RS-232 Data Control and Monitoring

	AFS-16 Automatic UTP Fallback Switch for Digital or Analog Data Lines Network disasters are impossible to predict, but can be effectively controlled with the AFS-16 Automatic Fallback Switch. The AFS-16 monitors activity on primary hardware lines. If line status changes, the AFS quickly responds and re-routes data signals to a backup line. Lost data and downtime is cut to a minimum. The AFS-16 is ideal for switching RS232, RS422/485, Ethernet/UTP or telephone lines. More Information
	AND-1 Alarm Notification Device The AND-1 monitors ASCII "error" or "cry-for-help" messages, and/or hardware signal levels generated by your data equipment. When a problem is indicated, the AND_1 can call your pager and display a message that describes the problem. In addition to pager notification, the AND-1 can also send an alarm report to a remote printer, or trigger an audible alarm in your security command center More Information
	APS-4, APS-8, APS-16 High Speed Buffered Console/AUX Port Switch The APS high speed Asynchronous Port Switch provides a convenient means of connecting multiple RS-232 devices for on-site and dial-up remote communications. Rapid data throughput and full modem and data flow control make the APS the ideal data switch for today's high speed communications applications. The APS features sixteen individually configured ports. Each port can be assigned its own baud rate, parity, flow control, and other communication parameters. The APS automatically converts these parameters when dissimilar ports are communicating. User-defined passwords protect access to restricted ports. More Information
	DB-2 RS-232 DataBooster II The DataBooster II (DB-2) is a compact, low cost RS-232C compatible signal booster that extends normally limited transmission distances between devices conveniently and economically. The DB-2 provides both signal regeneration and line conditioning. More Information
	LD RS-232 to RS-422 Converter Line Driver With the LD series line drivers, which convert RS232 signals to industry standard RS422 unbalanced lines, your in-house data transmission distance can be extended beyond the standard limitation of RS232. Using inexpensive telephone type twisted pair wiring, you can achieve data rates in excess of 56K and transmission distances up to 5,000 ft. In addition to speed an distance, RS422 unbalanced lines have excellent immunity to electrically induced noise caused by electrical interference which could produce data errors if using standard RS232 circuits. More Information
	SG-232 Dial Back Modem Security Gateway The Security Gateway is a firewall for dial-up phone access. It provides a barrier against unauthorized access to any RS-232 device. It can be used in a dial-back mode with up to 240 numbers and passwords. These passwords are stored in battery backed memory and are secure against tampering by jumpers. The number of tries can be controlled so protection against "dictionary hacking" is exceptionally good. More Information

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

Intelligent RS-232 Matrix Switches

Our RS-232 Matrix Switches provide an intelligent solution for applications that require port to port switching or a data PBX with buffer capabilities.

MDS-8 & MDS-16 8 and 16 Port Serial Matrix Switches with Buffer Mode and Intelligent Features MDS series data switches provide a convenient means for connecting multiple RS-232 devices, collecting and polling data from remote sites and multiplexing data from multiple input sources. Each MDS port can be individually configured in one of three distinct operating modes; Any-Port to Any-Port Mode, Buffer Mode, and Mux Mode. More Information

CPM-6400 Eight to 64 Port Expandable Intelligent Data Matrix Switch The CPM-6400 matrix switch and data PBX is designed for any application where multiple ports need connection to a variety of other RS-232 devices. The CPM-6400 allows network managers to access multiple RS-232 control ports or console ports on network hardware at remote locations. This provides a cost-effective means for out-of-band device management in a WAN environment. The unit is also ideal for basic RS-232 port contention applications. Each CPM port can be individually configured; baud rate, parity, and other parameters are automatically converted to allow communication between dissimilar ports. More Information

RS-232 Data Concentrators & Data Broadcast Units

Our Data Concentrator and Data Broadcast products are designed for applications where data from multiple sources is multiplexed to a single RS-232 port, or data from a single source is simultanesously distributed to several peripheral devices.

SDC-61 Serial Data Concentrator The WTI SDC-61 Serial Data Concentrator provides a convenient means for multiplexing data from several sources, or broadcasting data to multiple peripheral devices. The unit is software independent and easy to configure. Typical applications include bar code or point-of-sale input to a common host PC, data input from multiple scales or digital sensors, or concentrating data from multiple time and attendance terminals.

DBU-41 & DBU-41A Data Broadcast Units WTI data broadcast units are ideal for applications that require sending copies of data to remote display monitors, video terminals or multiple printers. Our DBU units can also send duplicate data for fail-safe backup or redundant storage purposes. Data sent to the DBU's master port is filtered, the signals are boosted, and the data is sent out all 4 or 8 terminal ports. Two different DBU models are available; the standard DBU-41 rack mount model, and the DBU-41A stand alone model. More Information
