Mode Access - RESEARCH CONCEPTS RC1500B Manual

RC1500B Single Axis Tracking Antenna Controller
prompt message on the bottom row of the display provides data entry instructions. For some
CONFIG mode items, one of the two possible data values lower case text. For these items the
upper case prompt specifies the default value of the parameter.
LIMITS
705 24 431
7-SET CCW/DN
LIM
This mode allows the user to set the antenna's logical limits. To set a logical limit the user jogs
the antenna to the position of the desired limit and hits the 7 key. The azimuth CCW or elevation
DOWN limits are set first. After this limit is set the user is prompted to set the azimuth CW or
elevation UP limit. Once the limits are set the antenna cannot be moved (except in LIMITS
mode) to a position that is not within the logical limits. In LIMITS mode the controller will not
detect an antenna jammed condition. When the first limit is set the antenna position is initialized
to 30.
TRACK
567 56 H 668
PEAKING
TRACK mode is activated to track an inclined orbit satellite. TRACK mode is slightly different
than the other modes described above in that TRACK mode cannot be reached directly through
the use of the MODE key. TRACK mode can be entered only via the SETUP or AUTO modes.
When TRACK mode is active the track sub-mode is displayed in the lower right hand corner of
the display. The TRACK sub-modes are step track (STP), search (SEA), memory track (MEM),
menu (MNU), and error (ERR). TRACK mode is described in Chapters 4 and 5.
More detailed information is available concerning each of the modes described above in Chapter
5 of this manual.

Mode Access

Access to some modes is restricted in some circumstances. Here are the conditions which can
restrict access to certain modes:
1. TRACK mode can only be entered via the AUTO or SETUP modes - it cannot be entered via
the MODE key. When TRACK mode is active it is treated as if it were in the operational
mode group. If TRACK mode is active and the user presses the MODE key, control will
transfer to the MANUAL mode. If TRACK mode is active and the user holds the MODE
key in for five seconds and releases, control will transfer to SETUP mode.
2. REMOTE mode is only accessible when the Remote Mode Enable CONFIG mode item is set
to 1. When enabled, REMOTE mode can be activated either via the MODE key or by the
receipt of a command on the serial port. Note that most commands received via the serial
port may be processed while TRACK mode is active.
