The APS-16 and APS-8 high speed Asynchronous Port Switches provide a convenient means of connecting multiple RS-232 devices for on-site and dial- up remote communications. High data throughput and full modem and data flow control make the APS the perfect data switch for today's high speed communications applications.

Each port can be individually accessed by port number or assigned a port name for easy port selection. Ports are individually configured for data rate partiy and flow control, and each individual port can be password protected. Each APS-16 port can be configured to one of 3 modes of operation: Modem, Any-to-Any or Buffer Mode:

"Modem Mode" is used when the APS-16 is connected to a standard external modem. All hardware control lines required by high speed modems are employed by the APS-16. Ports set in Modem Mode are also password protected, and have the ability to reset the external modem (using a data time-out), in the event of a line disconnect or lock up.

"Any-to-Any Mode" uses the full matrix capability of the APS-16 to connect to any other port on the switch. Ports in the Any-to-Any mode can also be connected in third party combinations by separate ports with supervisor rights. This mode of operation is required if the user needs to connect a modem, a terminal server and a local PC between a number of separate async control ports.

"Buffer Mode" of operation sets individual ports for the collection and storage of "snapshot" data, which is the last 32k received by that port. This "snapshot" of data is stored in non-volatile memory and can be invoked by the systems operator at any time. This is particularly useful in the event that data sent to specific ports during non-connect periods is of importance.
