The ADA-13021 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 ADA-13021 converter transmits data via Current Loop interface with the baud rate 38,4kbps by the use of 2-pair of twisted-pair cable. The converter has screw terminal block for connection of Current Loop interface and power supply and RJ45 connector for Ethernet network connecting. ADA-13021 uses for operating the signals: RX+,RX-,TX+,TX- of Current Loop interface.
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.
