4.2.2.9.1 Voter/Ring Down Tone Generation
This grouping allows the DSP-223 to generate a user-defined tone on the Line TX pair in the event of an
active logic signal on Pin 2 of the line connector or Pin-23 (DIG5) of the DB25 connector.
Enable Tone
on Dig5 Input must be checked to enable the feature. Active High sets the polarity of the active logic
signal. If checked, the programmed tone will be generated when an active high is present and no tone will
be generated when low.
The subset feature to polarity is the R1 and R2 check
boxes. When one of these boxes is checked that relay
will close with the active state setting. The relay will also
close from other programmed features.
The
Tone Frequency and Level boxes specify the
frequency and the amplitude of the tone to be summed
with receive audio. Entries of 300-3000Hz are valid.
Typically a –20dBm signal is used. Some
experimentation with this value may be required to get
the proper performance.
Figure 9 Digital 5 Setup Screen
Tone On/OFF Time sets the duty cycle of the tone to create “alarm beeps” generated when DIG5 is
active. Entries of 0 to 65000ms (65000ms = 65 seconds) are the allowed programmable times. An entry
of zero (0) into the field generates a continuous tone.
NOTE: Digital output bits D4 or D5 are not active if DIG4 or DIG5 are enabled
4.2.2.10 Set Gains Button
Figure 10 at the right shows the Gain Set dialog box. A
number of gains can be controlled with this setup
application. This is not a replacement to tuning the unit
correctly with the potentiometers, but a supplement to
allow fine-tuning of the DSP-223 operation.
The
Handset Sidetone Gain allows the volume of the
handset speaker to be adjusted by +/- 10 dB. The Radio
TX Gain allows adjustment of the amplitude of the audio
sent to the radio by +/- 10dB. The Line TX Gain is used
to adjust the Line TX by +/- 10dB. The CTCSS Gain
allows adjustment of the CTCSS tone level by +/- 10dB.
