2.2. DESCRIPTION
ADA-13020 converter is used for data transmission between devices equipped with Current Loop interface via LAN/WAN network
without interfering with data format. In the ETHERNET network converter can operate in Virtual Serial Port mode, TCP serial bridge
mode, UDP serial bridge mode, TCP sockets, UDP sockets. The converter has screw terminal block for connection of Current Loop
interface and power supply and RJ45 connector for Ethernet network connecting. Converter uses for operating signals
RX+,RX-,TX+,TX- of Current Loop interface, connected via screw terminal block.
Over-voltage protection was made on base safety diodes and fuses on each Current Loop lines.
To Current Loop interface can be connected one device in point-to-point topology, operates in half duplex or full duplex mode.
This converter has internal, low energy surge protection for each Current Loop lines however it is recommended to use the external
lightning arresters (typical protection of telephone line) for the lightning protection of lines
With converter are provided the drivers which installed in the operating system (Windows 98ME,2000,XP,2003,Vista,7, 8, 8.1, 10), 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.
Version with active trans/- 20mA
