Baud Rate Setting
When setting the gyro in "● Heading Equipment Setting", the setting of the baud rate is
not required.
Connecting to External Buzzers
When connecting an external buzzer to the NSK unit, read the following guideline.
TB40 of the built-in PCB CSC-631 has a dry contact output, so that if the connection
"TB40 → Power Supply → Positive terminal of the buzzer → Negative terminal of the
buzzer → Power supply ground" is made, then a buzzer can be sounded when there is an
alarm from the JMA-3300.
Refer to "3.11 CONNECTING CONTACT SIGNALS TO EXTERNAL
BUZZERS/EXTERNAL DEVICES" for connection of external buzzers, and set
"3.11 CONNECTING CONTACT SIGNALS TO EXTERNAL BUZZERS/EXTERNAL
DEVICES" - "■ Jumper setting".
Example of connection
Note:
The maximum contact capacity is:
