3110 HELP FILES – SECTION 9

NOTE: 

GPIO controls, including 

GPIO Trigger and GPIO Output, 
are not supported on DSR Series 
systems.

The GPIO Setup checkboxes are 

used to configure the usage of 

the 3110’s three dedicated GPIO 
ports.

These ports can be accessed 
using the 3110’s DB-15 connector 
using pins 7 and 14 (referenced 

to ground on pin 13), and the 

DB-9 connector using pin 6 (ref-

erenced to ground on pin 3). See 

Figure 9.3

.

IMPORTANT: 

The GPIO pins are 

GPIO Setup

tied directly to the microprocessor and are not 
isolated. Take care not to exceed maximum 
ratings as permanent damage can occur. We 
highly recommend optical isolation (opto-cou-

pler, solid state relay, etc.) be used on all GPIO 

pins before connecting to external equipment.

Each GPIO port can be configured as an Input 

or an Output.

GPIO Input: 

When a GPIO port is configured 

as an input, it can be used in a GPIO Trig-
ger segment. When a GPIO Trigger segment 
is reached in a test sequence, the 3110 will 

pause and wait for the specified signal to be 

received on the designated GPIO port. When 
the signal is received, the test sequence will 
continue with the next segment following the 
trigger. NOTE: Only one GPIO port should be 

configured as an Input for use as a Trigger.

The electrical characteristics of a GPIO port 
when programmed as an input:

Voltage: Logic 0 = 0VDC; Logic 1 = 3.3VDC

Impedance: =>10 Mohm

GPIO Output: 

When a GPIO port is configured as 

an output, it can be used in a GPIO Output seg-
ment. See the Help topic 

“GPIO Output Control” 

for information on GPIO Output properties.

After assigning the pins as required for your 
use or application, press the Save button to 
save the settings. and then use the corre-
sponding pins to program a GPIO Trigger or 
GPIO Output segment. For more information 
about GPIO triggers and output segments, see 
the topics 

“Trigger Control”

 

or 

“GPIO Output 

Control” 

in the 

“Waveforms and Controls” 

section.
