1. RS-232端口

PES-2606的RS-232端口是由D-SUB 9针 Male(公) 接口组成。 引脚图如下。


序号 名称 说明 级别 I/O 布线
1 DCD Data Carrier Detect RS-232 In Optional
2 RXD Receive Data RS-232 In Required
3 TXD Transmit Data RS-232 Out Required
4 DTR Data Terminal Ready RS-232 Out Optional
5 GND Ground Ground - Required
6 DSR Data Set Ready RS-232 In Optional
7 RTS Request To Send RS-232 Out Optional
8 CTS Clear To Send RS-232 In Optional
9 RI Ring Indicator RS-232 In Optional


Slave ID用于PHPoC扩展板区分各个智能扩展板。 因此连接在PHPoC扩展板上的各个智能扩展板需要使用其固有的Slave ID。 Slave ID可设定1至14中的其中一个。如下调整4个的DIP switch来设定。


3. LED

此板有9个9 LED。

区分 数量 类型 颜色 动作说明
STS 1 SMD red ID setting is normal > repeats on / off every 1 second
ID setting is incorrect > blinks fast
TX 2 DIP, SMD green blinks when sending data to the serial port
RX 2 DIP, SMD yellow blinks when receiving data to the serial port
CTS 1 SMD yellow ON when CTS signal is ON
RTS 1 SMD green ON when RTS signal is ON
DSR 1 SMD yellow ON when DSR signal is ON
DTR 1 SMD green ON when DTR signal is ON
