HPx Hardware

Expand all

Do you have a product to convert analogue radar signals to an ASTERIX CAT-240 network stream? 

Yes, the HPx-346 product is a small form factor, combined analogue radar input and network radar video distribution unit.

Can you interface to a Furuno series 2xx8 radar? 

Yes, we are familiar with FAR-2xx8 radars and our HPx radar interface products can be used to connect to the "sub display" output from them.

Can you interface to other radars (e.g. JRC, Furuno, Simrad, Raymarine, etc.)? 

Almost always yes. A list of radars we are known to have interfaced to can be found on our Supported Radars page, but there are almost certainly many others our customers have used that we’re not aware of at present. If you have a radar that’s not on the list, please get in touch for more information.

Do you have a product to convert a LAN radar stream to analogue signals, i.e. ethernet in, video, trigger, ARP and ACP out? 

Yes, we can accept many different ethernet radar protocols as inputs (including ASTERIX CAT-240 as well as various proprietary formats from radar manufacturers) and the HPx-310 radar output card can be used to drive analogue signals as outputs.

Where can I find the newest device drivers for your HPx radar cards? 

The latest HPx drivers for Linux and Windows are available free of charge within your warranty period. Please contact us for details.

How do you connect to a Sperry DCU? 

Sperry output is bespoke but we can either interface to the Sperry radar’s transceiver directly, or to the DCU.

The transceiver’s signals are directly compatible with the HPx-346 and cable P/N 346-800.

The DCU’s signals are slightly different so would need some conditioning and a different radar input cable would be required, however the same HPx-346 enclosure applies.

Feel free to contact us for options.

Can I use one HPx radar interface card to acquire data from two radars? 

The HPx-410 dual channel radar interface card supports two independent sets of radar inputs and can either assist with dual redundancy from a single radar, or can acquire two streams of data simultaneously. If you want to perform tracking from two different radars, you'll need two instances of the SPx Server.

How can I distribute network video from 2 different radars (with different rotations) connected to the same HPx-410 dual channel radar input card? 

Cambridge Pixel's HPxToNet program manages two independent radar sources and can distribute two channels of radar video for processing.

Can the HPx-346 distribute radar video as a multicast stream? 

Yes, the HPx-346 can send multicast video on the network. This would normally be ASTERIX CAT-240.

What versions of Windows are supported by the HPx radar input cards? 

Cambridge Pixel generically supports Microsoft Windows 10 and 11 Operating Systems.

I have an old HPx radar input card that I need to replace - what are my options? 

The HPx family of cards are backwards compatible so upgrading to the latest generation (currently the HPx-410 PCI Express card) is relatively simple. The correct device drivers will be required and your application may need to be recompiled against the current SPx library.

Can you supply cables for use with your HPx radar cards? 

Yes, we have a variety of options for all our radar cards so please contact us for more information

Do you have power consumption details for your radar interface cards? 

The HPx-180 uses around 2W.  The HPx-346 uses around 5W.  The HPx-410e and HPx-450 use around 10W.

What does "highest-wins to reduce the data rate" mean? 

The HPx radar input cards can combine consecutive samples in range if desired, to reduce the number of samples per spoke of data, e.g. down to 2048 or 4096 bytes. Where samples are combined, the highest value is used so that returns from small targets are not lost.

Does the HPx-346 support dual redundant Ethernet output? 

Yes, there is a variant of the HPx-346 which has dual Ethernet capability. Contact us for details.
