Remote your RS-485 or RS-422 device
WILDR-MIU provides a wireless RS-485 / RS-422 interface port for applications that require wireless connectivity. This interface is capable of speeds ranging from 4.8 to 115.2 kbps. Maximum RF output power is 20.8 dBm which translates to a range of about 250′ indoors (depending on building construction and material composition), and 1-mile outdoors. FCC certified. As shown in the figure below, the RS-485 is a 5-position screw-down terminal block connector.
A laptop or a PC running a serial communication program such as Microsoft Windows® Hyperterminal® is connected to the console port via a serial cable, or a DB-9 to USB cable (provided) for initial radio configuration. The Console port is used to configure the wireless radio parameters such as frequency channel, data rate, and interface. There are a variety of tools built-in the firmware to assist in configuring the radio in the field. These tools can be used to measure RF channel noise so the installer can select a clean channel. Also, the radio can be put in test mode where a constant carrier, or a modulated carrier is transmitted continually to facilitate range-finding.
Each data packet is encrypted using a random key per packet. Keys are not transmitted in the payload, therefore capturing the packet by a third party is not a security risk. For added security, there is also a three character code selected by the user that makes the encryption specific to the site. All standard keyboard characters are allowed with the exception of function keys. This feature does not allow radios from other sites to function in your site.
The radio is supplied with complete documentation that includes a quick-start manual, and user reference manual. For more information and the radio RF characteristics please see the Resources tab.
