devices (not including POWER LEADER Repeaters
and Junction/Outlet Boxes).
The device shall provide RS485 input and output ports
with adjustable baud rate (1200, 2400, 4800 and 9600
baud, and 19.2 Kbaud) for communications on a
Modbus RTU protocol network.
The device shall have a four-character alphanumeric
high-contrast LED display and a four-key keypad on its
faceplate.
The device shall require control power of 85-265 volts
ac or 100-250 volts dc.
