2.4.5 Cable Jumper Settings
On the PCBs that use them, the jumpers on the cables are used for board addressing. The jumper
settings are automatically determined by the compiler when the application program is written.
This information is clearly defined and available to the user in the list file (.GNL), which is one
product of compiling an application text file (.GN2). If this file is unavailable, the user can
determine the jumper settings by following the instructions below. By far the best way to
determine the jumper settings is to use the list file.
The jumper settings for each board are determined by the order in which the boards are defined
in the user-written application program. The jumper settings
do not
depend on the order the
boards happen to appear in the cardfile. If the application program and list file are both
unavailable, then the order can also be found by looking at the configuration menu in the
GENISYS II Maintenance Tool. (See Section 6.2 in the 6900C manual.) The buttons for the
board listing in the configuration window are in the same order, from left to right, as they are in
the application.
