GETC Logic Board connector J19.
10. Connect the Regulator Board harness assembly
(A2W1) plug P1 to the GETC Logic Board
connector J27.
Jumper Installation
There are a few jumpers on the GETC Logic Board
which must be re-configured for CNI operation. To
properly configure the jumpers, refer to Table 2 and install
or remove jumpers according to table. The location of the
jumpers may be found using the board layout diagram in
Figure 7 or by referring to the full scale GETC Diagrams in
LBI-38988.
GETC FIRMWARE INSTALLATION
The firmware installation procedure involves installing
the latest version of the CNI EPROM (344A3497) into the
CNI GETC.
EPROM Installation
Perform the following steps to install the CNI GETC
firmware:
1. Remove power from the GETC and place the
GETC shelf in the service position. This will
allow access to the EPROM.
2. Remove the GETC EPROM U2.
3. Install the CNI EPROM into the XU2 socket
(ensure the EPROM’s pin 1 is properly aligned
with pin 1 on the socket, see Figure 4).
4. Proceed to the Software Installation procedure.
TURBO SOFTWARE INSTALLATION
The two Turbo Board processors communicate with
each other through a parallel bus. Communication with the
main GETC processor is through the 8K dual port RAM
bank comprised of U3 and U4. In addition, each turbo
processor has an RS-232 serial port used for Turbo
Programming.
CNI stations built in the factory come with the latest
software. To upgrade an existing station, refer to the
software release notes for the appropriate version of the
Turbo Board software. It will vary with the version of
GETC Logic Board software. Group 1 of the CNI software,
344A3497G1, is compatible with Group 1 of the Turbo
Board software, 344A4414G1.
