Description
AN-E1-4(8)RS485 is E1 G.703 to RS485 converter that realizes data conversion between ITU-T G.703 standard E1 G.703 and 4 or 8 RS485 interface. Date interface mode is DCE, could connect to DTE or DCE device, RS485 can transmit asynchronous 0~115200Kbps self-adapting speed.
Features
-
AN-E1-4(8)RS-485 can realize long-distance monitoring of this end equipment to the far-end equipment (two-row indicator, upper row indicate local status, lower row indicate far-end status);
-
RS485 rate support 0~115200Kbps self-adapt
-
RS485 support hot-plug, connection to DTE or DCE device;
-
4 or 8 RS-485 interfaces over E1 G.703/G.704
-
Rate selection for each RS-485
-
E1 can support rate N*64k (N=1 to 32)
-
Offers 2 kinds of loop-return function, namely E1 self-looping at local end (ANA) and RS485 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;
-
Supports function of pseudo-random code testing(PATT), which brings great convenience for installation, debugging and maintenance of equipment;
-
E1 interface supports 75Ω unbalanced and 120Ω balanced impedance at the same time;
-
Realizes SNMP network management function in our chassis installation
