Many rigs have a separate jack on the back of the rig for PTT. On Kenwood
rigs, the connection is made through pin 3 on the DIN jack. See your owners
manual for complete connection information.
Some linear amplifiers have 115 volt supplies for their transmit-receive re-
lays. If a transceiver PTT line is used to drive both the DSP-599zx and
a linear amplifier, an isolation relay and/or isolation diode may be re-
quired to prevent damage to the DSP-599zx (and any other solid state
equipment connected to the PTT line).
RTTY Modem Input/Output
To access the internal RTTY modem and all of its features you will need to
configure an output port within setup. You will also need to use one of the
two DIN connectors and the RS-232 port. The DIN connector has all the sig-
nals needed to connect to your transceiver. The RS-232 connector provides
a serial connection to your computer.
DIN Jacks - Radio A and Radio B
The two 8 pin circular DIN connectors (labeled Radio A and Radio B) on
the back panel of the DSP-599zx have redundant line outputs, audio inputs,
and PTT inputs. They also have connections that are reserved for future op-
tions. These connectors provide an alternate single jack connection for each
channel of the DSP-599zx to radio interface.
When using the internal RTTY modem, you will need to use this connector.
The plug is available from Radio Shack (Part #274-026) or other sources.
RS-232 Connector
The DB-9F connector provides a RS-232 compatible connection for the
RTTY modem output to drive a computer. The output is demodulated FSK
in the same code format (Baudot, ASCII, etc.) as the received signal. The
DSP-599zx does not decode or change the signal in any way except for de-
modulation. The computer must have a software application loaded which
can do the decoding and encoding.
