[CA] [CA11] Upgrading from SL70 to ev200 and E127’s

Mark,

Q1) The GPS antenna is a Dugital Yachts Dual so has access to both gos and glonass and its hard wired into the existing Sl 70 via the nmea 0183 wire on the power supply cable. So I could either connect this via an actisense module or hardwire into the power supply cable of the E127
However it would be good to have a Raymarine gps Dual if poss) that plugs straight into the backbone.
A1. The Raystar 150 GPS Sensor is designed to do just that.

Q2a) We were of course planning to connect the existing Seatalk network to the new STng back bone via the converter setup so presumably the St60 would have sent depth data to the displays. However now we have the Airmar through hull sounder connected to the DSM 300 that is in turn connected to the STng back bone ( while still not fully connected and working as I have had to virtually rewire the helm to install all the components properly!!!)So...... is it actually worth replacing/ repairing the ST60 and ignoring its old in Hull p79 as I am sure the DSM would take preference on the new network?
A2a. Unfortunately, Raymarine can no longer service ST60/ST60+ Instruments. Additionally, P79 transducers which had been designed to be interfaced to ST40/ST60/ST60+ instruments which determine depth operate at 200kHz. When a DSM is in the system and operating in Auto frequency mode, it would typically ping at 200kHz as well when operating in most of the lake. This may cause the depth seeking instruments using a 200kHz transducer to be unable to determine depth because of interference from the fishfinder transducer. Accordingly, instead of replacing the ST60 Depth with an i60 Depth, it would be recommended that an i70S MFID and an T70278 P79 Smart In-Hull Depth Transducer (should fit within the existing in-hull reservoir) would be recommended for a second depth source to replace the ST60 Depth and analog P79 instrument transducer. As the T70278 P79 Smart In-Hull Depth Transducer operates at a different frequency (235 kHz), it would not be interfered with by a DSM which was pinging a fishfinder transducer at 200kHz or 50kHz. The T70278 P79 Smart In-Hull Depth Transducer and i70S each support SeaTalkng / NMEA 2000 communications and as such each would be interfaced as a spur to the system's backbone rather than connecting the transducer to the instrument as had been the case for the ST60 Depth instrument.

Q2b. I could then add an updated depth display because as of you know its essential to monitor depth here on the lake.
A2b. See the response to Q1.

Q2C. That means no depth reading for a while untill I get the mfds up and running but at the same time I could send the ST60 to Nasua for repair if they still do this??? Could be a stand aline back up ?
A2C. See the response to Q1. Be careful out there with a working depth instrument or fishfinder.
