HDS 8 Questions

Elshere, L · Post by **Elshere, L** » Sun Apr 03, 2011 6:53 pm

Hi Ken,
I resently installed a new HDS 8, HDS 7 and Structure Scan.

The main issues I am having is with the HDS 8. The temp. was working fine

and this week end it stop.

I took the HDS 8 and moved it to the front where I have my HDS 7. The temp. did not show up. I plugged in my HDS 7 into the HDS 8 transducer and it works fine. I went into the installation section of the HDS 8 and went to the transducers and it said Unknown. I reset it back to HST-WSBL and saved. Nothing. I plugged in a brand new in the box transducer - HST-WSBL and still nothing.

The other issuse is almost the same as Mike has posted. This week end the HDS-8 started to taking a long time to wake up, the display was very dim and took a while to brighten. I recieved my HDS-8 and Structure Scan on 2-27 and my HDS-7 on 3-23-11. The last issuse is with both units. I am getting trolling motor interferance in both units.

I replaced my LMS-332C and LCX-26CHD with the new HDS units. I never had a problem with trolling motor interferance before. I installed seperate power and ground wires to both units, straight to the batterys. It also effects the Structure Scan. Can you give me a little help on these issuses

Are the units networked together with an ethernet cable?

No. They are separate units. The only thing that they share is the Structure Scan.

The reason I asked if they are networked via an ethernet cable is because if they are, when you make a setting change on one unit it makes the same change on the other unit because of the ethernet network. I believe that the Structure Scan module being hooked up to both units will network them in the same manner.

To make sure each unit is using the transducer and temp. sensor you want do this; Unhook the ethernet cable from the back of the unit. Hit menu twice, go to Network, go to Data Sources, go to Sonar and hit enter. Go to water temperature and hit menu. Go down to Scope and hit enter, select Local and hit enter.

Global means the unit can use any device in the boat, Local means the unit can only use the devices that are plugged into it.

Hi Ken,

I stand corrected. They are networked with the ethernet cable. Sence the last post. I did find out how to reset my transducer. Under the Network section of the menu. I took the boat out tonight and when I turn on the Structure Scan, the transducer when off again. It also turned off the HDS 7. I reset both units and they are holding. Could my problem be in the Structure Scan?

You are saying that the transducer for the Structure Scan is not working. When you choose a Structure Scan screen does the unit say "no source" on the screen? If so then it is a power issue with the LSS-1. The power cable for the Structure Scan needs to be connected to a hot and ground and the yellow wire needs to be connected to the yellow wire in the HDS units power cable, yes the two yellow wires are connected to each other. This way when the HDS unit is turned on the LSS-1 is turned on at the same time.

The Structure Scan does work. I have it setup with it's own power switch. I have full signal at both units. The problem is when I turn on the Structure Scan, it turns off the units temp. When I go back in to reset them, the local has ????. I have to put it on Global to have it work at all. Which will also turn off in a very short period of time. I did go in last night and disconnect the Ethernet Cable from both units as you suggested and I was able to put both of them on Local. They did hold fine. I powered down and re-connected the Ethernet Cable to both units and when I powered up both units, the temp. was gone on the HDS 7. I checked the setting and It had the same local ???? I have been running the units for a couple of weeks with out any problems. This just started last weekend.

Ken,

I have an update for you. I talk to Greg, at Lowrance this morning. I told him of my problem with the temp. leaving my screens. We went through the whole thing with re-setting the transducers to local (This Unit). Making sure the correct transducers is selected from the pull down menu. He has never heard of this problem before. I ask him if the LSS-1 can go bad? He again said he has never encountered this problem. He ask me to do a soft start to both units. Maybe some settings have been changed. I dissconected the LSS-1 from both units and completed the task to the HDS 8 & HDS 7. I connected the LSS-1 to the HDS 7 frist when ask. The LSS-1 was enabled in the HDS 7. I then went to the HDS 8 and did the same thing. I connected the LSS-1 when ask. The LSS-1 was enabled in the HDS 8. I looked up front to my HDS 7 and the temp. was gone again. The temp stayed on the HDS 8. I then look at the temp. setting under the Network section on the HDS 7 and again, the local setting was ???? I powered both units down and turned the power off to the LSS-1 and disconnected it from the HDS 7 and did another soft start. I am leaving the LSS-1 off of the HDS 7. It is better to have it working on one unit, than having issuses with both. I will call Greg back in the morning and let him know the results of the re-boots and the rest of it. I am going to send the LSS-1 back for testing once I get a return number. This maybe the frist of it's kind and I hope it is the last. I will let you know the results of the testing and post the results.

Might want to read through all these posts. I'm not sure if it directly addresses your problem but it seems that there is a solution to having temp displayed only from the transducer directly attached to the head unit, as long as there is a temp probe in that tranducer.
