The GE I/O TC2000 Analog Board DS200TCCAG1BAA features one 80196 microprocessor and multiple programmable read only memory (PROM) modules. It also contains one LED and 2 50-pin connectors. The LED is visible from the side view of the board. The IDs for the 50-pin connectors are JCC and JDD. The PROM modules on the GE I/O TC2000 Analog Board DS200TCCAG1BAA store instructions and firmware used by the microprocessor and programmable logic device. The information is embedded on the PROMs and can erased and a newer version stored on the PROMs.
The PROM modules are removable from the sockets that are integrated on the board. To remove a PROM module, insert a flat-bladed screwdriver under one end of the module and gently lift up the screwdriver and the module will pop up. Then, insert the screwdriver on the other end of the module and perform the same action. Immediately place the module in a static protective bag.
To install a PROM module, align the module with the socket and avoid touching the pins on the module. Press down on the module to install it. Always wear an EDS protective device, like a wrist strap because the modules are sensitive to static. The information on them can be corrupted or destroyed.
To ensure the replacement board processes the same as the formerly used board, remove the modules from the old board and install them on the new board. In this way, the instructions and firmware code will be the same.
