概览
SDS511 允许两台通讯设备被连接在同一台数据采集器的CS I/O端口上。通信基于先到先得规则（例如适配器不支持两台设备间或两个CS I/O端口同时发生的通信）。 因此，SDS511 建议用于仅能通过CS I/O端口访问的设备。
优势与特点
- Allows two communication CS I/O devices to be connnected to one data logger CS I/O port
- Recommended for devices that access the CS I/O port intermittently for a short duration
- Supports modem enabled (ME) device

技术说明
The SDS511 dual port adapter allows two communication devices to be connected to one data logger CS I/O port. Communications are determined on a first-come-first-served basis (that is, the adapter DOES NOT support concurrent communications between the two devices and the CS I/O port). Therefore, the SDS511 is recommended for devices that only access the CS I/O port intermittently.

Additional Compatibility Information
Supported Devices
The SDS511 supports modem enabled (ME) devices. The ME devices connect to the SDS511 via 9-pin serial cables supplied with the product. Some of our older cables are also compatible, namely the SC12 and 10873 cables. Please note that you can only use one of our newer, black, molded SC12 serial cables. However, you can use one pn 10873 cable and an SC12 cable.
Data Logger Considerations
The SDS511 is typically not used with our newer data loggers.
