Verbatim® Modbus Interface Module is capable of 32, 64, or 96 Points. This field retrofit option is available for use with the Verbatim® and Verbatim® Secure Front Panel. The Modbus option is a standard feature of the Verbatim® Gateway. A Verbatim® Daughter Card Assembly must be purchased for a Verbatim® or a Verbatim® Secure Front Panel autodialer when ordering Analog Channels, Remote Supervisory Control, Verbatim® Modbus Communications, Local Data Logging, Central Data Logging, or SCADA. Only one card is required regardless of the number of options. A Daughter Card is a standard item on the Verbatim® Gateway. (If you are purchasing this option for an exisiting Verbatim® serial number V10788 or higher then you will also need the Front Door upgrade.)
