FIGURE 5–2: 485P Option with RS-485 Communication Installation

RS485 allows you to connect one or multiple EPM6000 meters to a PC or other device, at
either a local or remote site. All RS485 connections are viable for up to 4000 feet (1219.20
meters).

FIGURE 5–3: EPM6000 Connected to PC via RS485

As shown in Figure 5.3, to connect a EPM6000 to a PC, you need to use an RS485 to RS232
converter.

Figure 5-4 below, shows the detail of a 2-wire RS485 connection.
