Hello! Thank you for contacting us! To update the firmware via WiFi, the IS20 must first be connected to a router with an internet connection. If you try to update the firmware without connecting the IS20 to the Internet, the error message “Firmware Verification Failed: 52” will be displayed.

I am trying to update the firmware on a IS20 showing Firmware version V2.00.230731 (1939).  When I try to do it via WiFi I get a Check Firmware Failed: 52.  Not sure what the means. When I try to update it via usb the process of connecting the unit to my windows computer via USB and then pressing the power button for 2 seconds followed by the OK button seems to do nothing.  The IS20 just starts ups as usual.

We are sorry to hear that you are experiencing this issue with your device. Is there a way you could check the VSWR value and email it to us, please? Also, could I ask, how long is the cable which is connecting the transponder to the splitter? Do you have another cable you could try (preferably a longer cable) to see if there is any change? Thank you ..read more

After many tests I realize that I have purchased the wrong device. Even when immobilized, the heading output varies within a range of about 5 degrees, continuously. This cannot drive an autopilot, independently from the issue of the update frequency. I realize now that I have purchased the wrong product, because for my purcpose I should have purchased your other product:  Quark-Elec AS08 This product will be more than perfect for driving my Raymarine smartpilot.  I have got AS08 in hand now, but it won’t talk to my Smartpilot S3, any idea?     ..read more
