BUS ADDRESS
Defines the address of the Spider unit (lowercase or uppercase letter) on the RS-485 bus.
Caution: When the configuration is changed, the Spider must be power-cycled
in order to re-scan the sensors. Disconnect the Spider from power
(both the external adapter and the RS-485 line powered from the Poseidon)
and then reconnected power again.
Spider detects 1-Wire probes only when powering up. When no 1-Wire probe is detected at
that time at a particular input (1 to 4), Spider acts according to DIP4 setting:
o1-Wire probe not found, DIP4=Off: Probe assumed to be a dry contact (Switch) [s]
o1-Wire probe not found, DIP4=On: No probe detected
Probe and dry contact scan starts at input 1 and ends at input 4.
Addresses 1–6 are assigned in the order in which the probes are found. Addresses are not
bound to input connectors.
oFor example, if a single probe is connected to input 4 (and DIP4=Off), it will get the
address shown in column 1.
oCombined sensors (temperature/humidity with a single RJ11 jack) are assigned two
sequential addresses (1+2, 2+3, 3+4 and so on).
Note: For clarity, we recommend to set DIP4=On at all Spiders with no dry contacts
connected. Otherwise, unused inputs are assumed to have Dry Contacts connected
to them and are detected as such.
