Using The Rs485 To Usb Communication Converter - Electro Industries Shark 200 Installation & Operation Manual

The Unicom 2500 can be configured for either 4-
wire or 2-wire RS485 connections. Since the
Shark® 200 meter uses a 2-wire connection,
unless you are using the RS485 4-wire to 2-
wire communication cable available from
EIG's online store, you will need to add
jumper wires to convert the Unicom 2500 to the
2-wire configuration. As shown in Figure 5.6,
you connect the "RX-" and "TX-" terminals with a
jumper wire to make the "-" terminal, and con-
nect the "RX+" and "TX+" terminals with a
jumper wire to make the "+" terminal. See the figure on the right for the Unicom
2500's settings. The Unicom's Baud rate must match the Baud rate of the meter's
RS485 port: you set the Baud rate by turning the screw to point at the rate you want.

5.1.2.2: Using the RS485 to USB Communication Converter

EIG offers an RS485 to USB converter to facilitate communication between meters
with an RS485 port and a device with a USB port, e.g., a PC. Utilizing a driver down-
loaded from the EIG website, the USB operates as a virtual Com port, allowing a user
to communicate with the meter as with a standard PC serial emulation port.
The converter's model number is E205301, and it can be ordered from EIG's web-
store: www.electroind.com/store.
