Extron P/2 DA1是一款尺寸极其紧凑的1路输入1 路缓冲输出VGA-UXGA 线路驱动器。它在使用ExtronVGA MHR 电缆等高质量电缆时能将高清晰度计算机视频信号驱动远至80 米。P/2 DA1能对信号进行放大和清晰度控制，使视频信号能够远距离传输，重现更亮、更清晰的图象；这对输出视频信号功率很低的膝上型计算机来说很有用。P/2 DA1 线路驱动器还将许多膝上型计算机中常见的低电平同步电压（低至2V ）恢复到正常的TTL电平。这使得膝上型计算机能兼容更多的显示设备和电缆类型。显示器的识别位被传递到膝上型计算机中。P/2 DA1 线路驱动器装在一个如适配器大小的机壳内，能够直接连接膝上型计算机。
特性
·兼容VGA-UXGA图形卡、监视器、投影机、以及带15针HD 输出的Mac计算机
·300MHz （-3dB ）的RGB视频带宽
·缓冲输出
·用户可选的增益/图象清晰度调节
·塑料机壳
·P/2 DA1 （通用型）使用100-240V交流的桌面国际通用电源（自带）
·P/2 DA1 USB 带有一根USB电源线，通过膝上型计算机的USB端口供电
·计算机的技术参数，以确保USB端口供电正常。
·注：P/2 DA1 USB需使用达100mA 的电流，用户应查看其
