Precautions for Installation
1) Supply voltage
JAX-9B operates within the following voltage range shown below.
• DC power supply: +10Vdc to +42Vdc
(Standard voltage: +12Vdc, +24Vdc, +32Vdc -10% to +30%)
• AC power supply:
100Vac / 220Vac, Selectable by connecting to terminal pins
(Option) Output voltage is +24Vdc.
Input range 100Vac to 120Vac ±10%, 50 / 60Hz ±5%
200Vac to 240Vac ±10%, 50 / 60Hz ±5%
NOTE •When not using AC power supply (option), connect cables after confirming the voltage
between FG and the minus terminal of DC power supply is 0V.
2) Selection of FUSE
The capacity of a fuse available to JAX-9B varies depending on the supply voltage. JAX-9B is equipped
with 5A fuse at the factory. Select a proper fuse (among replacement fuses) according to the supply
voltage and set it in the fuse holder.
The fuse holders are next to the power switch on the rear of JAX-9B.
• +12Vdc power supply: Use an 8A fuse.
• +24Vdc power supply: Use a 5A fuse.
• +32Vdc power supply: Use a 5A fuse.
3) Compass Safety Distance
JAX-9B should be within a compass safety distance of 0.7m.
4) BK signal
BK signal drives the relay of JAX-9B which controls the antenna line.
The relay of JAX-9B is driven by +24Vdc. Connect the BK signal to JAX-9B after confirming the voltage
of BK.
5 ） When using existing equipment
When connecting existing equipment that has already been in use inboard such as antennas and external
receivers, etc., connect them to JAX-9B after confirming the result of single-equipment operation is normal.
(Whether or not it is damaged and it starts up with power supply, and insulation check, etc.)
