No fishfinder option with Hsb2 Pathfinder Series Radar/Chartplotter Display
No fishfinder option with hsb2 Pathfinder Series Radar/Chartplotter Display

In order for a hsb2 Pathfinder Series Radar or Chartplotter Display to support fishfinder features, it must be interfaced to a hsb2 Pathfinder Series Fishfinder Display or to a DSM250/30/300 which in turn has been interfaced via hsb2 communications protocol to a compatible fishfinder transducer.

The first step in troubleshooting the subject problem when the system features a DSM would be to ensure that the DSM's Status LED is illuminated and green. If so, then the problem would be rooted in communications between the display and the DSM. the DSM's Status LED is not illuminated, then the DSM would either not be receiving power power via its power cable or would have suffered an internal circuitry failure. Unfortunately, should a fault be found within the DSM, then the DSM would need to be replaced with a second hand DSM, as Raymarine can no longer provide parts and service for DSM250/30/300 Digital Sounder Modules. Should the DSM's Status LED be illuminated and not be green, then its color and flash code should be compared to the table below.

The following troubleshooting steps should be undertaken when troubleshooting hsb2 communications. The diagrams provided below address how hsb2 communications protocol would be used to interface hsb2 Pathfinder Series Displays to one another and/or to a DSM250 respectively.

- Verify that all Pathfinder Series Displays are equipped with hsb2 communications circuitry

- Verify that the hsb² network is properly terminated (i.e. 2 hsb2 inline termination plugs only and that these hsb2 inline termination plugs have been installed within the two displays or the display and DSM250 forming the ends of the hsb2 daisy chain (See diagram below). If a DSM30 or DSM300 fishfinder sounder module has been installed, then the DSM should be installed at one end of the hsb2 daisy chain. The DSM250 requires a hsb2 Inline Termination Plug, while the DSM30 and DSM300 are internally terminated. If the display's hsb2 port is gray, then no hsb2 inline termination plug has been installed in the display's port. If the display's hsb2 port is black, then you are looking are the male end of a hsb2 inline termination plug.

- Verify that the hsb2 inline termination plug has been removed from any display into which a hsb2 Y-Cable has been inserted (see diagram above)

- Verify that all hsb cables are securely seated and have proper strain relief

- Verify that there are no damaged hsb cables by visually inspecting and performing continuity tests

- Verify that the hsb cable(s) have not been subjected to excessively small radius bends (<6 inch diameter). Subjecting these cables to excessively tight bends can permanently damage the cables. Excess cable should be loosely coiled and secured to a bulkhead

- If the system contains more than 2 hsb² nodes, attempt fault isolation to identify the faulty component (i.e. connect 2 nodes at time to verify communications between the two nodes)

- Verify that no more than 2 C-Map SW+ regions are being served on the hsb² network.

- Perform resistance tests and continuity tests of the hsb² components:
-- Terminators (uninstalled from hsb² port): 120 +/- 2 ohms across the HSVB_POS & HSVB_NEG pins (see diagram above)
-- Pathfinders (power off): 2200 +/- 50 ohms across the HSVB_POS & HSVB_NEG pins ... should results differ, then the display's hsb2 communications circuitry has failed.
--Terminators (installed): values should drop by approximately 5 ohms from the value measured prior to installation ... should results differ, then the display's hsb2 communications circuitry has failed.
-- For multiple display systems, with the system's hsb² displays reconnected to the hsb² network and the Pathfinder PC disconnected from the hsb² network, measure the resistance of the network through the hsb² cable:

Displays.......... Resistance

1____________114

2____________108

3____________103

4____________99

5____________94

6____________90

7____________87

8____________84

- For maximum system performance, verify that all Pathfinder Series Displays have v4.11 software installed within them ... please note that Raymarine's Product Repair Center can no longer update the software within these hsb2 Pathfinder Series Displays

Unfortunately, should one or more of the displays or DSM have failed hsb2 communications circuitry, then it must be replaced with a second hand instance of the same product, as Raymarine's Product Repair Center can no longer service these displays.
