PURPOSE
The converter enables access to the RS-485 serial port from any computer in the local network, and when the IP is shared
on the Internet also from any computer in the world connected to the Internet. It also acts as a serial port server. The
communication is carried out via TCP, UDP, DHCP, and other protocols.
The available software allows you to create a virtual serial port on your PC and access the serial interface of the ATC-1000
converter attached anywhere on the network just like the local COM port of that PC. This converter has a wide range of
power supply options: 9-24 VDC.
OPERATING MODES
Server
Client
Server:
a. LAN Local Area Network
The MeternetPRO server initiates a connection to the converter with a static IP address.
b. Remote communication over the Internet

The MeternetPRO server initiates a connection to the converter to a public IP address for a location with the converter.
Forwarding the request on the router to the designated communication port of the converter.
Client:
a. LAN Local Area Network
The converter initiates a connection to the MeternetPRO server with a static IP address.
b. Remote communication over the Internet
The converter initiates a connection to the MeternetPRO server to a public IP address for a location with the server.
Forwarding the request on the router to the designated communication port of the MeternetPRO server.

TCP mode –TCP protocol settings
Telnet Server - network connection mode. Select the appropriate communication option: SERVER or CLIENT.
Port Number - converter network port number. Set an individual number in the given network.
Remote Server IP… - for CLIENT operating mode: IP address of the master device with which the converter
establishes communication.
Client mode... - for the Client operating mode: setting the timeout interval [sec] for waiting for data, after
which the connection to the Server device will be closed and a new connection to the Server
device will be established. Set the timeout approximately 1.5 times greater than the query
interval of the Slave devices by the MeternetPRO system, for example query interval = 60 sec x
1.5; timeout = 90sec.
Server mode... - for the Server operating mode: setting the timeout interval [min] for waiting for data, after
which the connection to the Client device will be closed and the waiting for a new request from
the Client device will start. Set the timeout approximately 1.5 times greater than the query
interval of the Slave devices by the MeternetPRO system, for example query interval = 60 sec x
1.5; timeout = 90sec.
Update - confirmation of the changes made to the configuration
