2.2.2 RS-232 Communications Port Properties
Figure 2-10 shows the properties of the Communications Port.
Figure 2-10 Com Properties: Com Settings tab
The Baud Rate is set by default to 115200 for RS-232 communications. This is the
fastest rate possible (at this time) in the XTC/3 Controller.
The Retry Limit is the number of times the program will try to reestablish
communications with the XTC/3 Controller after a communication error. The default
(0) should be adequate for most installations, however, if the Controller goes off line
frequently, try setting the Retry Limit to a higher count.
The Timeout is the number of milliseconds the communication module will wait for
a response from the controller. Normally, the default value (5000) is adequate and
should not be changed. Setting this value too high will increase the time it takes to
detect a controller which has gone off-line. Setting it too low may cause an error to
be reported when communication commands with long execution times are issued.
Click OK to accept the selections, or Cancel to abort the action. You can also click
on the AutoDetect tab to access the other parameters associated with the Com
Properties for this port.
The Controllers tab provides a list of Controllers configured to communicate with
the software. For RS-232 communications, this list will contain one Controller and
that controller will be automatically detected and added when connected. (See
Figure 2-11 ).
