I would like to put a repeater radar upstairs.
I have a colour RL70 with HSB2 at the lower helm and I know the system is designed to take a repeater but the more I read the Installation manual the more confused I become.


Has anyone actually managed to retrospectively fit a repeater ?

Do I need to connect the HSB2 lead and the seatalk .

I don't need it to speak to the auto helm as that is already linked from the flybridge auto helm repeater, I just want to view Radar.

If I can establish how to connect it Iam interested to hear from anyone wanting to sell a HSB2 mono screen with the required cables.

From what I can tell the cables cost £200-£300 ??????

Power lead
HSB2 lead
HSB2 end terminal x 2
seatalk cable

All of which have to be routed through small holes.

I've a RL70 screen going begging - PM me if you want it, I've some spare cable ends as well, and ordinary shielded cable works

Yes, I did this. You only need the HSB2 cable, not the seatalk cable. As always the complication is routing the cable between the two helms. If you have/buy the RLRC display, you get seamless plotter functionality at both helms as well.
 
Yes you need an HSB2 cable, quite exp. You might as well connect the seatalk becuase it is just a 3 wire system, cheap, any wire will do not Raymarine special stuff. Then you can display all seatalk data on either screen. you need to fit an end resistor at each end of the network (ie 2 of them) but they're cheap and you prob have one already in the back of your current unit
 
You don't need a sea talk cable to the slave display, because the existing unit will already have all the data that comes through the sea talk bus, and the HSB2 interface allows all data to be shared between the two units. If you want a sea talk connection, you can just daisy chain from the nearest connected device, which is probably the autohelm. The only reason I can think of for connecting up the sea talk, is you can then run the slave unit without switching on the master unit, but that also means transferring the c-map card, or buying a spare, which sort of defeats the purpose of linking the two in the first place.
 
Hi Wiggo,

I am just in the process of looking into this now.

There is a cable that is HSB at one end and HSB2 at the other end.

I think you can display a HSB2 screen on a mono HSB screen

BUT not sure which is what I am searching for now.

cheers

hmm, you've sparked a little doubt in my mind now. I only remember connecting the HSB2 cable and the power, but it was a while ago I did it.

On balance I think it probably is worth connecting up the sea talk anyway, as its cheap and easy to do, and you would then have a back up lat/long position displayed on the radar if the master unit crashed.
 
Remeber the hsb2 cable is only 4 cores, hence doesn't seem to have much spare capacity for seatalk data. No matter, connect them all as you say :-)
 
I think I have sourced the answer from a raymarine document issued in 2002.

HSB allows you to connect two screens.

HSB2 allows several screens and can connect to HSB

You can turn a fish finder into a radar with hsb or hsb2 (needs to be hsb to a full function radar)

If you want to also display seatalk information you can add a sea talk connection also but this is optional.

AS I have a separate plotter upstairs then all i need is to attach the hsb to view radar.

The cable appears to be £100 and I may also need which is unclear

2 x end terminals and maybe a HSB/HSB2 converter.
 
When we bought our last boat she had 4 RL displays - 2 RL70's upstairs and RL70 and RL80 downstairs.
They were all of the old HSB(1) standard.
I think that 2 of the RL70s were in fact fish finders.
I wanted the whole lot to be integrated using HSB2.
I removed the lot and took them to Raymarine for upgrading.
It was only then that they told me that they couldnt upgrade them as the system was obsolete so after a little moan, they were able to cobble together a complete hardware upgrade.

Apparently, the fishfinder wouldnt be able to feed depth info into the proposed upgraded system. The solution was to provide a DSM250 (Digital Sounder Module) which had a full HSB2 interface and to change the fishfinders to standard RL70s. I suggest that this isnt the case for your proposel as well.

I spent some time looking around and never came across an HSB to HSB2 lead - will it actually work in your instance? - make sure that the lead isnt designed to make an HSB2 device connect to a standard HSB system. AFAIK HSB only allows 2 devices to be connected together whereas HSB2 is a bus system enabling up to 4 devices.

However, you will find thet the RL80 is a MUCH more readable display than the RL70s - still not much good in direct sunlight though.

Incidentally, throughout the upgrade, Raymarine's help and support was superb - this was a big factor in deciding to order our new "all singing" G Series system.

I have a RL70C in the cabin and want to install a repeater on the flybridge would your RL70 be suitable and if so does it have a colour screen and how much? Please advise where I would need to collect

Afraid, it went long ago

To a forumite, who put some folding stuff into the RNLI pot for it.

Standard hsb1 will not talk to hsb2 unless you upgrade to software which is £££ so when buying make sure you have either hsb1 or hsb 2, I have been there so to save time make sure you have the correct displays.
