一种智能文本显示设定终端
摘要：
本实用新型公布了一种智能文本显示设定终端，其通过自带的DB9插座与外部设备连接，所述智能文本显示设定终端内部主要包括有CPU、上电复位电路和电平转换电路；所述CPU内设置有容量为8K的第一FlashROM模块、容量为64K的第二FlashROM模块、复位模块以及UART接口模块；所述DB9插座的内部接口与所述电平转换电路连接；所述电平转换电路的第一通信端与所述UART接口模块连接，其第二通信端与所述上电复位电路的输出端共同接入到与门电路，并通过所述与门电路连接到所述复位模块。本实用新型无需工作人员现场操作，无需打开设备外壳就可轻松完成设备终端的升级。
摘要（英）：

The utility model discloses an intelligent text display setting terminal which is connected with peripheral equipment by virtue of a built-in DB9 socket and mainly comprises a CPU (Central Processing Unit), a POR (Power On Reset) circuit and a level conversion circuit; the CPU is internally provided with a first FlashROM (Flash Read Only Memory) module with the capacity of 8K, a second FlashROM module with the capacity of 64K, a resetting module and a UART (Universal Asynchronous Receiver/Transmitter) interface module; an internal interface of the DB9 socket is connected with the level conversion circuit; a first communication end of the level conversion circuit is connected with the UART interface module, and a second communication end of the level conversion circuit and the output end of the POR circuit are jointly connected to an AND gate and are connected to the resetting module by virtue of the AND gate. The intelligent text display setting terminal has the advantages that onsite operations of working personnel are not needed, and the upgrading of equipment terminals can be easily finished without opening equipment shells.
