The SDS511 dual port adapter allows two communication devices to be connected to one datalogger CS I/O port. This allows you to connect both a modem, such as the COM310, on port 1 and another device, such as a PDA, on port 2. Communications are determined on a “first come first served” basis.
To secure the SDS511 to the backplate of an enclosure, purchase the SDS511 Mounting Kit. The kit includes the mounting bracket and hardware, and is not included with the SDS511 purchase.
