Specifications

This procedure provides instructions for programming
the Turbo Board installed in the CNI GETC. The
installation process uses the software diskette 344A4414, an
IBM compatible personal computer (PC), and an
interconnecting cable (TQ-3360).
The PC reads data from the files on the 344A4414
diskette and transfers the data to the Turbo Board
microprocessor through connectors J103 and J104 at the
rear of the GETC Shelf.
Running the "load1e.exe" executable program serially
moves data from the "1etop.hex" and "1ebot.hex" files to
the code segment of the Turbo Board’s memory.
The "1ecrc.hex" file provides Cyclical Redundancy
Check (CRC) information for use in error checking and
verification during the file transfer or "programming"
process. Any errors encountered during this procedure
generally indicate a defective communication link between
the PC and Turbo Board.
Preparation
Prepare the PC for programming the CNI GETC Turbo
Board by performing the following steps:
1. Connect the TQ-3360 programming cable from the
PC’s serial port connector to the GETC Shelf
connector J104 (see Figure 8). (A DB-25 to DB-9
adapter may be needed.)
2. Using standard DOS commands or a software file
manager, create a directory named "LOAD1E" on
the PC’s hard drive.
3. Make "LOAD1E" the current default directory and
copy the following files from the software diskette
into the "LOAD1E" directory:
• load1e.exe
• 1etop.hex
• 1ecrc.hex
• 1ebot.hex
4. Move the Turbo Board run/load switches S2 and
S3 to the load position (toward the front of the
GETC shelf). The front position of S2 and S3
places the processors U1 and U2 into the
programming mode. If either switch is already
toward the front, move the switch to the rear and
then back to the front position.
5. The Turbo Board LEDs D1 and D2 should turn
OFF indicating that the Turbo Board is in the
programming mode.
Programming Mode
This procedure downloads the Turbo Board software to
the microprocessors U1 and U2 on the Turbo board.
1. Execute the "load1e.exe" program on the PC and
follow the on screen instructions.
The "load1e.exe" program loads the file
"1etop.hex" into the Turbo Board’s upper half of
memory for use by the top processor U1.
2. Monitor the PC’s on screen instructions and
prompts.
3. When directed, move the TQ-3360 programming
cable from the GETC Shelf J104 to J103.
4. The PC will indicate it is loading the "1ebot.hex"
file into the Turbo Board’s lower half of memory
for use by the bottom processor U2.
Normal Mode
Upon successful completion of the programming mode,
the PC displays a "FINISHED" message. It will also
provide instructions to switch S2 and S3 to the rear position
for normal operation.
If an error occurs, check connectors and cables. Cycle
S2 and S3 from the front position, to the rear position,
and again to the front position. If the PC continues to
indicate an error, refer to the Turbo Board
Maintenance Manual LBI-38822.
NOTE
Re-programming the GETC Turbo Board will not alter
previously stored Personality Data. When Personality
Data is present, "load1e.exe" clears and performs CRC
functions over the code portion of memory only.
