HW - HARDWARE COMMAND
This command controls miscellaneous hardware options, shown in Table 4-6. The data for this
command consists of 8 ASCII bits (“0” = hex 30 and “1” = hex 31).
To execute, send the HW command as follows:
HW 01010101<ENTER> (with data)
or
HW <ENTER> (without data)
When sending data, all 8 bits must be provided. The MICR Reader will execute the command but
it will not reply. The new settings become effective immediately. To make this command
permanent, use the SA (Save) command described at the end of this section.
If no data is sent, the MICR Reader responds with the current settings for HW.
