The DS200TCQBG1BBA GE RST Extended Analog I/O Board is populated with a programmable logic device and EPROM modules along with 1 OK LED that is viewable from the side, 1 50-pin connector and 15 jumpers. The LED enables the operator to check the status of the board at a glance. When lit, it means the board is receiving power and is functioning.

The operator can view the operations of the board from the board cabinet on the drive along with the operations of other boards in the cabinet. This is a large board that is covered with two relays located side-by-side on the right side of the board near two heat sinks. Over a dozen jumper switches are used to customize board settings and there are multiple connectors, including three vertical pin cable connectors and a header connector. The board is also populated with multiple test points that are valuable for testing the specific circuits on the board. Each test point has an ID that is prefixed with TP and suffixed with a number. For example, the ID for one test point is TP1 and for another the ID is TP12. In order to use a test point the operator must have a testing device that is designed for performing the specific test on the circuit board and that device must be fully calibrated. In addition, the settings on the front of the testing device must be appropriate for the testing.

The GE RST Extended Analog I/O Board DS200TCQBG1B is populated with a  programmable logic device and EPROM modules. It also has 1 OK LED that is viewable from the side, 1 50-pin connector, and 15 jumpers. When you obtain a replacement GE RST Extended Analog I/O Board DS200TCQBG1B it ships to you without erasable programmable read-only memory (EPROM) modules. The EPROM modules store the firmware and programming the logic device uses to process information. However, the EPROM modules can easily be removed from the old board and installed on the new board. Use a flat-blade screwdriver to pry the module off the socket. Use care to avoid hitting or scratching other components on the board while you remove the modules. Store the modules in a safe place until you need them.

Wear a wrist strap whenever you work on the board or handle the modules. The modules are sensitive to static and the information on them can be damaged. After you remove the modules put them in a static protective bag. As added protection, touch the bag to the exterior of the drive before you take out the modules. This enables the static to seek out the grounded metal surface of the drive and exit your person and the modules.
