Blink Codes

Once the unit is installed, it switches on when the display unit is

powered on (or the GSD remote power line is pulled low, with power

applied). The two-color (Green/Red) LED on the GSD 20 indicates the

current operational status of the module. Codes are:

Code: Green blinking, on for 1 second, off for 1/2 second (slow

blink)

Status: GSD 20 is connected to one display device and is operating

properly. User should see sonar data on the display unit.

Code: Green blinking, on for 1/2 second, off for 1/4 second (fast

blink)

Status: GSD 20 is connected to two display devices and is operating

properly. User should see sonar data on both display units.

Code: Red blinking, on for 1 second, off for 1/2 second (slow blink)

Status: GSD 20 is powered on but is waiting to connect to a display

device. In this state, the GSD 20 does not transmit any sonar signals

and is not sending out any sonar information to display units. If a

display unit is connected, check the wiring if this code persists.

Code: Solid Red (no blink)

Status: Software failure - Call Garmin Customer Support. If the

cause is a software error, the display unit can show the error. Power

must be cycled to clear the error.

Code: Red blinking, on for 1/10 second, off for 1/10 second (very

fast blink)

Status: System alarm. The display device gives a message indicating

the type of failure. After the alarm condition is ﬁ xed, power must be

cycled on the GSD 20 to clear the alarm.
