USB Contact Closure Monitoring

With this Scan Series Controller you can monitor Contact Closure Inputs using a computer.  With minimal programming, data collection and control from a single controller allows any computer to talk this device from anywhere on the network.  The SCAN Series command set allows you to read anywhere from 1 to 32 banks of 8 inputs in a single query.  A single bank contains 8 inputs.  Reading 32 banks will report the status of 256 inputs.  It doesn't stop there, because we are focused on relay control you can add relays to the board (up to 256) and control them using the data collected from the inputs.  Remember these are contact closure inputs ONLY no voltage can be applied to these inputs.  Simply connect to your computer and this board mounts as a Virtual COM Port on your PC, allowing easy programming from any language that supports serial communications.

Mounts as a COM Port

This ProXR series controller connects to the USB port of your computer and will mount as a COM port on your PC.  USB Drivers will most likely be needed and can be found in the resources section to the right and will also be available in the Base Station Software.  Once powered up, the controller waits for a command.  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 sends you back ASCII character code 85 to signal the completion of your command.

ZUSB ModulesUSB Relay ZUSB Module

This board is equipped with a ZUSB Module.  The ZUSB communications module adds USB communications to the board.  The ZUSB module is powered from the USB port of your computer and includes a 6' USB Cable.  The board itself will require 12 volts of power and can be hard wired or you can purchase a "wall wart" type Power Supply at checkout.

Sending Commands

Base Station Software is available at no charge to get you up and running fast (more on Base Station below).  Once powered up, the controller waits for a ProXR command.  A command consists of a few bytes of data in numerical format (ProXR Enhanced Command Set) 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.  When a command was sent to read the status of the contact closure the status is sent back.
