2.2. DESCRIPTION
The
ADA-13040MG
converter is used for data transmission between devices equipped with RS485/ RS422 interface via LAN/WAN
network. In the ETHERNET network converter can operate in Virtual Serial Port mode, TCP serial bridge mode, UDP serial bridge
mode, TCP sockets, UDP sockets and MODBUS Data Gateway . The MODBUS Data Gateway converts MODBUS-RTU master/slave
and MODBUS-ASCII master/slave protocol to MODBUS-TCP and inversely. This allows for integrate MODBUS-RTU/ASCII with
MODBUS-TCP devices within one network.
Converter uses protocols: TCP, UDP, DHCP, SNMP, SSL/TLS, Telnet, Rlogin, LPD, HTTP/HTTPS, SMTP, ICMP, IGMP, ARP. It has a
built-in WWW web server what allow you to configure and menage it via internet browser. The ADA-13040MG supports the baud rate
230,4 kbps via RS485/RS422 interface and use RX+,RX-,TX+(A),TX-(B) signals. It is possible to connect 32 devices operating in half
duplex mode to RS485 network constructed on the ADA-13040MG.
The Converter is adapted to supply an external voltage source fron 10V to 30V and power 3W. ADA-13040MG has implemented
protection against opposite polarization of power supply and over-voltage protection on RS485/RS422 network. Converter has
galvanic isolation between ETHERNET and RS485/RS422 interface and power supply and optoisolation in signal channel between
ETHERNET and RS485/RS422 interface.
We provide with converter the drivers which installed in the operating system (Windows 98ME,2000,XP,2003,Vista,7), will create an
additional COM port. This port is the next free number eg COM3, can be used like a standard COM port. However it is not the real port
existing in a computer, but only a virtual, created by the system, therefore some programs running under DOS and links to this COM
port may not function properly.

2.3. ETHERNET NETWORK COMMUNICATION
2.3.1. TCP/UDP SOCKED MODE COMMUNICATION
Communication in the mode TCP/UDP sockets allows an application (SCADA, MMI) to transfer data to the serial port of ADA-
13040MG via Ethernet network by the use of client and server TCP/UDP services.
2.3.2. COMMUNICATIONS IN THE VIRTUAL SERIAL PORT MODE (RealPort)
Communication in the virtual serial port mode allows an application (SCADA, MMI) to transfer data to the serial port of ADA-13040MG
via Ethernet network, by the use virtual COM port , created in an operating system.
