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. WTI also manufactures a complete line of intelligent data matrix switches for remote or local serial console access via Telnet, local terminal or dial-up modem communication.

CAS-41 & 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.

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.
