PORT MANAGER SWITCHES
Modem Communication
You can control the PM Switch either from a local PC directly cabled to it or
from a remote PC across a modem link. Use ProComm
® (or another
communications program) to send commands to ports and to receive and
display status information from them. All devices connected to the Switch’s
ports would have outbound access to the outside world through any
connected modem, but the Switch’s modem ports are password-protected to
restrict unauthorized inbound access to other devices connected to the
Switch.
Configuration Backup
Once you have configured the PM Switch to fit the requirements of your
application, you can save your chosen parameters and options in the form of
an ASCII text file for future retrieval. If the Switch’s configuration is
accidentally altered or deleted, you can use your terminal-emulation software
to reload this configuration file into the unit.
