Product Description

Digital Signal Controller Board model IS200DSPXH1B is one of the DSPX models that can be used in conjunction with the EX2100 Excitation Controller series. The DSPX model is not equipped with any fuses, does not have any adjustable hardware, and does not contain any user test points. If your IS200DSPXH1B model is being used in conjunction with the EX2100 Series the DSPX board will be attached to another board which is known as the EISB; if needed these two boards can be detached. 

Four different memory types are available within your IS200DSPXH1B model, they are NVRAM, RAM, add-only memory, and FLASH memory. Each memory has an original function, the functions are as follows; the RAM is typically used for the execution of codes and storage of data; the NVRAM is used for the nonvolatile storage of data; the add-only memory of your DSPX board allows for identification of revisions, and the FLASH memory of the board is used for the execution of code, history records within the system, and memory for digital signal processor boot images. 

The IS200DSPXH1B model is a microprocessor-based control that is used to execute the exciter controller's code. This model is also one of the main controllers that shares responsibility with an application control layer module (ACLA) board. 

Frequently Asked Questions about IS200DSPXH1B

Is there a difference between the previous DSPX board and the IS200DSPXH1B board?

Yes, the main difference between the IS200DSPXH1B board and the previous version of the board is that this board has a functional revision. The functional revision of this board is an ISBus revision. 

The IS200DSPXH1B board must have I/O Definitions, what are these definitions and their basic functions?

The I/O Definitions provided with the IS200DSPXH1B board are a P6 engineering monitor port that connects to the DSP synchronous serial port, a P1 backplane connector that provides memory mapping, and a P5 DSP emulator port that provides a scan interface to allow for emulation as well as FLASH programming. 

Where is the IS200DSPXH1B model mounted and are there any explicit connections that must be made?

The IS200DSPXH1B board is mounted in the board rack and will connect to the backplane through a 128-pin, 4-row DIN connector. The DSPX model is attached to another board within the EX2100 series, said model being the EISB but the two boards can be detached. 

If I need to replace the IS200DSPXH1B board how can I do so?

You can replace the IS200DSPXH1B board offline, to do so ensure that the exciter has been de-energized. Once the exciter has been de-energized check all of the LEDs within the control cabinet to make sure that they are all powered off, you can disconnect the six fiber-optic cables from the EISB front panel once it is confirmed all LEDs are off. You will have to remove both the DSPX and EISB boards to replace the IS200DSPXH1B board. When the board has been removed from the cabinet and EISB board you can attach the replacement board to the EISB board and then slide the replacement back into the correct slot and firmly press the top and bottom of the faceplates. Reconnect all communication cables that were disconnected when the old module was removed. 

Reviews For IS200DSPXH1B

Internal Review

The IS200DSPXH1B module does not come equipped with user test points, due to the lack of these test points it makes it difficult for any tests to be run on this digital signal processor board. - AX Control Tech Team
