408地震仪FDU标识号存储器与置号机

FDU ID memory and ID write-in device in 408 seismograph.

408遥测地震仪维修站TMS 408没有采集站(FDU)标识号写入功能。存放FDU标识号的存储器损坏或者其中存放的数据紊乱后,FDU就不能进行数据采集。本文介绍408地震仪FDU标识号存储器及一款利用个人计算机双向并行打印口读写FDU EEPROM芯片的装置。

There is not ID write function for FDU in TMS408. The FDU can＇t implement data acquisition when the FDU ID memory damages or confusion of stored data. The paper introduced FDU ID memory of 408 seismograph and a device using a bi-directional parallel port for printer on a personal computer to read/write FDU F.EPROM chip.
