1. Introduction
WTI’s APS-8M Asynchronous Port Switch allows reliable, high-speed
connections between PCs, modems, and other devices using dissimilar baud
rates, parity, and flow control. The APS-8M supports communication at
speeds up to 115.2 Kbps, and features full RTS/CTS hardware handshaking
and a 33.6K V.34 internal modem. Lightening-swift data throughput and full
flow control make the APS-8M the perfect data switch for today’s high speed
communications applications.
Versatile Connectivity
Up to seven different devices can be connected to the APS-8M without the
need to select a common baud rate or parity. Each port can be individually
configured for specific baud rates, parity, handshaking, and various other
parameters and options.
Easy Set-Up and Operation
Configuration of the APS-8M is simple. A menu system is used to select
communications parameters, and enable or disable options. The APS-8M
can easily adapt to the requirements of almost any data communications
application.
Password Protected Connection and Command Access
The APS-8M provides two levels of user security; the Supervisor level and
the Non-Supervisor level. The Supervisor level, which is intended for use by
system managers and other administrators, provides complete access to all
port connection / disconnection functions, operating features and configuration
menus, and also allows access to any port on the switch. The Non-Supervisor
level is ideal for co-location applications, since users are only permitted to
view status and connect to the ports allowed by their password.
Internal Modem
The APS-8M features a 33.6K v.34 Internal modem; allowing easy, convenient
out-of-band access to configuration and control functions.
Non-Volatile Memory
If power to the unit is lost or interrupted, the APS-8M’s non-volatile memory
will retain user-defined parameters and port connections.
