are fixed to 8, N, 2, using the ESA command, regardless of the settings for these
parameters prior to issuing the ESA command.
For example: If synchronization between the host and reader was achieved at
"9600,7,E,1", but the host issues an ESA command with a requested baud rate of 19200,
then it is necessary for the host to change communications parameters to "19200,8,N,2",
not "19200,7,E,1". When the host issues the Product Reset Command (PRC) causing the
product to exit ESA mode, it is required that the host change the communication
parameters back to the values used prior to synchronization, unless, the RS-232
parameters were altered using setup commands while in ESA. If the parameters are altered
using a SMC while in synchronization, it is necessary for the host to communicate using
these new RS-232 parameters subsequent to exiting ESA mode.
Accepted Command (ACC = 0x06)
Indicates that the command has been accepted and is running or has been completed.
Interactive Mode Command Error Command (IEC = 0x07)
Indicates that the IMC is not active.
Download Application Program (DAP = 0x09)
DAP programs are used to download user application programs from the host to the
product and to upload user application programs from the product to the host.
Interactive Mode Command (IMC = 0x0A)
IMC is one of the remote control protocol command types that is used to control the
product through the physical interface. A special IMC must be sent to activate this
mode. See “Interactive Mode Commands (IMC = 0x0A)” on page 4-30 for detailed
IMC structure.
Setup Mode Command (SMC = 0x0D)
The SMC is used to configure the product’s parameters stored in NVM.
Product Event (PEV = 0x0E)
This command is generated by the product if an internal event occurs (e.g., time-out,
trigger status, etc.). This command is only returned in interactive mode.
