2 Interface
HBCS2D100U reader provides TTL-232 serial communication interface to communicate with the host.
Through the communication interface, you can receive the read data, send commands to the reader to control,
and change the reader's function parameters.
2.1 RS232 Communication Interface
Serial communication interface is a common way to connect the reader with the host device (such as PC,
POS, etc.). When the reader and the host using a serial cable connection, the system uses serial
communication mode by default. The use of serial communication interface, the reader and the host device
must be in the communication parameters on the configuration to match, in order to ensure smooth
communication and content is correct.
Serial output
The reader's serial communication interface uses the TTL-level signal (TTL-232), which adapts to most
system architectures. If the system requires the use of RS-232 form of the structure, the need to increase the
external conversion circuit.
The default serial communication parameters of the reader are shown in Table 2-1. Among them, the baud
rate of the reader can be modified through the serial port command, but the remaining parameters can not be
modified.
