FSL Setup via PC’s Parallel Port

Deactivating the Y249 Engineering Function

The function will be deactivated automatically after timeout on the
share port (timeout is defined in Y100 Port Sharing Option).

Limitations when Y249 is active

1. Escape sequences must be in HEX
Unprintable characters (i.e. Escape characters) must be defined
in HEX notation if they are to be part of the setup print job.
2. FSL Functions (limited/not supported)
All twinax FSL functions (except Y96 Font Change Simulation)
are available. For Y2 (LPI) and Y3 (CPI), only the default values
will be updated: i.e. LPI 6 (for Y2) and CPI 10 (for Y3).
4. Non-operative Test FSL functions
T1 On-line HEX dump
T3 ASCII dump
T1 (online HEX dump) will produce on-line HEX dumps of data
from the twinax line. T3 will produce ASCII dumps from the
twinax line.
8.1. Updating firmware
The ida 812-1x MIO firmware (complete firmware) may be updated
via share port. Firmware is downloaded from the share port using the
ESC P2 command (only available in Engineering Mode - Y249).
If errors are detected, the downloading will be terminated and an
error message will be printed if possible. If serious errors occur
during programming, the firmware has to be downloaded again via
the share port.
The downloading of firmware is considered complete if no data from
the host is received within 30 seconds. The interface will then make
a soft reset.
