Time Relay with RS-232 Interface

Connect the Taralist Controller to Your Computer's Serial Port or USB port with an adapter
The Controller Mounts as a Virtual COM Port on Your PC
Time Activated Control is Effortless!

Our New ZRS Serial Taralist Relay Controllers make it easier than ever to add time activated controlled switching to your most demanding computer control applications.  Simply connect to your computer and this controller mounts as a COM Port on your PC, allowing easy programming from any language that supports serial communications.

This Taralist controller connects to the Serial port of your computer and requires a 12VDC Power Supply (available at checkout).  Once powered up, the Taralist controller waits for a command.  A command consists of a few bytes of data.  Usually between 2 and 6 bytes.  Once the command has been received, the controller processes the command, and sends you back ASCII character code 85 to signal the completion of your command.
