ENCODE EXAMPLE
To encode “ABCDEFG” on Track 1 and “123456789=112233” on Track 2 and keep Track 3 the
same, the data to the encoder is as follows:
Request:
The STX character shows on the computer’s screen as a happy face (on some systems it might
appear as $02). The ETX character shows on the computer’s screen as a heart (on some systems
it might appear as $03). It is not necessary to send a carriage return after the ETX. With this
command, Tracks 1 and 2 will be encoded. Track 3 will be left as it is. The {BCC} is required
only if that option is enabled.
Response:
After a good encode, the MT-85 will return the data that was read from the tracks being encoded:
If there is an error in any of the encoded tracks, a NAK message will be sent:
