Blink Codes - Garmin GSD 20 Installation Manual

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.
