Software Features

  • Pole Mounting.  Remote pole mounting greatly reduces the 195H’s installation cost while increasing wireless performance.
  • Protocol Emulations. Protocol drivers for most major PLC manufacturers are included with these industrial radios. This protocol emulation allows transparent operation of the controllers without impacting the 195H unit’s ability to use any remote location as a repeater.
  • Multiple Repeaters.The 195H supports multiple repeaters in a single network.
  • Multiple Modes of Operation. For additional flexibility, Model 195H serial/Ethernet radios can function as Master, Remote, Repeater, or Remote/Repeater nodes.
  • Spectrum Analyzer. The 195H and Software Configuration utility provide a full feature spectrum analyzer for the 217-220 MHz frequency band.

Wireless Ethernet and Serial Ports

The ESTeem Model 195H industrial wireless router is the perfect radio solution designed for the rigors of the Industrial, Public Safety, and Federal markets when the VHF band is needed for terrain coverage.

These narrow band-compliant VHF radios operate in the 217-220 MHz frequency band and provide Ethernet, Serial RS-232C, RS-422, RS485 and 4 Channel Sensor Interface in a single wireless modem. The 195H industrial wireless router can cover distances greater than 10 miles in high noise environments depending on the antenna used. For added flexibility, the 195H is downward compatible to the ESTeem Model 192M/MHP series. You can create wireless networks over large geographical areas by using the internal Digi-Repeating feature, which makes all remote locations possible repeater sites.
