CHAPTER 1
INTRODUCTION
Revised: 15 Feb 2017 1-2 ESTeem Models 195MHC
without any handshaking. The second 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/H/C 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 ESTeems have 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/H/C 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. Each of these modes of operation are described in detail in Chapter 5.
Sensor Applications
The ESTeem 195C and 195M have four (4) 4/20mA sensor inputs. The sensor inputs can be read out of the 195M/H/C though
their ModbusTCP address, a software command or the Model 195M/H/C configuration utility. For complete details on the
configuration and operation of the sensor input, please refer to Appendix B – Interface Ports.
Legacy ‐ Model 192 Applications
The ESTeem 195C can be integrated with our legacy ESTeem Model 192C or Model 192CHP, while the 195M can be integrated
with Models 192M or 192MHP networks. The procedure for integrating the new 195C or 195M in an existing Model 192 network
can be found in Appendix C of this User’s Manual.
