APS-8M / APS-16M Asynchronous Port Switches; User’s Guide

Modem Communication

The APS-8M and APS-16M can both be controlled by a local PC that communicates with the unit via cable, or controlled remotely via external modem. Hyperterminal (or another communications program) is used to send commands to connect ports or display status.

Configuration Backup

Once you have conﬁgured the APS-8M or APS-16M to ﬁt your application, parameters and options can be saved to an ASCII text ﬁle on your PC. This allows you to quickly restore user-selected parameters if the unit conﬁguration is accidentally altered or deleted. Saved parameters can also be uploaded to other APS-8M or APS-16M units. This allows rapid set-up when several units will be conﬁgured with identical or similar parameters.

APS-8M and APS-16M Units

This User's Guide discusses both the APS-8M and APS-16M. Throughout this User's Guide, both units are referred to as "APS-8/16M." The APS-8M includes seven RS232 ports and an internal modem, and the APS-16M includes sixteen RS232 ports and an internal modem. All other features function identically.
