產品描述
本光纖集線器用于組建星型光纖網絡, 實現12個單路RS232/485/422在光纖星型網絡上透明傳輸。自適應,無需改動用戶協議。由于采用了光纖作為傳輸介質,可以避免惡劣環境下雷電、浪涌、電磁干擾等對通信設備的威脅,同時省去了原來使用銅線時的雷電浪涌保護設備投資大大提高了數據通訊的可靠性、安全性和保密性。
功能特點
◆ 可與12個遠端單路RS232/422/485串口Modem組成星型網絡;
◆ 具備自動偵測串口信號波特率的能力;
◆ 可以自動檢測、控制RS-485數據流 不必要用握手信號來控制數據流向;
◆ 支持RS232/422/485接口,RS232波特率支持300-256KRS485/422波特率300-921K;
◆ 自動檢測每個光口的串口數據是否正常,自動屏蔽不正常的光接口(如所在的光纖modem串口打壞收到全0或線路短路),使其不影響整個網絡,并有指示燈指示;
◆ 串行口接口防雷達到IEC61000-4-5 (10/700μS) 差模:6KV 阻抗(2Ω);共模:6KV,阻抗(2Ω) 標準;
◆ 內置電源多種電源方式可選:AC220V、DC-48V/DC+24V/DC+V12等;支持AC+DC;AC+AC;DC+DC等雙電源模式;
