Overview
The ESTeem Model /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 /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 /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
/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 /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 /195M (TNB)
system though their ModbusTCP address, a software command or the Model 195M/H/C configuration utility.
