APPENDIX C
MODEL 192 INTEGRATION
Revised: 15 Feb 2017 APX C-1 ESTeem Models 195MHC
Model Series 192 Integration
The ESTeem Model 195M and 195C were designed to be downward compatible
with the legacy ESTeem Model 192 series of wireless modems. The Model 192
series had been in production since 1996 with several generational changes in the
product lifespan. The manufacturing variations throughout this time require that
a new ESTeem Model 195M/C be “trained” to communicate with an existing Model
192 network. This training process (described below) will allow the Model 195M/C
to recognize any change in deviation in the older radios and adjust accordingly.
If an ESTeem 195M/C is added to an existing Model 192
network, it is highly recommended the Model 195M/C
is installed at a remote location and not the Master or
Repeater location of the Model 192 network (Figure 1).
If the 195M/C is required to be used as the Master or
Repeater site, “train” the radio modem to one of the
remote locations and then test all wireless links from
that location.
The Model 195M/C configuration utility can be used to
provide local signal strength (RSSI) information but
cannot gather information from a Model 192 because
the process uses ModbusTCP protocol only available in
the 195M/C. The ESTeem Model 192 configuration
utility’s diagnostic can be used to test the operation of
the wireless network but must be run from the Model
192 side of the wireless network. For example in Figure
1, the diagnostic utility (Polling Test) must be run from
the Master SCADA location.
Loading Model 192 Compatibility Firmware
The ESTeem Model 195M and 195C will need to load the firmware version compatible with the Model 192 series
(201605311302). This firmware version and utility are available within the ESTeem Discovery suite program. To select the
Model 192 compatible utility, Discover the radio as described in Stating Out – Chapter 2. Select the Model 195M or 195C that
will be used in the network by clicking on the IP address (the line will turn blue) then press the Tools Menu and select “195cm
Narrow Band Configuration Tool (Legacy 192)” to open the Model 192 compatible Utility. Figure 3 will be displayed.
Technical Tip : The ESTeem Model 192
network MUST be configured for narrow
band (12.5 kHz) operation before Model
195M/C integration.
