Chapter 1. Product Overview
Purpose
EDM106 – a series of bidirectional interface converters
for connecting the devices with RS 232/RS 485/RS-422
interfaces to Ethernet networks. Data received on the
Ethernet port over a TCP channel are transmitted to the
serial ports. Data received on the serial ports are
transmitted in TCP packets over Ethernet.
Converters are designed for data transmission in
systems for automation, dispatching and resource
accounting. The presence of independent interfaces RS-
232, RS-485 and RS-422 allows to use the converter to
connect a wide range of devices: meters, controllers,
sensors, actuators, PLCs, etc.
The series includes the following models:
EDM106 – converter with non-isolated RS-485 interfaces.
EDM106-G – converter with galvanically isolated interface RS-485 (package includes the
terminating resistor 120 Ohms and PVC tubing (Cambrick)).
Converter's features
•
Independent interfaces RS-232, RS-485/RS-422 for connecting industrial devices. Connection of
up to 256 devices via RS 485/RS-422 interfaces.
•
8.5V output for power supply of external devices.
•
32-bit microcontroller, processing the network traffic efficiently.
•
Operating modes TCP server and TCP client.
•
Built-in DHCP-client and DNS-client.
•
Watchdog reboot timer that protects the device from freezes and failures.
•
Configuration of the converter through a simple and user-friendly web interface, as well as
through the console.
•
Extended LED indication of: power supply, connectivity and activity of each port.
•
The compact metal housing, allowing to install the converter into the telecommunication and
electrical cabinets.
•
Supply voltage range: 10–30V DC.
•
Wide operating temperature range: -40…+70
C.
Scope of application
EDM106 converters are widely used in automated systems for monitoring and control of technological
objects and processes, allowing to poll the meters, to manage the loads, to perform remote
configuration and administration of industrial devices remotely.
