General Command
The general command of the reader is for daily transaction purpose. Depending on the reader set
for which protocol, the command can be sent by using one of the following protocols: USI0, or USI2
(default).
USI0 – the simplest data format without the header, the trailer or the BCC. The reader relies on a
100ms timeout to determine that a command is received.
USI2 – with 01h (SOH), data length and BCC
