据Spescom International公司报道:KY500型数据输入终端设备通过内部的Modem由HF/VHF/UHF无线、电话、双线路或采用中速跳频无线来传送保密字母数字信息。这种信息用键盘控制来选择Modcm,并以150 bps和600 bps的速度传输。该设备输入电压为7～30 Vdc(225mW),共有47个键。信息可以是任意的或一定格式的报文。纠错采用半速交叉编码,加密通过一个非线性密钥流产生器来实现,显示器为点矩阵LCD。若无另外说明,标准装置都配有ABC键盘。该装置有2500字符存储器(其内容在该设备断开时仍保留)、编辑设备、告警显示器及状态显示。工作温度范围为-10～+55℃,最大工作高度为5000米。选择部分包括用户选定格式,QWERTY和用户选定的键盘配置,用户选定的密码散布表及打印机。该装置体积为7.3125×4×1.75英寸,质量为1.875磅。
According to Spescom International, the KY500 Data Entry Terminal transmits confidential alphanumeric messages over HF / VHF / UHF wireless, telephone, dual line, or medium frequency hopping wireless over the internal Modem. This information is keyboard controlled to select Modcm and transmit at 150 bps and 600 bps. The device input voltage is 7 ~ 30 Vdc (225mW), a total of 47 keys. The message can be an arbitrary or a certain format of the message. Error correction using half-speed cross coding, encryption through a non-linear keystream generator to achieve, the display for the dot matrix LCD. Unless otherwise specified, standard devices are equipped with ABC keyboards. The unit has 2500 characters of memory (the contents remain when the device is disconnected), editing devices, alarm displays, and status displays. Operating temperature range of -10 ~ +55 ℃, the maximum working height of 5,000 meters. The selection section includes the user-selected format, the QWERTY and user-selected keyboard configuration, the user-selected password spreadsheet, and the printer. The device has a volume of 7.3125 x 4 x 1.75 inches and a mass of 1.875 pounds.
