Assignment of transmitters to the receiver
(linking)
A receiver can display and process data from up to 16 transmitters. Each transmitter must be
linked with the receiver. Three linking methods are available:
- On the device using a list of received, non-linked transmitter IDs or by directly entering the
transmitter ID
- Using the setup program, and
- Via the RS485 interface by Modbus commands.
The list of received, non-linked transmitter IDs is automatically saved by the receiver. The trans-
mitter IDs are automatically detected in this list (max. 25 entries); then they are entered and de-
leted. The transmitter ID can be directly entered at the device or with the setup program. The
transmitter IDs can also be set from a Modbus master (e.g. PLC) via the RS485 interface at any
time.
Open air range
The open air range is 300 m. To achieve this max. receiving quality and to achieve an optimum
adaptation of the lambda/4-antenna, use the antenna wall holder with the 3 m antenna cable
(available in the accessories). When installing the antenna directly on the receiver, a reduced
range of approx. 40 % must be taken into account. The transmission range may be additionally
reduced by buildings, concrete ceilings, walls, and other structural works.
