Load Data Commands Use these commands to load data into the unit‘s encode storage.

A (41H) Load ANSI/ISO standard data for encoding track 1

B (42H) Load ANSI/ISO standard data for encoding track 2

C (43H) Load ANSI/ISO standard data for encoding track 3

ACTION The unit performs the following sequence: Clear the Encode Data storage

for the specified track. Transmit Command acknowledge (“^” 5EH). Wait for download of

the encode data in ASCII, terminated by the ASCII EOT character (04H). If data is good,

transmit acknowledge (“^” 5EH). Else, transmit “*” error response. Note Commands A,

B and C are special cases of the two byte commands a, b, and c. Example: A = a1, B =

b2, and C = c3.

a (61H) Load ISO data for encoding track 1

b (62H) Load ISO data for encoding track 2

c (63H) Load ISO data for encoding track 3

FORMAT 2-byte command – Command character (a, b, c) is followed by an ASCII

number (1, 2 or 3) representing the ISO track format for processing the Magstripe data.

ACTION The unit performs the following sequence: Clear the Encode Data storage

for the specified track. Transmit Command acknowledge (“^” 5EH). Wait for download of

the encode data in ASCII, terminated by the ASCII EOT character (04H).

If data is good, transmit acknowledge (“^” 5EH). Else, transmit “*” error response

j (6AH) Load Passbook data for encoding track 2/3

FORMAT 2-byte command – The command character (j), is followed by an ASCII

character representing the end sentinel used for IBM-Passbook encoding. Only the lower

four bits of the ASCII character are used for the end sentinel. If the <ESC> character is

sent for the end sentinel, then the command is aborted and the unit sends acknowledge

(“^” 5EH).

ACTION The unit performs the following sequence: Clear the Encode Data storage

for tracks 2 and 3. Transmit Command acknowledge (“^” 5EH). Wait for download of the

encode data in ASCII, terminated by the ASCII EOT character (04H).

If data is good, transmit acknowledge (“^” 5EH). Else, transmit “*” error response

Note (1) Use this command when you only want to write passbook formatted data to a

card. Two redundant data fields are encoded on tracks 2 and 3.

(2) Tracks 2 and 3 write data buffers are loaded with the passbook formatted data.

(3) The encoding density for tracks 2 and 3 are always set to 210 bpi when this command

is used and completed.

(4) After this command is completed, arming the unit to write always writes over tracks 2

and 3.

(5) Command is only supported on reader/writer units with tracks 2 and 3.

Reader/Writers that have track 1 and 2 only respond with a Can’t Execute (“~” 7EH).
