IS200DSPXH2D - DSP Control Board

SPECIFICATIONS

Part No.: IS200DSPXH2D
Manufacturer: General Electric
Function: Digital Signal Processor Control Board
Availability: In Stock
Series: EX2100
Product Type: PCB
Country of Manufacture: United States (USA)

Functional Description

IS200DSPXH2D is a DSP Control Board developed by GE. It is comprised of a high-performance digital signal processor (DSP), standard memory components, and an application-specific integrated circuit (ASIC) that performs custom logic functions. A CompactPCI® (CPCI) enclosure houses the controller. A 6U high rack, one or two 3U high power supplies, a 6U high single board, and a cooling fan are typical components of a CPCI enclosure.

Features

• The previous board had an ISBus revision as well, but the ISBus revision on is a second version, indicating that it should replace the DSPXH1B model.
• This board provides the same basic functions as the previous two models, such as processing, logic, and interface functions.
• The load pulse signals on the board serve as an inner loop load pulse signal, capturing the values of the inputs and outputs, as well as an application loop load pulse signal, capturing other applications.
• The LED DS1 functions as a fault nomenclature and is red when lit; the LED DS2 functions as a status nomenclature and is green when lit. If the DS2 LED is on but not flashing, the board has stopped; if the LED is flashing, the board is running; and if the LED is not lit, a fault has most likely occurred.

Specialized Hardware Functions

Custom logic in Field Programmable Gate Arrays (FPGA) or ASICs with supporting circuits is used to provide specialized functions on the DSPX board. ASICs contain the majority of specialized and support functions. P1 has four serial interfaces, which are as follows:

• Two 5 Mb/s ISBusTM interfaces that can be used as master or slave
• One asynchronous TTL interface for a computer-based configuration tool, with RX, TX, and TXEN/RTS data signals
• One asynchronous TTL interface to a programmer board, including data signals RX, TX, and RTS

Board Replacement Procedure

1. Check that the exciter has been turned off.
2. Open the control cabinet door and make sure the power indicators on the EPDM (if present) and EPSM power supplies, as well as the DSPX LEDs, are turned off.
3. Disconnect the EISB front panel's six fiber-optic cables.
4. Carefully remove the DSPX board and its attached EISB board from the control rack, as shown below:
   
   1. Loosen the screws near the ejector tabs at the top of the DSPX faceplate and the bottom of the EISB faceplate. (The screws in the faceplate are captive and should not be removed.)
   2. Remove the DSPX and EISB by pulling up on the ejector tabs.
   3. Gently pull both boards from the rack with both hands.
5. Remove the EISB from the DSPX's bottom and connect it to the replacement DSPX.
6. Insert the replacement DSPX and EISB boards into the appropriate rack slot.
7. Begin seating the board by firmly pressing the top and bottom faceplates with your thumbs at the same time.
8. Finish seating the module in the slot by tightening the screws at the top and bottom of the faceplate assembly alternately. To ensure that the module is seated squarely, tighten the screws evenly.
9. Reconnect all communication cables that were removed with the old module.

Frequently Asked Questions

What is IS200DSPXH2D?
It is a DSP Control Board developed by GE

What is the ISBus revision of the board?
The board has a second version of the ISBus revision.

What is the function of the load pulse signals on the board?
The load pulse signals on the board serve as an inner loop load pulse signal, capturing the values of the inputs and outputs, as well as an application loop load pulse signal, capturing other applications.

What do the LED DS1 and DS2 on the board indicate?
The LED DS1 functions as a fault nomenclature and is red when lit; the LED DS2 functions as a status nomenclature and is green when lit. If the DS2 LED is on but not flashing, the board has stopped; if the LED is flashing, the board is running; and if the LED is not lit, a fault has most likely occurred.
