The GE Microprocessor Board DS3800DMPC1F1E features 1 programmable timer module (TPM). The GE Microprocessor Board DS3800DMPC1E1C also is populated with 1 34-pin ribbon cable, 1 50-pin ribbon cable, and 3 jumpers.
The jumpers on the GE Microprocessor Board DS3800DMPC1E1C have IDs that are prefixed with the letter J which is followed by a number. The IDs are J1, J2, and J3. The IDs are printed on the board and are adjacent to the jumpers. Use the jumpers to configure the board. The written instructions for installing the board include a description of the jumpers and what segment of the processing they configure. Each jumper has 2 positions you can choose from. One position is installing the jumper over pins 1 and 2. The other position is installing the jumper over pins 2 and 3. The jumper is a small plastic part that fits over the 2 pins and connects the 2 pins. A signal passes between the 2 pins that forces the board to process information in the configuration you selected.
The 34-pin and 50-pin ribbon cables are attached to the board and are not designed to be removed from the board. The 34-pin ribbon cable terminates in a 34-pin connector. The 50-pin ribbon cable terminates in a 50-pin connector. They are both 5-inches in length. They are designed to attach to connectors that are adjacent to the board when it is installed in the rack. Press the connector on the cable into the connector in the drive and make sure it is fully connected.
