Code Activated Port Switches

WTI's code activated port switches allow access to multiple RS-232 or RS-422 ports from a single PC or host computer. Our CAS series switches are designed for a wide variety of data collection and broadcast applications. Common CAS applications include collecting data from a series of sensors or scales, broadcasting data to multiple display monitors, loading program data to NC or robotics equipment, and sending print jobs to bar code or label printers.

CAS-41A & CAS-81 4 and 8 Port Code Activated RS-232 / RS-422 Port Switches The CAS-41A and CAS-81 Code Activated Switches are designed for data distribution applications, where a single RS-232 device requires instantaneous, high-speed access or transmission to multiple RS-232 peripheral devices. Port connections are selected using simple ASCII commands sent to the CAS using your communications software. If longer transmission distances are required, our optional RS-422 output channels can provide send/receive distances up to one mile. More Information

CAS-161A 16 to 64 Port Expandable Code Activated Port Switch The CAS-161A Code Activated Switch is ideal for applications that require high-speed access or transmission to up to 64 RS-232 devices. The modular design of the CAS-161A allows the unit to easilly expand from 16 to 64 RS- 232 ports. If additional ports are required, expansion units are simply added to the CAS-161A master unit. The CAS-161A monitors data received at the Master Control Port and watches for the ASCII command sequence to select the desired port. When a port is selected, data and flow-control signals pass between the Master port and selected Output port. A convenient broadcast feature allows the CAS-161 to broadcast to all 64 possible ports. If longer transmission distances are required, our optional RS-422 output channels can provide send/receive distances up to 5,000 feet. More Information
