2. RS232 COMMUNICATIONS
The M-227 can shut down the RS232 port on it own if it detects
non-intelligent information on it. This can be caused by ambient
light or improper set up. The RS232 port will not be re-activated
until the power has been re-set. If you are having problems with
RS232 communications, re-set the power and try again.
NOTE
Always keep the plastic dust covers on the RS232 port when not in use.
