DIP switch, jumper wire settings
Default setting
The default setting of all DIP switches is off and all jumpers wire are set to “#1.” (Note that jumper wire JP1 is set at #1, #2, and #3.) In those settings the gyrocom- pass having the following characteristics can be directly connected; modification of the GYRO CONVERTER Board is not necessary.
AC synchronous signal: 50/60 Hz
Rotor voltage: 60 V to 135 V AC
Stator voltage: 60 V to 135 V AC
Gear ratio: 360x
Supply voltage: 30 V to 135 V AC
If the specifications of the gyrocompass differ from those mentioned above, change jumper wire and DIP switches settings on the GYRO CONVERTER Board. Set- tings may be changed according to gyrocompass specifications or make and model of gyrocompass (see page
