Figure 2.1 24VDC Power Supply Connection
If the EIA-485 port will be used for Modbus RTU communication, RLE Technologies
recommends an 18AWG shielded twisted pair stranded copper wire for the connection, using
no more than 2000 feet (609.6m) of wire at this specification. If longer runs are needed, please
contact RLE Technologies.
The Wireless Gateway is shipped with a 418 MHz, 6-foot cable antenna and a 916 MHz,
6-foot cable antenna. The 418 MHz antenna has longer shafts; the 900 MHz antenna has
shorter shafts. Plug each antenna into its appropriate jack on the front of the Wireless
Gateway.
