5.5 Setting up the Receiver
Refer to
Figure 13
above for the location of the setup switches. Check that the
Tx/Rx link connections are set correctly. Refer to the table in section
5.3.2
above
for details on links and
Figure 12
on page
29
and
Figure 13
above, resp., for the
location of the links.
5.5.1 Bus Termination Switch (SW101)
The Bus Termination switch (SW101) setting is determined by the sensor’s
position in the network. Set the switch to
U (unterminated) for all sensors
connected in a chain (‘daisy chain’), except the last sensor, which must be set to
T (terminated). For spur-linked systems, all sensors should be set to T
(terminated).
5.5.2 Set Address Switch (SW201)
Each sensor must have a unique address on the network. The address is set by
means of the DIP switch (SW201). Only switch positions 1 to 6 are used, giving
valid address settings from 1 to 64. The address switch uses binary coding to
calculate the required address.
Example – To set address no. 5: set switch 1 (binary 1) ON and switch 3 (binary
4) ON (4+1=5). The above illustration shows address 5.
