APS-M Series 8/16-Port Intelligent Serial Port Management Switch with Internal Modem
The APS-8M and APS-16M 8 or 16-Port Intelligent Serial Port Management Switches provide a convenient means for connecting multiple RS-232 devices for on-site and/or dial-up remote communications. High data throughput, a built-in 56K V.92 internal modem, and full modem and data flow control all add up to make the APS-8M/16M the perfect data switches for today's high speed communications applications.
Versatile Configuration Options
Each APS-8M/16M RS-232 port can be accessed by port number or by user-defined port name, and ports can be individually configured for data rate, parity and flow control. In addition, each port can also be password protected, and the APS-8M/16M's password directory allows definition of up to 32 distinct passwords.

Three Available Port Modes
APS-8M/16M RS-232 ports can be configured for one of three different operating modes: Modem Mode, Any-to-Any Mode or Buffer Mode.

  • Modem Mode:  This mode is used to manage and configure the APS-8M/16M's internal modem, and also allows any other APS-8M or APS-16M RS-232 port to be easily connected to an external modem. The APS-8M/16M supports all hardware control lines typically required by high speed modems.

  • Any-to-Any Mode:  Any-to-Any Mode employs the APS-8M/16M's full matrix capability to connect to any other free port on the switch, without the need to select matching communications parameters for the two connected ports. The Any-to-Any Mode is specifically designed for situations where you need to connect a modem, terminal server or local PC to other asynchronous control ports.

  • Buffer Mode:  A Port configured for Buffer Mode can be used to capture and store a "snapshot" of the last 32K of data received at that port. "Snapshot Data" is stored in non-volatile memory for later retrieval by the systems operator. This is particularly useful when you wish to collect important data or error messages sent to a port during non-connect periods.


Internal Modem
The internal 56 Kpbs V.92 Modem provides dial-in capability. User-defined passwords and a convenient dial-back security feature prevent unauthorized dial-in access to sensitive command functions. User-defined "AT" initialize and disconnect strings assure proper modem configuration and also provide the ability to reset an external modem (using the data timeout) in the event of line disconnection or session lock-up.
