1. Introduction


WTI's APS-16 Multipurpose Data Switches provide a convenient means for connecting PCs, modems, and other devices running at dissimilar baud rates, and collecting data from multiple sources.

Versatile Connectivity

Up to 16 different devices can be connected to the APS-16 without the need to select a common baud rate or parity. Each port can be individually configured for specific baud rates, parity, handshaking format, and various other parameters and options.

Collecting Data from Multiple Sources

The Buffer Mode allows the APS-16 to collect data from up to fifteen different devices and store that data for later retrieval. The APS-16 provides 32K of buffer memory per port.

Easy Set-Up and Operation

Configuration of the APS-16 is simple. A menuing system is used to select communications parameters, and enable or disable options. The APS-16 can easily adapt to the requirements of almost any data communications application.

Limited Command Access

The APS-16 is ideal for situations that require limited access to important commands. Each port can be configured to allow access to all commands (Administrator), or only allow access to basic commands (User). In addition, the APS-16 also provides a Passive Mode which allows connection to other ports, but does not allow access to command functions.

Modular Design

DB9 jacks provide quick, easy connection to computers, modems, and other LAN hardware. The APS-16 is compact and takes only one rack unit (1.75 inches) of vertical rack space.

Modem Communication

The APS-16 can be controlled by a local PC that communicates with the unit via cable, or controlled remotely via external modem. ProComm® (or another communications program) is used to send commands to connect ports or display status.

Configuration Backup

Once you have configured the APS-16 to fit your application, parameters and options can be sent to an ASCII text file and saved for future retrieval. If configuration is altered or deleted, parameters can be reloaded using your communications program.
