Front and rear of the 2U high 19-inch rack-mountable Hiltron HCS-4 satellite communications controller.
Hiltron Communications, a provider of satellite equipment and system integration, said that its latest-generation HCS-4 satellite communications controller has seen a significant number of customized system deployments in recent months. The HCS-4 was developed from its HCS3 predecessor and forms the central control element for a wide range of satcom applications. These include easy switchover between devices such as downconverters, high power amplifiers, waveguides
The Hiltron HCS-4 can also be used to control and monitor optical-fiber transceivers and antenna heaters. Other features include an N-1 redundancy switch and BUC/HPA controller, LNB supply, 2-1 LNB redundancy switch controller, a fully redundant low-noise 10 MHz reference generator, GPS synchronization and automatic switchover.
The HCS-4 is available as a 2U high 19-inch rack mount unit with main and backup power supplies plus 13 slots for active modules. Also available are two chassis mountable frames accommodating up to 6 or up to 14 active modules respectively. All three versions can be powered from 24 volts DC and are operated via an intuitive HTML-based graphic interface. Modules are hot swappable to allow easy exchange. Any new or replaced module is automatically sensed and its address registered.
All units in the family have SNMP remote control, hot-swappable dual redundant power supply and an internal data bus.
When configured as an antenna controller, the HCS-4 accommodates a freely selectable combination of axis controller cards for SSI-encoders, resolvers or potentiometer-angle readers as well as an optional integrated antenna de-icing controller card.
The range of modules currently available for standard and customized solutions comprises:
* HCS4-10M 10 MHz reference source. This allows signal distribution to a switchable internal bus and three external outputs individually switchable between off/0/9 dB. It has a very low noise and highly stable internal VCXO plus an internal GPS receiver and can be synchronized with GPS or station clock.
* HCS4-DBT Dual Base T for LNBs and BUCs with variable supply voltage for LNB/BUC, individually switchable 10 MHz insertion (0/9 dBm), RF level detection.
* L-Band switch units (HCS4-SW), a transfer switch version (HCS4-LST) and a 2:1 redundant-switch version (HCS4-L21).
* HCS4-EXT controller module for equipment monitoring and control.
* De-icing controller with two main heater circuits up to 20 A each and an independent feed heater circuit (24 or 230 V) plus current, voltage and temperature monitoring.
Also available are external modules that integrate seamlessly with HCS-4:
* HCS4-PD2 compact dual channel power detector, up to 18 GHz.
* HACUX-ANE wind speed sensor.
* HSACUX-DIM2 ultra-compact combination of GPS receiver, flux gate compass and dual-plane high-precision inclinometer (58 x 64 x 36 mm), fully weatherproof.
