RC4000 ACU Boardset
3.1.4 Display Layout
The following screen shows many elements common to RC4000 mode displays.
AZIM: 31561
ELEV: 11060
POL: -45.0 H
WAITING FOR NEXT PEAKUP
MODE TITLE: in the upper right corner the title of the current RC4000 mode is displayed – in this
example TRACK designates that the RC4000 is currently in track mode.
NOTE: if the mode title is preceded by an exclamation point ( ! ), the mode was initiated by a remote
command.
DATA LABELS: since each mode presents a unique set of data, labels describing the data must be
presented. The label will typically be followed by a colon to delimit between the label and the actual data.
In the example shown, AZIM: is the label for the current azimuth pulse count.
DATA VALUES: the current value of relevant data for the mode is displayed following the appropriate
data label. In the example, the current azimuth pulse count (AZIM:) is 31561. Likewise the current
satellite being tracked (SAT:) is BRASIL A1.
USER PROMPTS: since each mode requires unique (but similar) keypad inputs, prompts for relevant
user action are included on the fourth line to the extent possible. In the above example, <0> tells the user
that pushing the 0 key will transition the RC4000 to TRACK MENU mode. There are several types of
user data inputs as described in 3.1.3.
USER INFORMATION: when room allows, information about the current state of the RC4000 is
displayed. In the above example, "WAITING FOR NEXT PEAKUP" describes the fact that since the
RC4000 is currently in the IDLE portion of the STEP track operation the controller is waiting until the
appropriate calculated time to perform the next peakup movement.
TIME: in some modes where data (such as azimuth position) may not change for long periods of time,
the current time is displayed to reassure the user that the RC4000 is functioning. In the above example,
the current system time (16:03) is displayed with the colon flashing once per second.
ALARM STATUS: while not shown in the above example, row 4 is used to display any alarm conditions
the RC4000 has detected. The alarm message will alternate with the text normally on row 4. See section
3.4 for more description of the alarm system.
