CONTROL-1500A Single Axis Antenna Controller
1. 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.
2. 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.

Expert Access
An Expert Access flag is maintained by the controller. The user can inspect and change the
state of this flag via the Expert On CONFIG mode item. When the flag is set (Expert On
CONFIG item has a value of 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 (Expert
Access CONFIG item has a value of 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,
the user only has access to the Autopol Enable, Remote Enable, and Expert On 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 appendix A
of this manual. Note that the Expert Access flag is set whenever the controller's memory is
cleared via the Reset Sys CONFIG mode item.

AutoPol
The AutoPol feature slaves the control1500's polarization control to a digital output derived from a
satellite receiver. The control-1500's 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 polarization control device 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 CONTROL-1500 (AutoPol input and Return connections are required),
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 4 in the CONFIG mode section.
