A57D external alarm capability
current system:
mfd A57D located at nav station
transducer P79 in hull
no network
mfd supplies gps location to vhf 0183 from power/NMEA cable
this is a stand alone back up system to my primary system, it is my intent to keep these 2 systems separate in case there is a failure in either system

question 1) is there a way to connect an external alarm buzzer or audible device at the helm with out developing a seatalkng network for that sole purpose?

question 2) will a seatlkng network allow for a external alarm?

goal: back up to shallow water alarm on primary system at the helm

searched "external alarm A57D" got nothing

thank you

RE: A57D external alarm capability
Welcome to the Raymarine Forum Bucky,

Unlike the more capable E-Series Classic MFDs of this period, the A-Series Classic MFDs did not feature an alarm port/cable. While Raymarine recently introduced the A80614 Seatalkng Auxiliary Alarm Buzzer, this accessory is not designed to sound for alarms generated by a MFD. The Seatalkng Auxiliary Alarm Buzzer is designed to sound for alarms for autopilot systems, instruments, AIS receivers, and NMEA2000 engine monitoring systems. As indicated within its title, this product is designed to be interfaced as a spur to the system's powered and properly terminated SeaTalkng / NMEA 2000 backbone.
