Using the digital I/O interface

Overview

The operation of an SM-Series module is remotely controlled through two interfaces. In order to simplify the task of the user, a module is controlled using simple commands such as DC-voltages and single digital lines.
Despite high-pin count connectors, this choice to provide a straightforward interface should be time-efficient during rapid prototyping phases.
This application note reports several ways to control an SM-Series module over its digital interface.

Overview

Since the SM-Series modules can not have more than 4 or 5 coaxial connectors on their front panel, these connectors are reserved for RF and specific I/O signals .  The remaining signals of the module, such as the digital control lines or the analog inputs, are connected to their respective stack-through header. While some of these signals are used by other boards, the user may need to access an analog or digital I/O using a BNC connector.

The SMZ110 module allows the user to connect an analog or digital I/O  to a  front panel BNC. Up to 5 BNCs are available on front panel and every I/O of the analog and digital interface can be wired.  The connections between the BNC and the I/O are made using small  jumper wires. In addition, component footprints are provided to implement passive filters.

Like all SM-Series modules, the SMZ110 is shipped with the schematic diagrams of its electronic circuitry providing all required information for advanced users.
