DHY-04 Serial Connection
Default connection is 19200, e, 8, 1 and using XON/XOFF handshaking.
The serial port has reduced capability compared to the DHY-03 as the setup
and firmware functions have been removed and are implemented by an
embedded webserver.
SCI Software
Sonifex provide free of charge software, SCI, to allow you to manage
connection and control of all aspects of the serial port interface. Go to

The telephone interface parameters are accessible from the webserver for
changing the settings for use on non-standard telephone systems or PABXs
and would not normally need to be changed on standard systems. They are
shown in Appendix A.
Many of these parameters are critical to the correct operation of the DHY-
04. Changing them may impact on the correct working of the unit or cause
the unit to operate in a way that is outside the telecom approval regimes.
Our advice is that the telephone interface parameters should not be
changed without detailed technical knowledge or input from Sonifex. Both
country code and disconnect type tables have reserved entries for future
additions - if you have special requirements for either of these parameters
please contact us with details and we can assess the demand and then add
to the standard list as required.
