J21 Analog beacon level input
Connector Type: D-Sub9 female
The ACU19V2 preferably is used together with the sat-nms LBRX beacon receiver. With the sat-
nms LBRX the ACU talks though UDP or TCP over IP, no additional cabling is required in this
case. At J21 the ACU19V2 provides an analog interface to third party beacon receivers.

J6, J7 and J8 Polarisation and Az/ El Angle encoders
Connector Type: J7,J8 D-Sub25 male, J6 D-Sub9 male
The sat-nms ACU19V2 provides the possibility to connect two different types of angle encoders
at the azimuth and elevation axis: optical SSI encoders (S) and Resolvers (R). The polarisation
axis is always a Resolver (R) type
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: ACU19V2-SSR contains SSI interfaces at azimuth and elevation axis and an resolver
interface at polarisation axis.
SSI encoder interface J7, J8
The SSI positional encoder may be powered from the ACU internal power supply. +24V is
provided as standard at the connector. To avoid ground loops, the cable shield should be
