The alarm signals are outputs used to signal that the radio units has detected an alarm internally. The
Select signal is used to select or deselect (inhibit) a particular unit. By deselecting a unit, the unit will
enter into standby and can not be used for radio communication. However, all other functionality of
the radio units is operational when the radio is in the standby state.
The pinout and signals are equal on the transmitter and the receiver unit, except the ALARM (REM,
p.7) pin. This pin has a fixed +5V pull-up on the receiver, while the pull-up is configurable on the
transmitter.
