DS200XDSAG1A is a Transducer Interface Terminal Board manufactured and designed by General Electric as part of the Mark V Series used in GE Speedtronic Gas Turbine Control Systems. The Transducer Interface (XDSA) terminal board is designed to be installed next to one or more Honeywell® Smart Pressure Transducers of type LG-1237 that support serial communications. Four cables with DB-25 connectors on either end that are compatible with Honeywell sensors are used to transmit serial data communications and deliver 12 V dc input power to the board. Two separate circuits are built into the board in a redundant sensor setup. To establish sensor addresses and choose the serial communications termination resistance, jumpers are available. Several XDSA boards can be connected together in a single system thanks to XDSA's characteristics.


Terminals 1, 2, 9, and 10 are supplied with 12 V dc 5% by two DPWA terminal boards. For RS-422 multidrop communications, use terminals 3 through 8 and 11 through 16. Two separate boards can be used on each XDSA terminal board. On each end of the board, one per sector, there is a stab-on-ground connection. Four pressure sensors are connected to the board using cables with DB25 connections on either end.


The board's bottom has the input terminal 1 and output connection P1. At terminals 1 (positive) and 2, an input power of 12 V dc 5% is applied (negative). A control sends out serial transmissions, with the transmission path termination set by jumper JP1, which are received on terminals 3 (positive) and 4 (negative). Terminals 5 (positive) and 6 are the locations for the serial output of connected pressure sensors (negative). According to the installation section, terminals 7 (positive) and 8 (negative) offer an additional XDSA board a pass-through path. The jumpers JP3 and JP4 control which device address is selected.


  • There are six jumpers available on the XDSA terminal board to choose the address of the pressure sensors as well as the termination resistors for RS-422 serial communication.
  • Serial input terminating resistor status is determined by jumpers JP1 and JP2. For the XDSA board that is at the end of the transmission path, in is chosen. Every other XDSA board in the signal path has been set to out.
  • The sensors linked to P1 through P4 have their addresses set by jumpers JP3 through JP6. Four signals are sent to the DB-25 connector, setting the sensor address. The signals are made up of jumper positions on the two least significant bits in addition to the fixed wire.
