Property Description
Use this password
to logon to an
instrument
If checked, APIcom will use the specified password to logon to the instrument
when establishing a connection. Most of API’s instruments have some password
mode in which the instrument will only accept commands after a password has
been submitted. Also refer to the section titled Modems below.
2.5.2. Configuring Sites
APIcom maintains a list of all the sites, which can be accessed by selecting Settings-Sites, as shown
below. Each site represents one physical site or one physical port on the host PC, at which multiple
instruments may reside. APIcom maintains separate properties for each site. To modify the properties
for a site, double-click on the name, which will display the dialog box shown in Figure 2-11.

The site maintains all of the information necessary to connect to a particular site, including connection
type (direct cable or a modem), telephone number, connection speed, etc. One site may be shared by
several instruments. Since each site requires one COM port, modem or ethernet address on the
computer, a user may only connect simultaneously to as many different sites as there are COM ports or
modems. Ethernet connection allows multiple sites with different IP addresses and is limited only by the
bandwidth of the host computer's TCP/IP connection. However, a user can connect simultaneously to
many different instruments at a single site, using either the API multidrop feature or a code-operated
RS-232 switch. Regardless of the number of COM ports or modems, a user can specify multiple sites for
the same port. In this case, only one site can be used at a time. A click on
will reset all of
the properties to their default values. The table below describes the site connection properties shown in
Figure 2-11.
