alarm three alert tones indicating a timed event is about to occur.

alert tone A high-frequency chime. Refer to Chapter 6 for details about when you will hear this.

alternate action key A toggle key that switches back and forth between two states with each press; such as Power On/Off.

button A button or key on a source controller (i.e. any controller except the PIC-200).

capture To teach the PIC-200 a command code from a source remote controller.

context-sensitive symbol In Edit mode, a display character representing a double function key (such as , , , ) that may be interpreted and displayed differently after completion than when entered.

current location The last PAGE-KEY location executed.

cursor A pointer represented by a hyphen which indicates program position.

direct-digit method of setting the clock using the numeric keys. Resets the seconds count to :00.

direct-access PAGE keys The , , and keys.

display The liquid crystal window which shows the time and status .

event queue Chronological listing of event timers awaiting execution.

event timer Alarm that automatically operates a stored PIC-200 command or sequence of commands at the specified time(s).

Infrared Module The removable head on the upper back part of the PIC-200 that contains the infrared transmitter and associated circuitry.

interval Relative event timer setting; can be used to insert pauses within programs.

key Any of the physical keys on the PIC-200 keyboard. (location) KEY Any of the 16 keys, through and through , used to represent the two-part storage location address. key pairs The rocker keys , , and .

location Storage space in the PIC-200 programmable memory. Each location is referenced by PAGE and KEY.

null program An empty program; a location without any contents.

number of sends the number of times the PIC-200 sends an infrared signal when a key is pressed.

one-shot An infrared code that transmits once, then stops.

one-step access A single keypress used to operate programs stored on the direct access PAGE keys.

operate To execute a program stored in the PIC-200.

operating key Any of 20 keys used to operate the PIC-200. See PIC-200 Parts: An illustrated guide.

PAGE-KEY location The place in PIC-200 memory where a program is stored.

period The number of microseconds (between 17 and 40 in the PIC-200) in each remote controller code cycle.

program A command or sequence of actions assigned to a specific location on your PIC-200. Programs can include remote controller codes, timed events, loops and other program definitions. Each program contains a maximum of 62 keystrokes.

programming keys Any one of 12 keys used to program and edit the PIC-200. See PIC-200 Parts: An illustrated guide.

recursion When a program calls itself putting the processor in an infinite loop.

reject tone A short low-frequency buzz. See Chapter 6 for details on when this occurs.

repeat loop A section of program that is executed repeatedly a specified number of times.

reset To restart the microprocessor by pressing the switch located in the hole between and . Reset clears the event queue. Reset clears the event queue and key definitions.

reverse capture The display symbol indicating that the source remote controller only sends its command one or two times per keypress.

scanning method A method of setting the clock using the key-pairs. Preserves the current seconds count.

sequence A program that combines two or more operations at a single location.

sequence send rate The amount of time between each code send. The PIC-200 normally uses a .2 second delay, but this can be changed to a 1.0 second delay indicated by on the display.

single-step verification Procedure for checking out program sequences by executing each program element in succession.

source remote controller One of your remote controllers used to teach the PIC-200 the infrared command code required to operate your component(s).

stand-alone event timer An event time that is not part of a program.

status line Eight-digit display at the bottom half of the LCD window.

storage location One of 259 PIC-200 memory spaces where programs are kept.

syntax Rules for programming. See "PIC-200 Syntax Guide" .

teach To learn a sequence of actions or a remote controller command.

three-step access A three keypress sequence : + PAGE location + KEY location; used to operate a program stored at that location.

time display Six character line in the upper half of the display window.

time-out When the PIC-200 display goes off after a few minutes of non-use to conserve the battery. Any programming operation in progress will be canceled.

two-step access Operating a program stored on the , , or PAGES by pressing the corresponding direct PAGE access key and the KEY location.

unattended operation Automatic execution of the PIC-200 through the use of timed events.

verification Ensuring that remote controller commands captured on the PIC-200 perform the intended operation on your component.

wake-up To turn on the PIC-200 display after a time-out by pressing any key.
