14.14. VORTAC_Controller
Summary: The VORTAC Controller component is designed to control embedded
identifier tone elements to simulate VOR and TACAN radios.
Description: The VORTAC Controller handles the timing of the VOR and TACAN
tones to prevent overlap. Seven components are needed to implement a complete
VORTAC simulation in a model. The TACAN and VOR radios each consist of a
Transceiver, RCU, and MorseKeyer. Both MorseKeyers are driven by one
VORTAC Controller. The VOTAC Controller will control (connect to) the Enable
variable of the VOR and TACAN Morsekeyers to keep proper timing of the morse
code transmission.
The MorseKeyer reports a busy flag to the VORTAC Controller to ensure accurate
timing of the morse code transmissions. The busy variable of both MorseKeyers
must be connected to the VOR_Busy and TACAN_Busy variables in the VORTAC
Controller. (In some versions of ACE Studio, the VOR_Busy and TACAN_Busy
variables are only visible in the component’s “Full View.”)

Control Inputs
Enable
Type Default Value
boolean True
Description: When True VORTAC_Controller is enabled.
Ident
Type Default Value
ident n/a
Description: The ASCII characters that drive the MorseKeyer. Ident
is a special variable Type which is defined as ASCII characters con-
catenated together. A HostIn component must be used to drive this
parameter.
Interval
Type Default Value
uint16 1
Description: Used to set the delay between words. Units are in sec-
onds.
TACAN_B
usy
Type Default Value
boolean True
Description: Connects to the TACAN MorseKeyer enable.
VOR_Bus
y
Type Default Value
boolean True
Description: Connects to the VOR MorseKeyer enable.
