PRO / PRO
DATA interface
CONFIGURATION
of the interface...
There are no configuration settings for the interface.
The only configuration you need to make is to your software and in some
cases to your radio.
If your software (and radio configuration) is not set correctly then
you will not get the correct results.
NOTE:
these instructions apply to both the DigiMaster PRO PLUS single and
dual channel interfaces, the single channel interface provides 1 comport
(comport[x]) and has no CAT functionality. When using these instructions
with a single channel interface, references to cat and comport[x+1]
should be ignored.
ALWAYS
ENSURE THAT YOUR INTERFACE IS PLUGGED IN
AND TURNED ON BEFORE STARTING YOUR SOFTWARE.
ALWAYS
TURN YOUR RADIO AND THE INTERFACE OFF WHILE PLUGGING OR UNPLUGGING CABLES.
DOUBLE CHECK CABLE CONNECTIONS ARE CORRECT AND SECURE, THIS MAY SAVE
YOU TIME LATER.
REAR
Connections (Note: The PRO+ has a higher case but
the connections are the same).
ALWAYS ENSURE THAT CONNECTORS ARE FULLY PLUGGED IN, BOTH AT THE INTERFACE
AND AT THE RADIO.

Start
For
connections see the first diagram above.
ALWAYS setup and use the DATA interface section before configuring
the CAT connection.
When configuring the cat section DO NOT assume that your software and
/ or radio settings will be the same as you have used on a previous
CAT interface.
Note: If your radio is a Yaesu and you have a 6 pin DATA socket and
an 8 pin CAT socket be careful and ensure you connect the 6 pin plug
to the 6 pin soscket and the 8 pin plug to the 8 pin socket otherwise
you may damage on or more pins in the 8 pin plug.
Plug the USB cable from the interface into the PC and switch on.
Windows will detect the USB interface and either install the drivers
automatically, or ask you for the driver.
If Windows asks you for the driver, you can download the latest driver
using the link Click
here for latest USB drivers and USB installation guides..
If windows asks you for the driver, you can also decide to allow windows
to "search the net", doing this will ensure that you always
get the latest driver.
After installation of the driver, the LED will alternate green/red several
times, this indicates that the driver has been installed and the the
USB section of the interface is working. With the cables connected to
the radio (specifically the DATA cable) your radio will also switch
between RX and TX several times each time you power up the interface,
this is normal Windows operation and Windows does this to test the interface
each sees the USB device.
You can check driver installation using Device Manager Click
here for help using Windows and Device Manager to identify virtual comports
(PDF).
The LED will toggle RX / TX at every time you power up the interface,
this is Windows normal procedure as it tests the interface and this
action proves the interface is recognise and can be controlled by software.
The LED when green indicates power is on and the interface is in receive.
When red, the LED indicates TX, either DATA or CW.
Open device manager and view comports, you will see 2 comports that
you did not previously have.
If you are unsure which they are, turn the interface off and the 2 comports
will disappear from the comport view.
Switch the interface back on and they will reappear.Windows will also
toggle RX / TX again when it sees the interface power up.
Note the comport numbers, you will need these later when configuring
your software.
REMEMBER, if you swap the interface between USB ports on your PC, Windows
may reassign the virtual comport numbers, if it does so, then your softwares
configuration will need changing to reflect this. The virtual comports
provided by Windows will almost certainly be different on a different
PC.
Windows will assign the 2 comport numbers and there is no way to know
in advance what numbers windows will assign.
However, Windows will normally number these consecutively. I will call
these comports [x] and [x+1].
Comport [x] is used by the interface to control PTT and CW lines.
Configure your DATA mode software so that comport[x] (the lower numbered
of the two new comports) is used for PTT and the "DTR".
Your software needs configuring so that RTS=PTT and DTR=CW. That's all
you
need to do to configure your DATA mode software and you do not configure
comport[x] any further.
REMEMBER, if you swap the interface between USB ports on your PC, Windows
may reassign the virtual comport numbers, if it does so, then your softwares
configuration will need changing to reflect this. The virtual comports
provided by Windows will almost certainly be different on a different
PC.
Configure your radio. The radio will also have a setting for the CW
key, it should be set as a normal / straight key.
Other radios need more configuration, (the
857 for example) when used in DATA modes needs to be set in "DIG"
mode, which you should have previously configured (radios menu system)
to be USR-USB. (consult your radios operator manual).
Many radios that use the 6 pin DATA socket also need to be configured
so that the 6 pin DATA socket is selected for use.
If you don't configure the radio correctly then things probably won't
operate as you would expect.
Advice, DO NOT RELY on using PTT via the CAT system for DATA transmission.
This may work with the majority of radios but some, including ALL Kenwood
radios open only the microphone socket and not the DATA socket when
TXing via the CAT system. Always use the DATA interface (comport[x]
RTS line for PTT and you will always have success when transmitting
DATA.
To
configure the CAT software, you use the second "virtual" comport,
which is comport[x+1], (the higher of the 2 virtual comports created
by the interface - this is NOT the same virtual comport that you just
configured for the DATA interface above).
Some radios like the 817,857,897 have a multifunction CAT socket which
can be set for other use than CAT, if you have one of these radios or
a radio with a multifunction cat socket then you should use the radios
menu system and set the multifunction socket for use as CAT rather than
linear or atu.
Whatever radio you are using you may also need to use the radios menu
system to configure and enable the radio's CAT system before you can
access its CAT capabilities. In all cases where your radio has a menu
system, you should use the menu system to obtain several settings from
the radio. Baudrate, and in the case of Icom the CIV address, (consult
your radios operator manual).
In your software you normally select your radio from a list, then select
the appropriate comport, use the baudrate as set on the radio (this
can often be changed via the radios menu system and so you should check
the setting on the radio), if your using an Icom, then also set the
CIV address (again this can often be set via the radio menu system).
You should double check baudrate and CIV address.
When you have checked the settings on the radio and have duplicated
the settings in the software you then select the comport, this is comport[x+1].
If you specify any parameter wrongly you will not get a CAT connection
but you won't hurt anything.
If you have the parameters set correctly you will get a CAT connection.
In use the PRO relies on you to use Windows volume controls for adjustment
of afsk TX/RX levels, the PRO+ also has external TX/RX adjustments.
DigiMaster
PRO 
On
the DigiMaster PRO+ you also have adjustable RX and TX level controls,
should you wish to increase the range of these controls, the overall
limit is set by Windows volume control (playback and record for TX and
RX).
The
FSK (RTTY) keying is done via comport[x] TXD signal line, (the same
comport as used for PTT - you need to set PTT AND TXD in your FSK software).
HRD does not at this time support FSK.
Configuration
summary for the PRO and the PRO+
The PRO and the PRO+ provide 2 comports, Windows assigns
the comport numbers automatically and you will need to determine what
values Windows has assigned. They will be different on different PCs.
They will always be in the same order [x] and [x+1] (unless you change
them). Your software should be configured as follows;-
Comport[x]
RTS = PTT
DTR = CW
TXD = FSK [RTTY] "Available on the PRO
only". Configure both PTT (RTS) and TXD for FSK RTTY.
Comport[x+1]
CAT control exclusively.
Exact configuration settings are unique for your computer and your radio.
For the benefit of yourself and others, your radios settings and your
software settings can be recorded here;- Users
configurations.
It
is not recommended that you renumber comports unless the comports value
Windows has assigned falls outside the comport range of your software.
eg, Windows assigns comport 24 and 25 but your software only supports
comports 1 to 8... Should you need to renumber comports it is easy to
do so but if you are not familiar with process or not confident, then
you should seek the asistance of someone who is. The "guide to
device manager" - (advanced section) shows how easily it can be
done.
It
is not possible to list the comport configuration for your PC as your
PC will assign and number the comports automatically. Nor is it possible
to list every radio's settings for every piece of CAT software.

(PDF).
Instructions for using your software should be obtained from your software
supplier.
