LED status
The LEDs light according to equipment status as follows:
CR2: Lights when receiving NMEA data from J2.
CR3: Lights when sending NMEA data from J3.
CR4: Lights when sending NMEA data from J4 to J9.
CR6: Blinks every second.
CR7: Lights when ROM error is detected, or no signal at J2 for 300 ms.
CR8: Lights when RAM error is detected, or no signal at J3 for 300 ms.
CR9: Lights when SIO error is detected, or NMEA data is input at J2.
CR10: Lights when NMEA data is input at J2.

Beacon : 283.5 325.0kHz
Loss GPS : 4dB
Beacon : 3dB
Power supply to antenna One line fed from two distribution lines
Connector type TNC
Ambient temperature -15 to +55

Note: Furuno GPS Receivers are designed, considering 10dB antenna cable
loss. Because this distributor loses 4dB, shorten antenna cables so that
loss is 6dB or less.
Refer to the following formula for calculation of loss.
8D-FB cable: 0.165dB/m
3D-2V cable: 0.65 dB/m
For the mounting, see the outline drawing at the back of this manual.
