RESET DEVICE
The Reader will always be reset when power (DTR) is applied (hardware reset). It can also be
reset programmatically with a Reset (RS) command. This command can be used after changing
the setting to activate the new values:
<ESC>RS<CR>
After sending the <ACK>, the Reader will perform a soft reset and, if the function is enabled
(SA-6), will transmit the sign-on ID message:
<ACK>21088830B03<CR>
Note that the carriage return (CR) will be included in this response only if the function is enabled
(SB-0).
VERSION REQUEST
In order to determine which device is connected, the application can send a Version Request
(VR) command to the Reader:
<ESC>VR<CR>
The Reader will respond with an ACK and then will transmit the firmware part number and the
corresponding version in a format like this:
<ACK>21088830B03<CR>
Note that the carriage return (CR) will be included in this response only if the function is enabled
(SB-0).
UPLOAD COMMAND
The Upload (UP) command is used to move any modified properties from temporary storage into
the flash memory. This only needs to be done once after all changes have been made.
This method of updating the programmable settings allows all parameters to be modified in
anticipation of the next reset. Thus, a series of switch commands (including the sentinel values
described below) can be sent to the Reader without affecting any operation. The set of
configuration commands should be followed by an Upload (UP) command to transfer all settings
into flash. Finally, the Reset (RS) command can be sent to validate that all changes have taken
place. After the RS command, any changes to communication parameters will become effective.
