Operating Manual
EBUW 232 A
EASY BUS - protocol converter and alarm supervisory device
1 General
The EBUW232A includes two functions in one device - protocol conversion and alarm supervision.
1.) The EBUW is a protocol converter which rebuilds splitted RS232 protocols (e.g. splitting done by a MODEM) and
makes the protocol conforming to the EASY BUS timing requirements again.
2.) The EBUW232A automatically scans one EASYBUS module each 500 ms and *hecks it for alarm conditions. If
an alarm is present the alarm output of the EBUW will be activated. Additionally there is the possibility to connect a
s*****i*g module EBB4out.
2 Installation Instructions
The EBUW232A has just to be inserted between the EASY BUS converter and the requesting device (MODEM, PC,
)
by means of the adapter cable.

If just used as protocol converter, no additional power supply is necessary, the device taps from the RS232 voltages
of the requesting devi*e. If *sed for a***m supervision an external power supply should be connected to the cable
marked with ‘Versorgung‘ i.e. supply because the supply from the RS232 interface may not be sufficient. Note:
Using devices with weak RS232 signals (e.g. some laptops) an external power supply may be even necessary when
used as simple protocol converter.
The alarm output is available through the cable "Alarmausgang" i.e. “alarm output“ of the adapter cable.
