To avoid potential conflicts that may arise if commands are issued by multiple sources, the
EDSU should monitor any commands allowed to pass-through to the lens to verify commands
meet lens specifications and do not cause conflict with current EDSU operation.
. If the EDSU is not logging data but only generating OD data, then Commands D, C, Kd, Kc
can be allowed without conflict. In general, control of film size and data append functions
should come from a single source to avoid conflicts. Similarly, changes to Baud rate or checksum
mode have “difficult to follow” implication and it may be simpler to block all such commands.
To block a command, the EDSU should respond to the command from the secondary device
using the standard error response “?[l/f][c/r]”.
The EDSU data string can be made up of any 8 bit values (up to 60 values total values) which
terminate with the [c/r] character. These can be any 8 bit values except [c/r][l/f]. Care should
be taken if the string includes any other ASCII control characters, ( Hyperterminal , PuTTY or
other data interpretation programs might recognize them as formatting commands and
attempt to implement them).
10. Troubleshooting Possible Errors and How to
Fix Them
10.1 Loss of Program
In the unlikely event that a lens experiences a loss of program, the start-up prompt
will appear as a @[l/f][c/r] or @x[l/f][c/r] . If this occurs, the lens will need its program
to be reloaded. Please contact your service provider.
