Operation RWR95.50

2.4 Assigning the Touch Probe ("Synchronisation Mode")

Every receiver RWR95.50 is capable of managing the addresses of three bidirectional probes (probe configuration

A/B/C). These probes are assigned in "Synchronisation mode" via the integrated IRDA interface. The address of the

receiver is uniquely assigned to the probe and the address of the probe to the receiver.

Should another probe be assigned the same probe configuration (A/B/C) as a probe already assigned at a later time,

then the address of the probe first assigned is deleted in the receiver and the address of the new probe is saved.

Synchronisation mode is started by the probe and the precise procedure for assignment is described in the operating

instructions for the probe.

With mono-directional activation, the address of the probe is also assigned to the receiver in "Synchronisation mode".

Any number of mono-directional probes can be operated by only one receiver. They only have to be synchronised

once with their first use and are automatically detected by the receiver with subsequent use.

2.5 Automatic Frequency Assignment for Data Transmission

Blocking of Faulty Frequencies:

Providing the receiver is in "ERROR" status (no active connection between the touch probe/receiver), the receiver

checks the environment for radio interference and evaluates the available frequencies in terms of their suitability for

communication with the touch probe (signal quality). This enables all radio interference to be detected within a short

time. Should a touch probe now be activated bidirectionally or should a mono-directionally activated touch probe

issue a communication request, then the receiver assigns it to a transmission frequency with as small an interference

range as possible.

Release of Frequencies:

If it is in "ERROR" status (no active connection between the touch probe/receiver), the receiver continues to always

check the environment and constantly evaluates the frequencies. Therefore with new or additional communication

requests, frequencies previously classified as poor can also be assigned, as the environmental situation

(interference) has now been able to be improved.
