PHYSICAL LAYER
The IQ 150S meter can use RS485 as the physical layer. This is accomplished by connecting a PC
to the meter using the meter’s RS485 connection (see Chapter 5).
RS485
RS485 provides multi-drop network communication capabilities. Multiple meters can be placed on
the same bus, allowing for a Master device to communicate with any of the other devices.
Appropriate network configuration and termination should be evaluated for each installation to
insure optimal performance (see Chapter 5).
