(A)
Did not get the Card Identification message, instead got the message below upon launching the PC Demo
Interface program.
Click on "No" and quit the program.
This could be due to any one of the following
1) HMR3000 is not connected, check the cable for continuity and pin out.
2) HMR3000 is not connected to the specified computer port.
3) Low input voltage (< 5V), adjust the power pack to 6 or 9 V.
4) Incorrect baud rate (19200 factory setting) chosen. Try other baud rates.
5) If this error did not occur during your last session with HMR3000, it may have been configured to send a large
number of messages that the computer can not handle.
Quit the Demo application.
Start a Hyper Terminal session from your Windows platform and be sure to set up this session appropriately
(see HMR3000 User's Guide for details, for eg. with 19200 baud...)
Issue the following command to stop the compass output
#FA0.3=0*27<CR><lf> and try the Demo Program.
If the above did not resolve the problem, call Honeywell.
