1 communication interface
The EC320 reading module provides a TTL-232 serial communication interface for communication with the host. Through
the communication interface, it is possible to receive reading data, control the reading module to issue commands, and change
the function parameters of the reading module.
1.1 serial communication interface
The serial communication interface is a common way to connect the reading module to the host device (such as PC, POS,
etc.). When the reading module is connected to the host using a serial cable, the system uses the serial communication mode
by default. When using the serial communication interface, the communication module and the host device must be completely
matched in the communication parameter configuration to ensure smooth communication and correct content.
Serial output
The serial communication interface of the reading module uses a TTL level signal (TTL-232), which adapts to most
system architectures. If the system needs to use an RS-232 form of architecture, it is necessary to add a conversion
circuit externally.The serial communication interface of the reading module uses a TTL level signal (TTL-232), which

The default serial communication parameters of the reading module are shown in Table 2 1. The baud rate of the
reading module can be modified by the serial port command, but the remaining parameters cannot be modified.
