The GE Microprocessor Board DS3800HMPK1H1H is designed for quick installation in the drive. The board features a modular connector on 1 end and retention levers on the other end. The GE Microprocessor Board DS3800HMPK1H1H also is populated with 3 red indicator LEDs and 1 amber LED which are visible from the front of the board. The board also is populated with a microprocessor, erasable programmable read-only memory (EPROM) modules, and a 34-pin connector. It also is populated with 2 50-pin connectors.
The GE Microprocessor Board DS3800HMPK1H1H is populated with EPROM modules and when the original board is shipped, the module sockets are populated with modules. The modules store the code used to control the microprocessor activity. The code is in the form of firmware and programming code. Without the modules the microprocessor are inactive. The microprocessor reads the firmware and programming code for processing instructions. The modules are never updated by the microprocessor. Instead, the microprocessor uses the same instructions without updates applied to it.
When you receive a replacement board, you will find that the module sockets are empty. The microprocessor on the board controls the operation of the board and to ensure the new board operates the same as the defective board it is best to use the same firmware and programming code. Be aware that the code on the modules is sensitive to static electricity. Wear a wrist strap when you handle a module. To remove a module, insert a screwdriver in the space between the module and the socket on the end of 1 socket. Lift up on the screwdriver to remove the module.
