Section 3 Command Descriptions

3.11

Data EOI Ln

The Data EOI command specifies how the IEEE 488

EOI

line will be used

when the Serial488/4 sends serial port data to the addressed listener, usually the bus

controller, for the selected serial port. The Port Select command (

) is used to

select the serial port regardless of addressing mode in use. In the

mode, the

EOI

line is asserted by the Serial488/4 when the data byte matches the selected serial

terminator (

Txxx

). In the

mode the

EOI

line is not used. If the

mode is

selected, the

EOI

line is asserted when the last serial input character is sent over the

IEEE bus. In the

mode the

EOI

line is asserted on either a match with the serial

terminator or the last serial character sent. The factory default setting as set by the

Save Configuration command (

) is

EOI

is disabled.

Assert

EOI

on serial terminator character.

L1 EOI

is disabled.

Assert

EOI

on last serial input character.

Assert

EOI

on serial terminator character or last serial character.

Returns last Data EOI command selected.

Example 1: Select

EOI

on serial terminator using dual primary addressing mode.

PRINT#1,"OUTPUT08;P1X" select port 1 as the current port

PRINT#1,"OUTPUT08;L0X"

select data

EOI

on serial terminator

Example 2: Disable

EOI

on selected port using secondary addressing mode.

PRINT#1,"OUTPUT0800;p1L1X"

disable

EOI

on port 1
