Overview:
E1 G.703 to RS232 converter realizes data conversion between ITU-T G.703 standard E1 and RS232interface. Date interface mode is DCE, could connect to DTE or DCE device.
Features:
RS232 rate support 0~115200Kbps self-adapt;
Support RS232 interface (TXD,RXD,GND)
RS232 support hot-plug, connection to DTE or TCE device;
offer 2 kinds of loop-return function, namely E1 self-looping at local end (ANA) and RS232 self-looping at local end (REM)
AC220V and DC-48V for option, and DC-48V is not divided into positive and negative pole with simple installation and maintenance;
has the function of pseudo-random code testing(PATT), which brings great convenience for installation, debugging and maintenance of equipment;
E1 interface supports 75ohm, unbalanced and 120ohm balanced impedance at the same time;
