7.4 Wiring
7.4.1 Wiring Specifications
The PODD and connected hardware should all be compatible with the following spec:
RS-485 (4 wire) standard – defines the necessary electrical characteristics of
cabling, transmitters and recievers. All Alencon devices, including the PODD, have
internal hardware compliant with RS-485.
STP Cat5e (or better) cable – other RS-485 compliant cable types can be used,
but Cat5e is most common. Note that Cat5e cables will have a max run length of
100m.
RJ45 T-568B connector – all communications ports on Alencon devices accept
male RJ45 connectors as input.
7.4.2 Wiring Configurations
Single PODD Configuration:
Connect a cable between the Modbus RTU port on the PODD and the Alencon
devices. All Alencon devices can be daisy-chained together.
Connect the RJ45 termination dongle to the final Alencon device on the Modbus
RTU daisy chain.
For Wired: Connect a cable between the WAN port on the PODD and a nearby
Ethernet switch.
For wireless: Connect the purchased antenna to the adapter on top of the PODD.
Multiple PODDs Configuration:
Distributed PODDs: All distributed PODDs will be setup identically to the single
PODDs outlined above.
Centralized PODD: Use the WAN port to connect the PODD to 24V power and a
network switch (see section 7.5.2).
If setting up a wireless Central PODD, an additional connection between the LAN
port on the PODD and provided MicroTik access point is required.
