RC2000A Dual Axis Antenna Controller Chapter 2 Basic Functions 13
Chapter 2 BASIC FUNCTION DESCRIPTION
This chapter describes the controller's front panel layout, user interface and basic operation. When the
user has completed this chapter, he or she should have a basic understanding of the various operating
modes of the unit and be able to use the keyboard and liquid crystal display (LCD) to navigate through
those modes.
2.1 Front Panel
The front panel (figure 2.1) of the RC2000A contains an ON/OFF switch, a 2 row by 40 column backlit
LCD, and a 4 by 4 matrix keypad with tactile feedback. On the rack mount version of the controller, an
AC line fuse is built into the Power Entry Module in the back panel. A 12-amp circuit breaker (located
on the back of the unit) protects the controller's 36-volt actuator drive circuits. When a circuit breaker of
this type trips, it will protrude from its mounting bezel. To reset the circuit breaker, turn the power switch
off, wait a few minutes for the circuit breaker to cool down, then depress the breaker so that it latches
and is even with the bezel.
Figure 2.1
The field in the upper right hand corner of the LCD is reserved for the display of the current mode of the
controller. The various modes are introduced in the following section. If an error condition is active, an
error message will periodically flash across the bottom row of the display. Error messages are
discussed in chapter 6. Chapter 4 explains the contents of every field on the display for all of the
various controller modes.
An examination of the keyboard in figure 2.2 reveals that many of the keys have 2 or more labels. The
function of each key is determined by the current mode of the controller. The various modes are
discussed in the following section.
