Elo TouchSystems 1525L manual write, Data encode command

Section 3. Commands

write

Function	Data encode command.
Syntax	/write data
Errors	/write	94<LF>

Encode is not supported on this device.

/write34<LF>

The data field was in the incorrect format.

/write82<LF>

The write command was canceled.

/write45<LF>

Device in wrong mode (e.g., if /read already issued)

/write60<LF>

Error during write operation (e.g., on MT-95) Remarks The data field is in the following format:

[%an-data?][;n-data?@a-data?][(+n-data?#an-data?!an-data?&an-data)]an-data is alphanumeric data (ASCII characters ‘ ‘ to ‘_’ (0x20 to 0x7f)) n-data is numeric data (ASCII characters ‘0’ to ‘?’ (0x30 to 0x3f))

The data should not contain the end sentinel character (?).

If the application sends data for an alphanumeric track that contains lowercase characters (ASCII values beyond 0x60), they will be capitalized if capitalize =

1. To disable this and send the data as-is to the device, set the capitalize property to 0. The three sub-sections of the data string represent the three tracks on the magnetic card. The data for each track begins with a start sentinel character, which defines both the track number and the data format for the track:

%identifies track 1 (7-bit alphanumeric)

; identifies track 2 (5-bit numeric)

@ identifies track 2 (7-bit alphanumeric)

+ identifies track 3 (5-bit numeric)

! identifies track 3 (CA Driver License)

# identifies track 3 (alphanumeric, AAMVA)

& identifies track 3 (7-bit alphanumeric)

Note that any or all of the data may be missing, but the order of the data for the tracks must always be in order (1, 2, 3). A missing track is interpreted as “don’t write” for the data encode command – that track will not be overwritten by the encode operation.

The response sent for this command is: /write status.

status is 00 if the encode succeeded and non-zero if it failed. See the definitions of the status values in Appendix C. Status Codes.

Example Encode tracks 1 and 2:

Command	/write	%B12345^TEST^0000?;12345?<LF>
Response	/write	00<LF>
