The GE Digital I/O Board DS200TCDAH1B features one microprocessor and multiple programmable read only memory (PROM) modules. It also contains 1 block of 10 LEDs and 2 50-pin connectors. The GE Digital I/O Board DS200TCDAGH1B also is populated with 8 jumpers and 1 LED that is visible from the side of the board. The GE Digital I/O Board DS200TCDAH1B also features 2 3-pin connectors. One 3-pin connector has the ID JX1 and the other has the ID JX2.

The IDs assigned to the 8 jumpers are prefixed with JP. For example, one jumper is assigned the ID JP1. Another jumper is assigned the ID JP2, and so on. The test points also have a prefix assigned to the IDs. The prefix for the test points is TP. For example, one test point is assigned the ID TP1.

Another test point is assigned the ID TP2. With the use of a qualified testing device, a servicer can test the individual circuits on the board and pinpoint a fault that might be repairable.

The DS200TCDAH1BHD General Electric Digital I/O Board features one microprocessor and multiple programmable read-only memory (PROM) modules. It also contains 1 block made up of 10 LED lights and a pair of 50-pin connectors along with 8 jumpers and 1 green LED that is visible from the side of the board. The PROM modules are removable from the board and they reside in a socket embedded on the board.

When replacing the board or if you are in the process of replacing the PROM module for any reason, you can obtain a hand tool that is expressly designed for removing and installing the PROM modules. It is important to remember that the PROM module is easily corrupted or destroyed by static buildup. Protect yourself and the equipment by always wearing a wrist strap when you work on the board or any other board or component in the drive. When the wrist strap is connected to a metal desk or chair, the static is attracted to the grounded object and leaves your body and the board.

The GE Digital I/O Board DS200TCDAH1BHD features 8 jumpers, one LED on the side of the board, and 2 3-pin connectors. It also contains 1 block of 10 LEDs and 2 50-pin connectors. Each jumper on the GE Digital I/O Board DS200TCDAH1BJE has a ID. The prefix for each jumper ID is JP followed by a numerical value. For example, the ID for one jumper is JP1.

The ID for another jumper is JP8. Before you replace the board, identify each jumper and document which jumpers are covered. Then, examine the new board and set the jumpers on the replacement board to match the old board. For example, if JP1 has pins 1 and 2 covered on the old board, make sure that the replacement board has jumpers 1 and 2 covered also.

The jumpers are used to configure the board to meet the specific requirements of the site. Before the board is installed for the first time, the installer can refer to the information that shipped with the board to learn how the jumper positions define the operation of the board. The installer can change the positions of the jumpers to best suit the needs of the site. When the board ships from the factory the jumpers are in the default positions. This is the standard setting that typically meets the needs of the site.
