Software Features

  • Pole Mounting. Remote pole mounting allows the 195M to greatly reduce the installation cost and increase wireless performance.
  • Protocol Emulations. The 195M industrial wireless router has protocol drivers for most major PLC manufacturers, providing transparent operation of the controllers while at the same time enabling the 195M to use any remote location as a repeater.
  • Multiple Repeaters. Not only can any remote 195M be used as a repeater, but the model also supports multiple repeaters in a single network.
  • Multiple Modes of Operation. Our Model 195M Ethernet/serial radios can function as Master, Remote, Repeater, or Remote/Repeater nodes for added flexibility.
  • Model 192 Series Compatibility. The 195M is downward compatible to operate as a remote in a serial network with the ESTeem Models 192M or 192MHP.
  • Spectrum Analyzer. The 195M and Software Configuration utility provide a full feature spectrum analyzer for the 150-174 MHz frequency band

Wireless Ethernet and Serial Ports

The ESTeem Model 195M is the perfect industrial wireless solution for a wide range of modes of operation, including wireless Ethernet bridge, point-to-point networking, point-to-point wireless bridge and remote repeaters.

We engineered these Ethernet/serial radios specifically for the rigorous Industrial, Public Safety, and Federal markets when terrain coverage requires the VHF band. With the 195M industrial wireless unit, you have access to Ethernet, Serial RS-232C, RS-422, RS485 and 4 Channel Sensor Interface, all in a single modem.

A narrowband-compliant licensed radio, the Model 195M provides downward compatibility to the ESTeem Model 192M/MHP series and delivers reliable communications over distances greater than 10 miles in high noise environments, depending on the antenna deployed. Because the Model 195M’s internal Digi-Repeating feature creates possible repeater sites out of all remote locations, you can use these serial radios to establish wireless networks over large geographical areas.

Whether you require a wireless Ethernet bridge or downward compatibility with older ESTeem serial radios, the Model 195M provides the reliable communications you need. Review the literature below and then be sure to contact us for the industrial wireless devices to solve your most difficult communications challenges.

Supporting Information

Latest 195M Firmware Version

*Current Firmware Release: 201706051427, Release Date: June 21, 2017
*This latest firmware release for the 195 Narrow Band radios increases the Routes and Append tables to 64 entries.  This increase was done provide for larger wireless Ethernet networks.  Updating the firmware will not corrupt the radio’s configuration.  Use of this utility version will not allow reading or saving program files from older firmware versions, until the radio’s firmware is updated.  If you have older firmware installed in radio and need to read or save the configuration, use the Legacy Discovery Suite and Configuration Utility below.
Current Legacy 192 Compatibility Firmware Release: 201605311302, Release Date: November 22, 2016
For instructions on how to update the modem, please contact ESTeem Customer Support at 509-735-9092 or follow the procedure in the User’s Manual.  Both firmware updates are contained in the ESTeem 195 M/H/C Configuration Utility which can be found an the following location.  No additional downloads are required.

Legacy Discovery and Configuration Utility

The following Discovery and Narrow Band Configuration can be used to read and save configuration files in firmware versions older than 201703241206.  This will allow backup of the configuration prior to completing the latest firmware update above.
