Revised: May 22, 2002 Niagara Networking & Connectivity Guide
Chapter 5 Connecting to an ISP
Configuring Captive ISP on the JACE-4/5
5–16
Notes • With the IspConnection object, the connect/disconnect schedule resides in the
station rather than being managed by the Niagara daemon. Therefore, if the
station on the JACE is not running, the JACE will not follow the disconnect
schedule. For more information, see the “Troubleshooting Connection
Problems” section on page 5-19.
• The IspConnection object can only be used with the captive ISP function, not
with the direct dial function.
The object has one input (sIn or statusIn). To establish a connection, use a schedule
or other binary object to set sIn to Active. To terminate the connection, set sIn to
Inactive. When inactive, the modem will resort to either idle, or listening as
configured in the dialOutOnly parameter in ras.properties.
Note The object passes your connection request to the Niagara daemon, which implements
it on its next cycle. There can be a delay from when the command is issued and the
daemon begins the connection process.
The object also has several output status properties, as listed in Figure 5-2.
Examples
You can connect the statusOutput to boolean or GxText objects, and the state, rate,
and connection outputs to text objects.
Figure 5-4 shows examples of an ISPConnection object in use. Figure 5-5 shows a
simple GxPage containing information from the outputs of the IspConnection object.
Table 5-2 Outputs of the ispConnection object.
