TERMINAL
DESCRIPTION
Input signal (+) to Slave. Only connected when DB Unit
is configured as ‘Slave’.
IN+
[1]
Input signal (-) to Slave. Only connected when DB Unit
is configured as ‘Slave’.
IN-
[1]
Output signal (+) to Slave. In this case, DB Unit can be
configured as ‘Master’ or ‘Slave’.
OUT+
[1]
Output signal (-) to Slave. In this case, DB Unit can be
configured as ‘Master’ or ‘Slave’.
OUT-
[1]
