9 – GPI Port
A 9-pin, female DB9 connector provides a 2-in/2-out GPI Gen-
eral Purpose Interface (GPI). For specifications, wiring diagrams
and pinouts, see Chapter 30, “GPI Port Reference.”
GPI Applications
GPI inputs can be connected to the outputs of a variety of switch-
ing devices such as footswitches, momentary or latching
push-button switches, or to the logic outputs of a larger show con-
trol system. Example applications of GPI inputs include remote
toggling of an S3 control surface function such as Talkback, mut-
ing a channel, or recalling a specific snapshot.
GPI outputs connect to compatible inputs found on a variety of
external devices such as LEDs, small relays, power sequencers,
and logic inputs on show control systems.
Example applications of GPI outputs include the following:
• Triggering a sound effects playback machine when a specific
snapshot is recalled.
• Lighting a tally light whenever a fader is raised above a mini-
mum threshold.
• Flashing or lighting a custom beacon or LED as a reminder of
vital console mode, such as Solo in Place.
• Initiating power up of amplifiers and other down-stream sys-
tems when VENUE system is started up or shut down.
GPI functions are managed using the Events list on the
Options > Events tab. For more information, see Chapter 21,
“Events.”
To connect GPI devices to the E3 engine:
1 Connect one end of a DB9 cable (not included) to the GPI port
on the back panel of the E3 engine.
2 Connect the other end to the appropriate GPI port on the exter-
nal device.
10 – ECx Port
This port provides connection to a computer or router to enable
ECx Ethernet Control (remote control of the VENUE system).
See Chapter 31, “ECx Ethernet Control” for more information.
11 – AC Power Input
The AC power input accepts a standard IEC AC power cable
(included). The E3 engine power supply is auto power selecting
(100V–240V, 50–60 Hz), and automatically works with a
standard modular power cable when connected to an AC
receptacle in any country.
Power Switch
(Front Panel)
The sliding power switch on the front panel of E3 engine powers
the device on and off. The associated LED lights to indicate the
E3 engine is powered on and ready for use.
Interior Secure USB Port
One USB 2.0 port is located within the E3 engine itself to connect
and securely protect an iLok Smart Key. Use this port to keep one
“master” iLok and its plug-in assets with the console at all times,
safe from damage or loss.
Front Panel USB Port
Connect iLok Smart Keys (for plug-in authorization), USB flash
drives (for data transfer and/or 2-track recording/playback) or
other compatible USB devices to these ports.
The top panel of the E3 engine must be removed to access
the secure USB port. See “E3 Engine Secure USB Port” on
page 315.
