DS200TCCBG8BED 80196微处理器和多个PROM模块

GE I/O TC2000模拟板DS200TCCBG8BED具有一个80196微处理器和多个PROM模块。它还包含一个LED和2个50针连接器。从单板侧面可以看到LED。50针连接器的id为JCC和JDD。微处理器是一个16位的微处理器，用于管理单板的操作。PROM模块安装在板上的插座中，使服务人员能够使用手动工具拆卸模块或安装模块。PROM模块包含固件和控制微处理器的编程指令。这些模块是可擦除的，这意味着可以对它们进行更新。这些更新可以从网站下载并应用到模块中。待更换的模块未安装PROM模块。这使得安装人员可以轻松地将PROM模块从旧板移动到替换板。通过这种方式，固件是相同的，这确保了微处理器在驱动器重新启动时的行为相同。

静电会损坏PROM模块，在操作时应遵循防静电操作准则。也就是说，内存可以被静态破坏或擦除。为防止损坏，在安装单板的过程中，请始终佩戴好腕带。腕带的一端系在安装人员的手臂或手腕上。另一端夹在没有油漆或其他覆盖物的金属表面上。

The GE I/O TC2000 Analog Board DS200TCCBG8BED features one 80196 microprocessor and multiple PROM modules. It also contains one LED and 2 50-pin connectors. The LED is visible from the side view of the board. The IDs for the 50-pin connectors are JCC and JDD. The microprocessor is a 16-bit microprocessor and is used to manage the operations of the board. The PROM modules are installed in sockets on the board which enable the servicer to remove the modules or install them with use of a hand tool. The PROM modules contain firmware and programming instructions that control the microprocessor. The modules are erasable which means that updates can be applied to them. The updates can be downloaded from a web site and applied to the module. The replacement module comes without PROM modules installed. This allows the installer to easily move the PROM modules from the old board to the replacement. In that way, the firmware is the same which ensures that the microprocessor will behave the same when the drive is restarted.

Proper guidelines for ESD must be followed due to the fact that the PROM modules are damaged by static. That is, the memory can be corrupted or erased by static. To prevent that, wear a wrist strap at all times when you install the replacement board. One end of the wrist strap is attached to the arm or wrist of the installer. The other end is clipped to a metal surface that is clear of paint or other coverings.
