Serial Interface
The serial interface allows on-site and off-site communication with the system. Using this
interface is the only way to view reports and to change system parameters. If your site doesn't
have telephone service, you cannot communicate with the system remotely (that is,
off-site ).
To use the interface locally , you need:

A computer

Communications software, which is installed on the computer

A cable from the computer to a communications port on the System Interface board
To use the interface remotely , you need:

A computer

Communications software, which is installed on the computer

A modem, which is connected to the computer

A nonswitched analog telephone line, which is connected to the computer's modem

Another modem, which is connected to a communications port on the System Interface
board

Another nonswitched analog telephone line, which is connected to the modem in the
SmartScanIS enclosure
This chapter describes the serial interface for the SmartScanIS. It covers how to enter or
change the system parameters. The next chapter tells how to use the serial interface to
produce reports.
It is necessary to go through a complete setup the first time a SmartScanIS is installed at a
new site. (If this is a double-track site, you need to do this for the other SmartScanIS.) After
that, the Processor board (in the Controller module) retains the setup information. During a
power outage, no setup information is lost if the battery on the Processor board is operative. If
this battery isn't operative during the power outage, the only setup information that is lost is the
date and time.
