3.2.6.1 Daisy-Chaining Power to Multiple Base Radios
A consideration when daisy-chaining power to multiple Base Radios is the power draw at
power supply. Each Base Radio will typically draw 200mA @ 24VDC. This means a
single Base Radio will draw a typical average power of 4.2W.
If using the supplied DIN rail mounted 15W power, it is suggested that no more than
three Base Radios be tied parallel to this supply.
To daisy-chain two or more Base Radios together, each Base Radio should be wired in
parallel to the next while making sure power is not supplied from two separate supplies to
any single Base Radio. A typical wiring setup is shown in Figure 3-7 below:

3.2.6.2 Daisy-Chaining RS-485 to Multiple Base Radios
Modbus connections can be daisy-chained together, but WMT connections cannot. There
can only be one Base Radio, multiple Output Modules, and a PC on the same WMT RS-
485. If you have two Base Radios connected to a PC running WMT, you must have two
COM ports.
