Neets Control LiMa Installation Manual page 9

Relays
Relays are used when a external control is needed where there must be
potential free connection between the control and the LiMa.
The relays are normally open types. This means that the terminals are not
connected when the relay is off.
RS-232 Connectors
The onboard RS-232 ports T1 + R1, T2 + R2 can be used for two-way
communication with external RS-232 compatible devices. Alternatively all
Tx ports can act as IR transmitter ports.
All of the RS-232/IR ports can be configured in the Neets Project Designer
software either as RS-232 or as IR emitter.
