RADIUS+ /195M (TNB)
USER’S MANUAL
Revised: 30 Jan 2018 1 of 10
Overview
The ESTeem Model Radius+/195M (TNB) is a wireless system combing an intelligent, self-monitoring Radus+
amplifier with the ESTeem Model 195M, VHF (150-174 MHz) wireless product. The Radius+/195M (TNB) system will
increase the output power of the 195M to 25 Watts for long distance, outdoor applications. The amplifier requires
no additional programming for operation but has the ability to monitor forward power, reflected power and internal
temperature through either an Ethernet or serial (RS-232) interface.
The ESTeem Radius+/195M (TNB) system can be used to build many types of Wireless Local Area Networks (WLAN).
The radio system has multiple serial (RS-232, RS-422 and RS-485), Ethernet and 4/20mA sensor interfaces. The
Radius+/195M (TNB) system can be configured for multiple modes of operation depending upon the needs of the
wireless and wired network. The following interface configurations are provided as an overview of the basic network
types, as all possible network configurations cannot be listed. For further help in selecting the correct network type,
please contact Customer Support at 509-735-9092.
Serial Applications
A Radius+/195M (TNB) system can be configured for point-to-point, multipoint or PLC emulations through software
configuration changes. The following are brief descriptions of the Serial Device Interface (SDI) configuration modes.
RS-232 – The ESTeem 195M has two (2) RS-232 data ports. The primary RS-232 port (Port 3) has full hardware
handshaking through the request to send (RTS) and clear to send (CTS) lines. Both RS-232 ports are software
configurable from 2,400 to 115,000 bps.
RS-422 – The ESTeem 195M has a single RS-422 data port (Port 2). The RS-422 data port is shared on the front panel
with the 10/100 Mbps Ethernet interface. The RS-422 interface is typically used for long distances to 4,000 feet at
bauds rate software configurable from 2,400 to 115,000 bps.
RS-485 – The 195M radio has a single, two-wire RS-485 data port (Port 1). The RS-485 data port is shared on the front
panel with the 4/20mA sensors. The RS-485 interface is typically used for long distances to 4,000 feet at baud rates
software configurable from 2,400 to 115,000 bps.
Ethernet Applications
The ESTeem 195M has a 10/100 Mbps Ethernet interface (Port 2) that is used as both a data port and the primary
programming port. When the Ethernet port is used as a data port there are two modes of operation. The primary use
will be as a slow speed (12.5 Kbps) Ethernet bridge to remote locations to gather data from remote Ethernet devices.
The secondary mode of operation is to configure the Ethernet port as a TCP or UDP Socket and write custom software
applications to access the data port.
Sensor Applications
The ESTeem 195M has four (4) 4/20mA sensor inputs. The sensor inputs can be read out of the Radius+/195M (TNB)
system though their ModbusTCP address, a software command or the Model 195M/H/C configuration utility.

Programming
The Radius+/195M (TNB) system uses the same ESTeem Narrowband Configuration Utility for configuration and
monitoring as the ESTeem Model 195M by itself.
The ESTeem Narrowband Configuration Utility (a component of the ESTeem Discovery Suite) will allow easy access
to the configuration, monitoring and diagnostics for the Radius+/195M (TNB) system.
Installation
The Discovery Suite can be downloaded from the ESTeem web site
(http://www.esteem.com) or is available on the Software Resource media that
was shipped with the radios.
1. The Discovery Utility is a Java™ based application compatible with any
computer operating system (Window, Linux, etc). The application requires
two (2) additional support files to operate:
Java – Downloadable from http://www.java.com. The version required will be based upon your operating system.
Note: The installation and updates from Java may try and install additional web browser toolbars. Uncheck the
optional installation if they are not desired.
WinPcap – Downloadable from http://www.winpcap.org/. The version required will be based upon your
operating system.
Figure 4: ESTeem Discovery Utility
2. Once both the above programs have been installed, save the ESTeem.exe file to any location on your
computer such as the Desktop. Double click the ESTeem.exe program and Figure 2 will be displayed.
3. Connect the Radius+/195M (TNB) system to your computer either directly to the Ethernet card or through a
Switch using a CAT-5e Ethernet cable. The Ethernet port supports Auto-Negotiation, so either a patch cable
or crossover cable will work. Press the Discover EST Radios button. This discovery utility and imbedded
ESTeem Narrowband Configuration Utility will be used throughout the remainder of the User’s Manual.
4. The ESTeem 195M will be displayed (Figure 5). If the ESTeem is not on the same IP subnet as the computer,
double click on the IP, Netmask or Gateway and make the necessary changes. Press the Apply Changes
button when complete.
Technical Tip: If your computer is
configured for DHCP and not
attached to the network, you will
need to assign a static IP address to
program the Radius+/195M (TNB)
system.

5. If changes were made to the IP address, you will need to press the Discover EST Radios button again to show
the changes. Right-mouse click on the radio and select Configure Radio button to begin programming.
Figure 6: Opening Radio Configuration Software
195M Configuration Page
The Configuration Page is the default page entered
when the 195M Configuration Utility is opened. If
the utility was opened through the Discovery
program, the current configuration parameters for
the modem will be displayed (Figure 7). If the 195M
information is not displayed, press the Read Config
button to continue.
The majority of the radio’s configuration can be
entered from the Configuration tab. Setting the
modem’s address, destination, frequency, port
settings and operating mode are all available from
this single page. Any changes made on the
configuration menu will be saved to the listed 195M
when the Write Config button is pressed.

Using Utility Program
The ESTeem Narrowband Configuration Utility will open on a Radius+ amplifier to the command console menu
(Figure 8). This direct interface to the Radius+ will display status information such as the forward and reflected
power ratio and allow modification of the software commands.
Figure 8: Utility Console
Firmware Updates
The Radius+ amplifier can update the firmware through the utility if new features for updates are added in the
future. Select the to the Firmware tab and press Update Firmware button to complete. If the firmware version is
up to date the message in Figure 9 will be displayed.

Operational Monitoring
When the Radius+ amplifier is in normal operation, the console will output the forward and reflected power ratio
for every transmission in the following format:
fwd/rev ratio, 1815.7
fwd/rev ratio, 1210.0
fwd/rev ratio, 930.3
fwd/rev ratio, 1632.6
fwd/rev ratio, 490.5
fwd/rev ratio, 577.0
fwd/rev ratio, 708.2
The ratio number will change based upon hardware conditions, environmental conditions and overall power
output, but the ratio number is not directly related to a percentage or power value. It is best used as a long term
indicator of the heath of the transmission system. As the number approaches 0 (lower ration numbers) the higher
the reflected power is detected. There is a software command (reflect – see below for full details) that will set a
minimum acceptable ratio before the Radius+ stops amplifying the RF energy for self-preservation.

The command sets the ID field for the amplifier. This can be set to any alphanumeric value such as site name, location or
serial number. This value will be displayed in the Discovery Utility under ID (see figure 6)
pcbtemp
This command will measure the internal temperature of the Radius+ amplifier. The temperature will be displayed in both
Celsius and Fahrenheit.
reflect (0-2000)
This software command will set the maximum reflection threshold before the amplifier will stop operation. The ratio number
will change based upon hardware conditions, environmental conditions and overall power output, but the ratio number is

system. As the number approaches 0 (lower ration numbers) the higher the reflected power is detected. If the reflect
command is set to 0, this feature will be turned off.
