人们在选购扫描仪时，除了关心扫描仪的分辨率、色彩深度、扫描幅面等重要指标以外，最需要关心的就是扫描仪接口了。
扫描仪常用的接口有三种： SCSI 、EPP 和 USB。
由于不清楚这几种接口各自的特点，用户在选购扫描仪时往往无法确定哪种扫描仪更适合自己。
为了方便用户选购合适的扫描仪，下面简要介绍一下这三种接口各自的特点和适用范围。
SCSI 、 EPP 和USB种接口中， SCSI可以说是元老了。
SCSI是小型计算机系统接口的缩写，起初是为了在微型机上连接多台高速外设而发明的。
SCSI接口的主要特点传输速度高:现在最快的SCSI接口的传输速度已经达到160MbpS，在常用的接口中是最高的，而且由于SCSI接口自带一块微处理器，可以帮助计算机完成许多工作，从而大大降低了CPU的负担，使计算机的总体性能比较高。
这也是为什么高级服务器必须使用SCSI接口的原因，可连接的设备比较多一个SCSI接口可以同时连接7到15个设备，不仅可以连接硬盘、光驱、磁带机等存储设备，还可连接扫描仪等输入输出设备。
所以当计算机的设备比较多时（例如服务器或工作站），使用SCSI接口是明智的选择。
价格昂贵、安装不方便:SCSI 接口需要一块独立的控制卡，而SCSI控制卡的价格一般比较昂贵。
普通个人计算机通常不配备SCSI 控制卡，所以如果要使用SCSI接口的扫描仪，必须先在计算机中安装一块SCSI 控制卡，这对于普通用户来说是很不方便的。
使用SCSI接口的扫描仪的主要特点就是速度快、价格昂贵，比较适合于出版、印刷、美术等专业领域使用。
使用SCSI接口的扫猫仪有紫光Uniscan 4C+系列、敦煌D2000等。
EPP 接口是从原来的普通打印口发展而来的，叫做增强型并行接口。
现在的个人电脑一般都配备了EPP接口（就是并行口）。
EPP 接口有以下几个特点：速度较慢：EPP接口的传输速率一般只能达到IMB左右，比SCSI 接口慢很多。
应用范围小：EPP接口一般只能连接打印机、扫描仪等少数几种设备。

MS210扫描器操作说明第一章：概述第二章：键盘接口第三章：RS232接口第四章：终端接口第五章：光笔仿真接口第六章：设置Display VersionFactory Default第一章概述感谢您使用Unitech的产品。
扫描器的最主要的功能是可以取代键盘的输入，从而提高输入速度及准确性。
Unitech的任何一款扫描枪都可支持键盘口、USB口、RS232、光笔仿真模式。
应用时，选择不同类型的接口方式时，需选择相应的连接线及对扫描器进行相应的接口方式设置。
如果您是通过键盘口安装，扫描器支持绝大部分的主流PC及IBM终端。
键盘口的安装相当简单，且不需对相关软件和硬件进行修改。
如果您是通过RS232串口安装，则扫描器通过RS232协议发送数据，通讯的速度（波特率）可以从300bps 到38400bps进行选择，硬件及软件握手需遵循协议规定。
扫描器支持下列的条码类型：Code 39standard and Full ASCⅡ；Codabar;UPC/EAN with supplement codes; UCC/EAN 128;Interleaved 2 of 5; Code 32(Italian pharmacy);Standard 2 of 5; Code 93;MSI code; Code 128;Plessey code; Label code Ⅳand Ⅴ；China postal code (Toshiba code);第二章键盘口所谓的键盘口安装，是将扫描器连接在PC（或终端）与键盘之间（见Figure 1）。
通过键盘口将数据送到主机上，是键盘的一种延伸。
一、 安装通过下图，您可以轻松地将扫描器安装好。
首先从盒子内将“Y”型连接线取出。
安装步骤：1．确认扫描器具有正确连接系统的Y（L）的键盘接线，将RJ45插入到扫描器底部的接口；2．关掉系统电源；3．将键盘剥离系统；4．将Y（L）接头的两个接口分别接到键盘的系统，以串联的形式连接，可同时接多台；5．打开系统电源；6．如果无法连接，请您检查所有的连线是否正确。
