FUNCTIONAL DESCRIPTION:

DS200TBSAG1A is a Serial Communication Termination Module manufactured and designed by General Electric as part of the Mark V LM Series used in GE Speedtronic Control Systems. The TBSA terminal board is in location eight of . The pressure transducer signal wires from the externally mounted XDSA board for DLE applications and the FMVED serial link wires are connected to this terminal board. The pressure transducer signals are connected to the TCSA board in . The FMVED signals are connected to the PCM daughterboard on the IO Engine in .

TBSA CONNECTIONS:

• P3 - Receives 12 V dc power from TCSA in and connects it to DLE serial pressure transducers. This connection also links the pressure signals from the transducers back to the TCSA board in the core.
• P4 - Receives 12 V dc power from TCSA in and connects it to FMVED motor controllers.
• P5 - Connects FMVED communication channels 1 and 2 to P3 on the PCM daughterboard on the UCPB in .
• P6 - Connects FMVED communication channels 3 and 4 to P6 on the PCM daughterboard on the UCPB in

TBQB HARDWARE CONFIGURATION:

JP1 through JP16 - These hardware jumpers enable the transmit and receive communication circuits for the FMVED motor controller serial links.

TB1: The TB1 terminal board located in the core lands the incoming 115/230 V ac and 125 V dc power to the Mark V LM controller. ac power is connected to the TCPD board in the core and routed through the JZ2 and JZ3 connectors for ac to dc conversion in the DACA module(s). dc power is usually from a 125 V dc uninterruptable power source (UPS/battery) and is connected directly to TCPD through the TB1 terminal board. The JZ5 connector provides power for the ignition. The JZ4 connector is used for the same purpose, but with the auxiliary ac signals. TBSA - Terminal Board with screw terminations for the DLE gas pressure sensor serial link and Fuel Metering Valve Electric Drive (FMVED) serial link. Location 8 in .

TB2: The TB2 terminal board allows the excitation voltage for contact inputs (DTBA and DTBB terminal boards in the digital cores) to be 125 V dc from core or 24 V dc from

core. Implementation of the desired contact input excitation option is done at the factory.

1TB: The 1TB terminal board is located in the core and receives Genius Global Data signals. It is connected to the GEN1 and GEN2 connections on the UCIB board in the core.

FREQUENTLY ASKED QUESTIONS:

What is a Serial Communication Termination Module?

A Serial Communication Termination Module is a device or circuit used to properly terminate serial communication lines, such as RS-232 or RS-485, to prevent signal reflections and ensure reliable data transmission.

Why is termination necessary in serial communication?

Termination is necessary to prevent signal reflections caused by impedance mismatches along the communication line. These reflections can distort signals and lead to data errors or corruption.

How does a Serial Communication Termination Module work?

The termination module provides the correct impedance matching at the end of the communication line, effectively absorbing any signal reflections and ensuring that the signal is properly transmitted without distortion.
