About the DS3800HIOA
The GE Input Isolator Board DS3800HIOA features a hole in each corner for installing the board with screws in the drive interior. The GE Input Isolator Board DS3800HIOA also is populated with a microprocessor and multiple erasable programmable read-only (EPROM) modules. The board has 1 34-pin connector that is accessible from the front of the board. It also is populated with test points and 1 40-pin connector on the surface of the board.
The erasable programmable read-only (EPROM) modules snap into a socket that is embedded on the board. They can be removed from the socket if the board is replaced in the drive. They can also be removed if the firmware and code is updated with an updated version. Often code is not updated because once the board is installed and it successfully receives commands signals and processes the signals, the site continues to use the same version of the programming code and firmware. However, the modules are removed if the board is replaced. The board might be replaced if it is defective.
The replacement board is shipped you without EPROM modules installed and so the servicer must remove the modules from the defective board and install them on the new board. Locate 1 short end of the module socket and insert a screwdriver between the socket and the module. Twist the screwdriver and loosen 1 end of the module. Repeat the action on the other short end of the socket and place the module in a static protective bag.
