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. TRACK mode is
described in Chapter 4.
More detailed information is available concerning each of the modes described above in Chapter 5 of this
manual.
2.4 Mode Access
Access to some modes is restricted in some circumstances. Here are the conditions that 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, 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.
3. The expert access system can restrict access to certain modes. The intent is to avoid corruption of
the operating parameters by inexperienced personnel. The expert access system is described in the
next section.
2.5 Expert Access
An Expert Access flag is maintained by the controller. The user can inspect and change the state of this
flag via the CONFIG mode Expert Access item. When the flag is set (1) the user has access to all
controller modes (subject to the state of the Remote Mode Enable flag described in the preceding
paragraph). When the Expert Access flag is reset (0), the user only has access to the MANUAL, AUTO,
REMOTE, RESET, and CONFIG modes.
The Expert Access flag also controls access to CONFIG mode items. When the flag is reset (0), the user
only has access to the Simultaneous Az/El Enable and Expert Access CONFIG mode items. The user
can toggle the state of the Expert Access flag by entering a 5 digit code at the CONFIG mode 'EXPERT
ACCESS' item. This code is found in Appendix A, a removable page. If the information is lost, call the
factory for assistance. This is done to safeguard from any accidental corruption of operating parameters
by inexperienced personnel. Note that the Expert Access flag is set whenever the controller's memory is
cleared via the Reset System Data CONFIG mode item.
