ST-TUNE and STI-TUNE Symbols Input Descriptions
INPUT(S) FUNCTION(S)
Func
This signal cycles through the AM, FM, WX, and TV bands. The band
is selected on the rising edge.
AM, FM, WX,
TV
Each of these signals selects one of the four bands directly. The
band is selected on the rising edge.
Mode This signal performs the same function as pressing the MODE button
on the front panel. (The MODE function cycles through PRE, TUNE,
SRCH tuning modes.) The MODE is selected on the rising edge.
Mono This signal (not active in AM mode) performs the same function as
pressing the MONO button on the front panel. This function toggles
on each rising edge.
Mono-On,
Mono-Off
SAP-On,
SAP-Off
Sense-High,
Sense-Low
Disable-Lcl-
Btns When this signal is high, the local functionality of the front panel
buttons is disabled. (The button presses are still reported into the
program on the output of the symbol.)
AM-Station This analog signal is a number that sets the AM frequency of the
unit. Valid AM numbers are 530d through 1710d. Valid AM
increments are by 10, such as 1010d, 1020d, etc. NOTE: If not in the
AM mode, the unit will not go into AM mode when this signal is
received on this line. The signal will set that value for the next time
the unit is put into AM mode.
This analog
signal is a number that sets the FM frequency. Valid FM
numbers are 8950d through 10790d. The number has an implied
decimal point 2 digits from the end and must be sent in this format.
For example, to go to 102.7 FM, the analog number to be sent is
10270d. FM stations are only valid on analog increments of 5,
therefore 10271d is not valid and will go to the next lowest station,
10270d. NOTE: If not in the FM mode, the unit will not go into FM
mode when this signal is received on this line. The signal will set that
value for the next time the unit is put into FM mode.
These signals perform the same functions as pressing the UP or
DOWN buttons on the front panel. NOTE: The front panel buttons
auto-increment after a preset period of time. These UP and DN
signals engage only once on the rising edge. Therefore, in the TUNE
mode, the UP signal increments the station once.
ST-TUNE ONLY - These signals turns SAP reception on or off during
TV mode only. This mode is selected on the rising edge.
These signals directly adjust the sensitivity of tuning. The sensitivity
is selected on the rising edge. NOTE: SENSE-HIGH allows the unit
to recognize weaker stations during the search mode. (Refer to Sig-
Strength in the next table for related information.)
These signals select one of the mono modes directly. The function is
selected on the rising edge.
Up, Dn
Pre, Tune,
Srch Each of these signals selects one of the three modes directly. The
function is selected on the rising edge. These will change the function
of the UP and DOWN buttons. (Refer to Pre-F, Tune-F, and Srch-F in
the next table for related information.) NOTE: In PRE mode, no
function is performed, PRE mode must be programmed in SIMPL
(typically this would be logic to recall stations; see the ST-TUNEB.ZIP
program examples).
FM-Station
ST-TUNE ONLY - These are four modes of TV reception. In each
mode, the channels map to different frequencies. The mode is
effected on the rising edge of the next frequency change.
