Selecting The RS-232 Interface
By selecting the
RS232 interface you will be uploading the time schedule to the board through either a DB9 or direct wire interface. Boards on this page are equipped with a
ZRS communications module that adds RS-232 communications to the board. At checkout you will have three modules to choose from with either a DB9
or direct (3-wire) connection. A command consists of a few bytes of data in numerical format usually
between 2 and 6 bytes. Once the command has been received, the controller processes the command and the relay activates.
