300 QUESTIONS AND ANSWERS
1. Q: What is the primary function of an Extron control system? ANSWER
To provide centralized control and automation of AV equipment, lighting,
environmental systems, and other devices in a room or facility.
2. Q: What does IP stand for in the context of Extron control systems?
ANSWER Internet Protocol - used for network-based communication and
control.
3. Q: What is the difference between a control processor and a control
interface? ANSWER A control processor is the central brain that executes
control logic, while a control interface is the user interaction device
(touchpanel, button panel, etc.).
4. Q: What is the maximum number of devices that can be controlled by an
Extron IP Link Pro control processor? ANSWER Up to 256 IP devices and
unlimited serial/IR devices (depending on available ports).
5. Q: What protocol does Extron use for device communication over
Ethernet? ANSWER Extron uses IP Link protocol for communication
between control processors and compatible devices.
6. Q: What is the purpose of Global Configurator in Extron systems?
ANSWER Global Configurator is used to configure and manage IP Link-
enabled Extron devices on a network.
7. Q: What file format does Extron use for control system programs?
ANSWER .EDP (Extron Database Program) files for GUI Control Designer
projects.
8. Q: What is the standard baud rate for Extron serial communication?
ANSWER 9600 baud, 8 data bits, 1 stop bit, no parity (9600,8,N,1).
,9. Q: What is the purpose of a control system's feedback mechanism?
ANSWER To provide real-time status information from controlled devices
back to the control system and user interface.
10. Q: What does SIS stand for in Extron terminology? ANSWER Simple
Instruction Set - Extron's command protocol for device control.
11. Q: What is the maximum cable length for RS-232 serial
communication? ANSWER Typically 50 feet (15 meters) without signal
boosters or converters.
12. Q: What voltage levels are used in RS-232 communication? ANSWER
±3V to ±25V (typically ±12V), where negative voltage represents logic 1 and
positive voltage represents logic 0.
13. Q: What is the purpose of a crosspoint switch in AV systems?
ANSWER To route any input to any output in a matrix configuration, allowing
flexible signal distribution.
14. Q: What does EDID stand for and why is it important? ANSWER
Extended Display Identification Data - provides display capabilities information
for proper signal formatting.
15. Q: What is the difference between simplex and duplex communication?
ANSWER Simplex allows communication in only one direction, while duplex
allows bidirectional communication.
16. Q: What is the purpose of IR (Infrared) control? ANSWER To control
devices wirelessly using infrared light signals, typically for consumer
electronics.
17. Q: What is a control system's event-driven architecture? ANSWER A
programming model where actions are triggered by events (button presses,
sensor inputs, time events, etc.).
18. Q: What does API stand for in control systems? ANSWER Application
Programming Interface - defines how software components communicate with
each other.
19. Q: What is the purpose of system polling in control systems? ANSWER
To regularly check the status of controlled devices to maintain accurate
feedback information.
20. Q: What is a control system macro? ANSWER A pre-programmed
sequence of commands that can be executed with a single trigger.
, 21. Q: What is the difference between volatile and non-volatile memory?
ANSWER Volatile memory loses data when power is removed (RAM), while
non-volatile memory retains data (flash memory, EEPROM).
22. Q: What is the purpose of a system's startup sequence? ANSWER To
initialize all devices and establish communication in a predetermined order
when the system powers on.
23. Q: What does CEC stand for in HDMI systems? ANSWER Consumer
Electronics Control - allows HDMI devices to control each other through the
HDMI cable.
24. Q: What is the purpose of a control system's security features?
ANSWER To restrict access to system functions and prevent unauthorized
changes or operation.
25. Q: What is the difference between analog and digital control signals?
ANSWER Analog signals vary continuously over a range, while digital signals
have discrete states (typically on/off or high/low).
26. Q: What is a control system's user privilege level? ANSWER Different
access levels that determine what functions a user can perform (operator,
technician, administrator).
27. Q: What is the purpose of a system's diagnostic mode? ANSWER To
provide detailed information about system operation and help troubleshoot
problems.
28. Q: What does TCP/IP stand for? ANSWER Transmission Control
Protocol/Internet Protocol - the standard protocol suite for network
communication.
29. Q: What is the purpose of a control system's scheduler? ANSWER To
automatically execute commands or system changes based on time and date
parameters.
30. Q: What is a control system's state machine? ANSWER A
programming model that manages system behavior based on current conditions
and input events.
31. Q: What is the difference between a preset and a scene in control
systems? ANSWER A preset typically refers to saved device settings, while a
scene encompasses multiple device states and room conditions.
