.

2. Type “&%Z42,1” on the screen.
