UDP Interface for Telemetry Data Flow
The telemetry data flow (TM) is available on a UDP port in multicast mode. The UDP TM service can be
controlled from registry keys (see section: 4.2.8.10 UDP Telemetry Data).

Cortex Connection to the External World

Interconnection Panels and Associated Cables
Refer to Annex 5 to determine which of the following configurations is supplied with your Cortex CRT Quantum
Unit.
The 3U Interconnection Panel consists of a printed circuit board mounted on a metal panel and connected to the
68-pin male connector of the Digital I/O board via a Vport Samtec cable.
The signals corresponding to Downlink IF inputs (except the Auxiliary ones), Uplink IF outputs and 5/10 MHz
Reference clock inputs are routed to the Interconnection Panel using double-shield RG223/U coaxial cables.
Each single coaxial cable is marked at both ends by a sleeve to easily identify the proper connections.
The signals corresponding to Downlink Auxiliary inputs, Uplink Video modulating inputs, Time code and 1PPS
inputs are routed to the Interconnection Panel using a dedicated multiple cable based on double-shield FILOTEX
21822 coaxial cable. Each coaxial cable is marked at panel end by a sleeve to easily identify the proper
connections.
The signals corresponding to Video, AGC and tracking AZ/EL outputs are routed to the Interconnection Panel
using another dedicated multiple cable based on double-shield FILOTEX 21822 coaxial cable. Each coaxial cable
is marked at panel end by a sleeve.
With the optional Embedded Frequency Board, the RF/IF signals (2 nominal outputs and 3 nominal inputs) are
directly at the rear panel of the CRT.
