c125 slave unit chart background issue

[Doug Martin]

I have two c125 displays, one is a slave to the master. Both are updated to v16.49. Has worked fine for two years. Now with both units on in chart mode, the slave unit only shows the base map (no Navionics chart detail). The slave unit does display nav data like boat position, speed, TTG, WPTs, log data. I have checked the connections and have done a factory reset on both units. After the reset, the Navionics chart did come up for a few days. After turning on the slave unit today on the fly bridge, only the base map came up again. Also the Sirus weather detail does not show up on the slave unit but works fine on the master. Please help.

Welcome to the Raymarine Forum Doug,

Not that it should have any impact upon correcting the reported issue, but please note that a/c/e/eS/gS-Series MFD v17.45 software was released late last week, and it is recommended that the MFDs be updated when convenient to do so. Within a system of a/c/e/eS/gS-Series MFDs, the Data Master MFD will be interfaced to the SeaTalkng backbone to receive low bandwidth system data. This low bandwidth data, along with high bandwidth data (cartography, radar imagery, fishinder imagery, SiriusXM Marine Weather/Satellite Radio, and IP camera video) will be shared with other a/c/e/eS/gS-Series MFDs via an Ethernet network. The "Network" port of each a/c/e/eS/gS-Series MFD is accordingly designed to be interfaced to a HS5 RayNet Network Switch or directly to a compatible device having an Ethernet communications interface (ex. a/c/e/eS/gS-Series MFD, Digital/HD/SuperHD Digital radar device, CP100/200/370/470/570 Fishfinder Sounder Module, etc.) via an appropriate length of RayNet (F) to RayNet (F) Cable or Digital Radar Cable.

Each Ethernet Network socket of the Data Master MFD may be tested by unplugging the RayNet cable which has been interfaced to the SiriusXM Satellite Weather/Radio Receiver or Network Switch from the MFD's Ethernet Network socket, connecting it to the second Ethernet Network socket, and then re-testing the MFD's ability to access SiriusXM Marine Weather Data. Should one of the Data Master MFD's Ethernet Network socket be found to not be operational, then the Data Master MFD will need to be serviced by Raymarine’s Product Repair Center.

Should both of the Data Master MFD's Ethernet Network Sockets be determined to be operational, then it is recommended that the Ethernet communications path from the Data Master MFD to the symptomatic repeater MFD(s) be inspected to ensure that the RayNet (F) to RayNet (F) Cables are securely connected (i.e. re-seat and ensure that the locking rings have been rotated into the locked position) have not been damaged, modified (ex. spliced), or subjected to a bend radius less than 3" (tighter radius bends may result in permanent damage to the cable). Any RayNet cables found to not meet these criteria should be replaced. Should the RayNet cables be found to meet these criteria, then the RayNet Cable should be disconnected from the symptomatic MFD's Ethernet Network socket, connected to the symptomatic MFD's second Ethernet Network socket (if any), and re-tested. Should the problem abate, then the symptomatic MFD may be used in this configuration, but should be sent to Raymarine’s Product Repair Center prior expiration of warranty. Should the problem persist, then the symptomatic MFD should be sent to Raymarine’s Product Repair Center.
