AXIS 370 Cobra User’s Manual 51
Producing Hexdumps A hexdump is a printout where the input data stream is printed as
hexadecimal byte values rather than being interpreted as characters
and control codes. The AXIS 370 Cobra features two different types
of hexdump modes:
• System hexdump
This mode will trap the input data before the character and
control code conversion. The data is printed as EBCDIC or DBC
hexadecimal values.
• ASCII hexdump
The input data is converted to ASCII hexadecimal values before
printing. This mode is useful if you want to see what printer
control command a certain IBM control code corresponds to.
To produce a hexdump, do as follows:
1. Switch the printer and AXIS 370 Cobra off and on.
2. Set the rotary switch to ‘9’, and wait for approx. 3 seconds
until the SYSTEM indicator starts to flash. You are now in the
Test Mode.
3. Select position ‘4’ for system hexdump, or position ‘3’ for
ASCII hexdump.
4. Repeat your print job. The data will now be printed in
hexadecimal form.
5. Set the rotary switch to ‘9’ when the printout is completed.
The SYSTEM indicator will stop flashing.
6. Select position ‘0’ to resume normal print operation.
