12 Working with Third-party
Communication Diagnostics
The communications for the protocols that use the serial interfaces (RS-
232 and RS-485) on the Xenta 913 can be monitored using HyperTer-
minal or on the Xenta 913 web site.
To monitor the communications for the protocols that use the Ethernet
network, you connect a network listener.
12.1 Connecting a Diagnostics Terminal
Due to differences in the implementation of the protocols in third-party
products, it is very unusual for the communication between a Xenta 913
and another device to work properly when first tested, so a diagnostics
test is most probably required.
A web browser such as Internet Explorer can be connected to the
Xenta 913 web server and used to monitor and control the target I/O
values using the previously-created values pages. If, however, the val-
ues do not update, or appear incorrect, it can be very difficult to diag-
nose the problem from the Values pages alone. For this reason the
Xenta 913 includes a communications log that can be used to monitor
the actual communications traffic with the target system.
The web browser can be used to control and view the communications
log. However, this process is generally not as easy or as effective as
using a PC terminal program like HyperTerminal. So if diagnostics are
necessary, and it is possible, connect a PC to the RS-232 B channel of
the Xenta 913 using the appropriate cable from cable kit 007309200.
This connection is only required during initial diagnostics, and can be
removed when completed.
• Once the terminal is connected, power up the Xenta 913 and asso-
ciated equipment. If the terminal has been correctly connected,
then the boot-up and Xenta 913 startup messages should appear on
the terminal. If not, then refer to the documentation of both the ter-
minal program and the Xenta 913 to try and locate and correct the
problem. However, terminal connection problems are unlikely at
this stage because the terminal program was probably used to set
the Xenta 913’s initial IP address. For more information about
using HyperTerminal, see TAC Xenta 500/700/911/913, Product
Manual.
