CP290 Interface Connection Problems.
If you are having problems connecting to the CP290 interface then follow
these steps below.
- Make sure the com port setting in the configuration matches the com
port you use for the interface.
- Make sure you have all the included files present in your HOUSE290
directory.
- If you have Ray Gwinn's SIO com drivers, use the included PMLM (Poor
Man's Line Monitor) to monitor data exchange between the Comm Engine and
CP290. Use HOUSE/290 to send out a request to read time for example. The
CP290 should respond with data. You can observe this data with PMLM and
that may help in troubleshooting.
- If you are using Ray Gwinn's SIO com drivers, check if the baud rate
is locked for the particular com port you are using with the interface.
Unlock it so the Comm Engine can change the baud rate to 600. From the SIO
reference, it states:
Locked Baud Rate
Placing a colon and a baud rate following the communications port, eg
(COM1:38400,3F8,IRQ4), causes the port to be locked at that baud rate.
No program, OS2 or DOS, is allowed to change the baud rate.
- Try the standard COM1 or COM2 ports if you have problems with any other
com ports like COM3 - COM8. Also, remove any serial cable extensions or
adapters and connect the interface directly to the computer.
- Try using a different computer or different com port to access the
CP290.
- Download my X-10 Comm Tester program from my web page. This
program was specifically written to help troubleshooting communications
problems with the CP290 interface.
- E-mail me and I will try to help you out. (Eventually registering HOUSE/290
will give me extra incentive too!).
