RC1500B Single Axis Tracking Antenna Controller
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 On CONFIG mode item. When the flag is set (1) the
user has access to all controller modes (subject to the state of the Remote Enable CONFIG mode
item). 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 Autopol Enable, Remote 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 On CONFIG item. This 5 digit code is contained in a removable
appendix B at the end of this manual, 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 Sys CONFIG mode item.
2.6 AutoPol
The AutoPol feature slaves the RC1500's polarization control to an output derived from a
satellite receiver. The RC1500 has an AutoPol input accessible via connector J1 on the back of
the unit. When the controller is operating in MANUAL or REMOTE modes, this input is
monitored and the polarotor is controlled according to a digital level present at this input.
To configure the controller for AutoPol operation, the user must have:
1. a suitable output available on the satellite receiver which is connected properly to the
AutoPol input of the RC1500,
2. the polarity of the AutoPol input must be specified (Autopol Level CONFIG mode item), and
3. the AutoPol feature must be enabled (Autopol Enable CONFIG mode item).
When the polarity of the AutoPol input is specified, the user is informing the controller that a
given AutoPol input level (high or low) corresponds to vertical polarization. Configuring the
AutoPol system during installation is covered in more detail in chapter 3, and the CONFIG mode
prompts which enable and specify the polarity of the AutoPol input are described in Chapter 5 in
the CONFIG mode section.
