布局
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 |
2. SLAVE ID开关
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 |
