EXTERNAL INTERFACES
4.1 Overview
This chapter describes the external interfaces available to the user.
The MPA Hub Mount external interface connectors (J5 and J6) are
located on the front panel of the unit (Figure 2-1).
4.1.1
Control Mode Hierarchy
The MPA Hub Mount may be controlled from the front panel of the
unit (LOCAL mode) or via serial interface connector J6 (REMOTE
mode). The RF Switch Interface connector (J5) provides additional
control functions for redundant system operation and user external
interlock circuits
The LCL/RMT switch on the front panel of the amplifier
determines the amplifier control mode (LOCAL or REMOTE). The
LCL/RMT switch transfers the control point from the amplifier
front panel to a remote control device. At any time, the LCL/RMT
switch can be used to establish LOCAL mode operation. (Remote
control devices cannot affect selection of the LOCAL or REMOTE
control mode.)
