PHYSICAL LAYER
The EPM6000 meter is capable of using RS-485 as the physical layer. This is accomplished
by connecting a PC to the EPM6000 with the RS-485 connection on the back face of the
meter.
RS-485
RS-485 provides multi-drop network communication capabilities. Multiple meters may 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.
Communication Parameters
EPM6000 meters communicate in DNP 3.0 using the following communication settings:
• 8 Data Bits
• No Parity
• 1 Stop Bit
Baud Rates
EPM6000 meters are programmable to use several standard baud rates, including:
• 9600 Baud
• 19200 Baud
• 38400 Baud
• 57600 Baud
