Operators
AUXILIARY Connector-Provides connections for
an
X-Y
Plotter
and
an
External Clock input (see Controls, Con-
nectors,
and
Indicators).
GPIB
Connector-Provides
the ANSI/IEEE Std 488-1978
compatible electrical and mechanical connection to the
GPIB. The connector is only
on
instruments with Option
10. The function
of
each pin
of
the connector is shown
in
Table 7-5.
GPIB PARAMETERS
Switch-Allows
the selection
of
setup options for the GPIB interface. The switch is read
at power-up
and
when interface clear messages are
received.
Five
sections
of
the switch select the GPIB
address, one selects the terminator, two select
talk/listen modes, and two are used for printer/plotter
selection. The function
of
each switch section is shown
in
Table 7-6.

Switches 9 and
10
select printer/plotter devices at power-up.
The devices
may
be changed after power-up using Option
commands,
or
in
the case
of
the 2230, the
MENU
controls. Two
EPSON@
formats are selectable. EPS7 uses seven print wires
per head pass,
and
is
usually slower. It
is
the chr$(27) "L"
mode.
EPSS
uses eight print wires per head pass, and
is
usu-
ally the faster print-head speed. It
is
the chr$(27) "Y" mode.
In
this mode, most Epson and Epson-compatible printers
will
not
strike any print wire more often than every second pixel.
EPSS
is
selected when parity
is
disabled.
Printing/plotting devices are selected
with
the following switch
positions:
