The sat-nms ACU19V provides the possibility to connect two different types of angle encoders:
optical SSI encoders (S) and Resolvers (R). Please refer to chapter
Interfaces to the antenna/ Pin
descriptions
for more detailed informations. You have to decide at point of order which variant
you want to have. The angle encoder type is specified by an add-on to the name of the unit. The
sequence is azimuth, elevation, polarisation An example: ACU19-SSR contains SSI interfaces at
azimuth and elevation axis and a resolver interface at polarisation axis.
The sat-nms ACU19V2 provides a dry contact Alarm interface. Please refer to chapter
Interfaces
to the antenna/ Pin descriptions
for more detailed informations.
The sat-nms ACU19V2 provides an ethernet (http) interface for remote controlling. An internal
webserver provides a clearly arranged webpage where all settings and states can be monitored
and controlled. Please refer to chapter
Operation
and
Remote control
for more detailed
information. A serial interface (RS232) is available on demand.
The sat-nms ACU19V2 already contains all internal needed power supplies. As they are wide-
range types it is possible to connect nearly all worldwide available single phase mains. Please
refer to chapter
Specifications
for more detailed informations.
3.9 Serial interface angle display
The sat-nms ACU19V2 provides via a serial RS422 interface the angle information to an external
control unit e.g. PMCU from GD Satcom or sat-nms LCPD. Please refer to chapter
Interfaces to
the antenna/ Pin descriptions
for more detailed informations.
The following chapter describes how to install the ACU19V2 mechanically and electrically.
Additional a detailed start-up procedure is given in this chapter.
The sat-nms ACU19V2 is completely integrated into a 1RU 19inch case with standard mounting
holes. The case of the sat-nms ACU19V2 is not strong enough to carry the complete unit only on
the front mounting holes! Because of that, take care that the sat-nms ACU19V2 is placed onto a
bar guide that carries the complete weight of the sat-nms ACU19V2. The screws have to be fixed
properly to keep the sat-nms ACU19V2 in its position.
4.2 Interfaces to the Antenna, Pin descriptions
ATTENTION! Electrical installation shall be carried out only by qualified personnel who are
instructed and aware of hazards of electrical shocks.
All connectors of the sat-nms ACU19V2 are located at the rear side of the case. The following
