3.3. COM Port Selection

By default, COM1 is used when the demo software is opened. If the user prefers to communicate
with the reader through different serial port or close the port, the port setting can be modified in Port
Setting menu.

3.3.1. Help

The Help menu displays the demo program's version information.

3.3.2. Manual Command and Reader output

In this field, a user can manually type commands to send to the reader. Click Send Command to send
the command to the reader. The Command structure is described in next section.

3.3.3. Manual Command Format

Manually input commands and send settings to the device.
Command Format:
<STX> <ATMEL Function ID> <Len1> <Len2> <STX> <Command_Data> <ETX>
<LRC><ETX> <LRC>
where: <STX> = 02h, <ETX> = 03h, <ATMEL Function ID> = 54h,
<Len1> and <Len2> are two bytes length in SPI Protocol
<LRC> is one-byte XOR value calculated from <STX> to <ETX>.
The user is only required to enter the Command_Data parameter; the demo software automatically
encapsulates the ATMEL Protocol and SPI Protocol.
For example:
Read Firmware Version
1. Enter "52 22" in the Manual Command / Reader Output window
2. Click Send Command. The demo software will encapsulate ATMEL Protocol's STX,
ATMEL Function ID, two bytes length, SPI Protocol's STX, ETX, LRC, and ATMEL
Protocol's ETX and LRC.
