2-1.RS-232 Serial Interface串口

RS-232 is developed according to the EIA standard asynchronous transmission, the specifications are as following:

串口是根据EIA开发标准异步传输,规格如下:

• Ø        Data transmission数据传送:  serial interface串行接口
• Ø        Synchronization同时性: asynchronous异步
• Ø        Signal Level信号电平: RS-232 level, logic 1:-5.4v, logic 0：+5.4v串口电平,逻辑1:-5.4 v,逻辑0:+ 5.4 v
• Ø        Hardware Flow Control硬件流控制:   None无
• Ø        Baud rate波特率:    2400pbs to 115200pbs is optional（400 pbs 115200 pbs是可选的）
• Ø        Data word length数据字长:    8 bits
• Ø        Stop bit停止位:    1bit
• Ø        Parity奇偶校验:  None无

Users can get the current baud rate from the printer self-testing page.用户可以从打印机自我测试页获得当前波特率。

Serial cable串口线: We have made the cable specially using mini port like Mini USB port which connects the printer .The following picture shows the signal definition of the RS-232 Serial interface:我们已经制作专用迷你端口的数据线,像迷你USB端口连接打印机。下面的图片显示了串行接口的信号定义

The connection between the printer and host follows the following rules:打印机和主机之间的连接遵循以下规则:

However, the printer usually works only on receiving data, it doesn’t have to respond anything back to the host , then TXD signal can be ignored , and then the connection can be sampled as following:然而,通常打印机只能接收数据,它没有回应任何信号给主机,这样TXD信号可以被忽略,于是连接可以抽样如下

2-2. Bluetooth Connection蓝牙接口连接

Bluetoothis aproprietaryopenwirelesstechnology standard for exchanging data over short distances (using short-wavelength radio transmissions in theISMband from 2400–2480 MHz) from fixed and mobile devices, creatingpersonal area networks(PANs) with high levels of security.

蓝牙是一个专有打开无线技术标准在短距离交换数据(使用短波无线电传输在ISM波段从2400 - 2480 MHz)从固定和移动设备,创建个人高水平的安全区域网(PANs)

2-2-1. Bluetooth specification蓝牙参数

Using blueCore4-Ext chipset, fully compatible with Bluetooth 2.0;

使用blueCore4-Ext芯片,完全兼容蓝牙2.0;

2-2-2. Use “AT” command to modify Bluetooth Module’s parameters用“AT”命令分析蓝牙模块参数

Notice:The following changes can’t be done by user, these should be done in factory by Manufacturer. So if user wants to change these parameters, please inform our sales person before ordering our printers.

注意：用户不能随便更改参数，参数是由产生商更改。所以如果用户需要改变参数时，在购买之前请通知我们的相关销售人员。

Modify name---Send character string “AT+NAMEXXXX, feedback “Okname”;

修改名字------发送字符串“AT+NAMEXXXX,返馈回来“Okname”

For example, if you want change name to “LY58”, please send string “AT+NAMELY58”.

比如，如果你想更改名字为“LY58”，请发字符串“AT+NAMELY58”.

Modify PIN code--- Send character string “AT+PINXXXX, feedback “Oksetpin”;

修改蓝牙配对码－－－发送字符串“AT+PINXXXX,返馈回来“Oksetpin”

For example, if you want change PIN code to “8888”, please send string”AT+PIN8888”.

比如，如果你想更改蓝牙配对码为“8888”,请发字符串”AT+PIN8888”.

(Note: Default PIN code is “1234”, you only can reset PIN code with four figures.)

注意：默认蓝牙配对码是“1234”，你只能重新设置4位数蓝牙配对码。

Clear Bluetooth address--- Send character string “AT+CLR00”, feedback “Okclear”;

清理蓝牙地址------发送字符串“AT+CLR00”, “AT+CLR00”返馈回来“Okclear”;

Modify baud rate---Send character string “AT+BAUDX, feedback “Ok+current baud rate”;

修改波特率------发送字符串“AT+BAUDX”，返馈回来“Ok+current baud rate”;

X represents the baud rate code, as following:

X代表了波特率的代码,如下
