Profanity Delay Control
A profanity delay unit can be attached and controlled to the unit via this interface. The
control is achieved using a relay. Each function has an input pin and two possible output
pins. The relay can be congured to complete the circuit and route back the input signal
either normally open or normally closed, depending on which output pin is used. The
interface is 9 pin male D-type.

Serial Ports
There are two parallel serial ports on the back of each unit to enable the connection of
multiple RB-OA3 units. These use standard RJ-45 connectors.
When connecting multiple RB-OA3 units together, simply connect these ports together.
If you have more than two RB-OA3 units, multiple connections can be made to ensure that
all units communicate even if one connection is lost.
