DIP Switch Settings
The TM-U590/U590P is set up at the factory to be appropriate for
almost all users. It does, however, offer some settings for users with
special requirements.
It has DIP switches that allow you to change communication
settings, such as handshaking and parity check, as well as
connection to a customer display.
See Appendix A if you need to make any changes.
