产品中心 >> SATELLAR智能型数传电台 >> SATELLAR
SATELLAR产品是新一代的数字式数传电台系统，它由几个不同的单元组成： • 中心单元 (CU) • 通信单元 (RU) • 扩充单元 (XU) SATELLAR产品使建立独立的，可靠的，实时的无线数据通信系统能够符合客户的特殊需要。比较典型的例子是一个中心单元连同一个通信单元一起在一个网络中作为一个主站或在一个需要以太网连接的场所中使用。如果是用在通信路由站，中心单元不是必需的。因为产品的模块化结构，在这些例子中，通信单元可以单独使用。 SATELLAR 单元既可以作单独的个体又可以作组合的产品包： • SATELLAR-2DS 包括一个通信单元和一个中心单元，确保了TCP/IP协议完整的连通性。 • SATELLAR-2DSd提供了与SATELLAR-2DS 同样的功能, 但是它被安装了一个彩色显示屏和一个按键区。 • SATELLAR-1DS 是一个通信单元，可以用在一个有足够标准RS连接的位置。
